SynthMaster is an 'all-round' semi-modular software synthesizer and effect plug-in that features many different synthesis methods including VA, Additive, Wavetable, Phase Modulation, Phase Distortion, Frequency Modulation, Pulse Width Modulation, Ring Modulation, Amplitude Modulation, Physical Modeling and SFZ Sample Playback synthesis.

With its multi-synthesis oscillators, analog modelled/digital filters, flexible effects routing with 11 types of high quality effects and a massive modulation architecture with 95 separate modulation sources and 650+ modulation targets, SynthMaster is a powerful instrument for all synthesizer enthusiasts.


  • Cross-platform VST/AU/AAX: SynthMaster runs as a VST/AAX instrument/effect on both Windows and Mac OS X, and as a VST/AU/AAX instrument/effect on Mac OS X.
  • 1700 Factory Presets: SynthMaster comes with 1700 factory presets from a world class team of sound designers: Arksun, BigTone, Michael Kastrup, Rob Lee, Nori Ubukata, Ufuk Kevser, Gercek Dorman, VorpalSound, Vandalism, BluffMonkey, Ümit 'Insigna' Uy, Aiyn Zahev, Frank 'Xenox' Neumann, Teoman Pasinlioglu and Brian 'Xenos' Lee.
  • Semi-Modular Architecture: For each SynthMaster instance, there are 2 layers followed by 2 global effect send buses. Each layer has its own: Arpeggiator, 2 Oscillators, 4 Modulators, 2 Filters, 4 ADSR Envelopes, 2 Multistage Envelopes, 2 2D Envelopes, 2 LFOs and 4 Keyscalers. The modulators can modulate frequency, phase, amplitude or pulse width of the oscillators or any other modulators at audio rate, or they can be used as sub-oscillators.
  • Massive Modulation Architecture: SynthMaster has more than 650 modulation targets and 95 modulation sources including ADSR Envelopes, 2D Envelopes, Multistage Envelopes, LFOs, KeyScalers, Easy Parameters, Vocoder Bands, MIDI Velocity, Aftertouch, Pitch Bend and MIDI CC. Each modulation target can have up to 3 modulation sources. The modulation matrix, which has 64 available slots, has visual filtering as well so that targets for a specific source, or sources for a specific target can be filtered and shown on the user interface.
  • Easy Parameters: SynthMaster features 8 easy knobs and 2 XY pads that can be freely assigned as modulation sources, so that the complexity of the synth engine could be hidden away and only most important parameters of a preset can be controlled by the user. The easy parameters can be globally linked to MIDI controllers, and they can be assigned automatically by SynthMaster as well.
  • Powerful Arpeggiator: The arpeggiator in SynthMaster features classic arpeggiator modes such as Up, Down, UpDown, DownUp, UpDown2, DownUp2, AsPlayed as well as Sequence, Chord, Arpeggiate and DrumKit modes. Each of the 32 steps of the arpeggiator has its own Velocity, Note Number, Note Length, Slide and Hold parameters.
  • Basic Oscillators: 'Basic' oscillators in SynthMaster are capable of synthesizing many different types of waveforms: Sine, Square, Triangle, Sawtooth, Pulse, Noise, any single cycle waveforms and multi-sampled WAV/AIFFs defined in SFZ files.
  • Additive Oscillators: An 'Additive' oscillator is actually 8 'basic' oscillators running together. Each 'basic' oscillator has its own detune, tone, phase/pulse width, frequency and waveform type.
  • Vector Oscillators: A 'Vector' oscillator consists of 4 'basic' oscillators, mixed at different ratios. The mix ratios are determined by 2 orthogonal parameters in 2 dimensions: 'X Index' and 'Y index'.
  • Wavetable Oscillators: A 'Wavetable' oscillator is similar to basic oscillator, except that the waveform can be scanned (interpolated) through up to 16 different waveforms shapes. The position of the waveform can be adjusted using the 'wave index' parameter.
  • Stereo Oscillators with Improved Unison: Oscillators in SynthMaster have stereo output. With the "voices", "voices mix", "pan spread", "detune spread" and "detune curve" parameters, each basic/wavetable oscillator can have its own unison settings which eliminates the need to enable unison for all voice elements.
  • Analog Filters: The 'analog' filters are modelled after the famous ladder filter, so they self oscillate when the filter resonance is maxed out. They have continuously variable slope, which is unique to SynthMaster. There are 3 CPU settings for analog filters: "Basic", "Normal" and "High". With the "Basic" setting, CPU can be reduced by at least 50%.
  • Digital Filters: The 'digital' filters are biquad filters with a hard limiter in their output. The limiter features an envelope follower with attack, release and threshold parameters.
  • Multimode Filters: With the new 'multimode' filter type, it is possible to switch from Lowpass to Bandpass to Highpass filter types continuously. For analog multimode filters, it is also possible to change the slope of the filter continuously from 0 db/oct to 24 db/oct.
  • Dual Filters: With the new 'dual' filter type, two multimode filters can be run simultaneously, either in parallel, or in series. The mix ratios between the filters, and the topology (parallel/series) between them can be changed continuously, as well as the modes and cutoff frequencies of the filters.
  • Comb Filters: Comb filters are digital filters used in physical modeling synthesis.
  • Before/Inside/After Filter Distortion: A distortion stage can be inserted before, after, or even inside the filters. For analog filters, the distortion is applied for each of the 4 filter stages in 'inside' mode.
  • Rich Set of Effects: SynthMaster features 11 different effect types: Distortion, LoFi, Ensemble, Phaser, 6 Band EQ, Compressor, Vocoder, Delay, Chorus, Tremolo, Reverb.
  • Flexible Effects Routing: Each of the 11 effect types can be inserted on any layer insert or on any of the 2 global effect bus inserts.
  • Microtuning: SynthMaster supports Scala tuning, so tuning can be set either for each preset or globally by loading from a Scala tuning file.
  • Preset Browser: SynthMaster features a comprehensive preset browser with separate search criteria for instrument type, preset attributes, music style or preset author.
  • Online Preset Browser: Registered users can upload their presets to the online preset library, or browse and download presets created by other registered users; using the preset browser right inside the plug-in window.
  • Multiple Skins: SynthMaster comes with 3 different skins in different color variations. Using the included user interface editor, users can not only customize the existing skins but also can create their own custom interfaces as well.
  • Import of MIDI patterns as Arpeggiator Sequence: Monophonic or even polyphonic (chord) MIDI patterns can be imported into the arpeggiators in SynthMaster by just drag and drop of the MIDI file onto the arpeggiator view on the plug-in window.
  • Import of WAV/AIFF Multisamples as SFZ definitions: Multisamples in WAV/AIFF formats could be imported into SynthMaster as SFZ definitions, by simply drag and drop of the WAV/AIFF files onto the oscillator waveform view on the plug-in window.

A demo version of SynthMaster is available. It is identical to the standard version except for 3 limitations:

  1. Saving presets is disabled.
  2. The synth starts playing random notes after 15 minutes.
  3. Comes with 800 factory presets (demo users can check out the remaining factory presets from the online presets browser though).

Audio demos of SynthMaster's factory presets can be listened at:

SynthMaster is a very versatile Plugin. Ideal for very complex sound designs. I tried a lot of modular VST/standalone software before, but this piece of a diamont tops them all.

You can do so much things with just one instance of this VST to get outstanding results. Synthmaster is suitable for all kind of electronic sound design, electronic music, even for movie scores or game music or sound effects from another universe.

Two layer sections with awesome oscillators. They are so powerful. With a bright palette of waveforms. Analog waves, digital waves, vintage waves, even waveforms of some big synth legends are available. But the most thing i love about the oscillators is the possibillity to load even own created wavefiles for using as waveforms. So there is no limit for a sound design from another world. Together with the modulation sources like the envelopes, very versatile LFO's, filters, arp sequencer, internal FX routing etc. this is a killer synth. If you take the time and go experimental with this VST, you'll get an awesome sound out of this plugin. I'm also experienced in VST programming and coding, but compared to the programmers of this awesomeness i'm just a small shadow behind you and i have to give very big compliments to the programmers of this masterpiece.

Now let's go a bit into detail:

The Layer section:

There're two layers. Each layer has 2 oscillators, 2 filters, a very good arpeggiator, 3 FX sections with different effects like distortion, lo-fi, ensemble fx, a phaser and an EQ. The oscillators can be modulated by 4 additional oscillators, which are routable as modulation sources. Perfect for FM synthesis, amplitude modulation and destruction of the basic soud of the oscillators. Each layer has its own glide pitchbend range and velocity option, a 8 voice unison with unison detune, unison cutoff and unison panning (stereo spread), each layer hast its own volume and panning control and a coarse pitch.

The oscillators:

The oscillators can load a big bunch of different waveforms. Ideal for any kind of sound creating. And the oscillators have a special option for importing own wavefiles for using them as "wavetables" to make your own waveforms. I love this option. The oscillators can work in multimode with up to 8 voices each osc with a voice mix control, detune, stereo spread, adjustable detune curve, phase spread and tone spreat in the voice section of the oscillators. Each osc has it's own volume and panning control, coarse and fine tuning option, a phase control and a high cut filter control. Very awesome, powerful and versatile oscillators. There should be more VST's with such great oscillators.

The filters:

The two filters of each layer can be split, one filter for each of the main oscillators, then the filters can be switchet to parallel routing or switched in series. Also filters have their own distortion unit to overdrive them. Ten they have a switchable 12/24 dB slope, cutoff, resonance and keytracking control. The filters can be modulated by different sound sources over the mod matrix routing. The filter are sounding very good. they can sound clean, but also harsh and very dirty. I like the sound of the filters very much.

The Arpeggiator:

Each layer has a powerul Arpeggiator with the classic arp modes, a arpeggiate mode, a chord mode for arpeggiated cords, and a sequence mode where you can play own programmed tonal squences with just one pressed note. It has an octave range with up to 4 arpeggiated octaves, a arp stage control with up to 32 stages, a sync control for playing the arp in different synced speed (supports 2/1 to 1/32 bars, 2/1 dotted to 1/32 dotted bars and 2/1 triplet to 1/32 triplet bars) and a velocity control with step, note step + note and step x note. This Arpeggiator is very powerful and the right thing for good arpeggios (as an avid trance musician i love powerful apeggiators like this one).

The Voice Modulation section:

Each layer has 4 routable ADSR envelopes with adjustable envelope curves, two very versatile 2-D envelopes, 2 multi stage envelopes with up to 16 stages, 2 LFO's and a key scaling modulator. The LFO's are loaded with sine, triangle, square, saw, step and glide waveforms, speed, volume, phase and noise control, and an attack and release control with adjustable attack and release curves for fade in/fade out modulation of the LFO's and a final volume control. The envelopes are very fast and crisp, what is very important for my needs as a trance producer. I especially love the possibillity for manually adjustments of the envelope curves.

LFO Section:

There're 4 synth LFO's for each layer. They are the same LFO's with the same functions like the LFO's in the voice modulation settings. They ca be routed via the mod matrix, to control/modulate the individual devices.

The Synth FX section:

The FX section contains:

A vocoder with various modulator inputs: Both layers can be set as modulator with the choice of dry or wet layers, this means with or withot the layer's internal effects. Also an external sound source (audio input) can be routed as modulator input.

2 compressor modules with attack, release, threshold, ratio, knee and ain control and also a sidechain input for the layers and external audio sources.

A nice sounding chorus effect with versatile modulation controls (mix, width, pan, feedback, mod rate and depth, and left and right delay offset).

A tremolo effect, with mix, mod rate, sync left/right ratio and phase settings.

Powerful Delay effect with effect mix control, width, pan, feedback and drive controls, pingpong option and left/right delay times which can be switched to free or synced. Then the delay has a low and high shelf EQ and a distortion effect, which makes it easy to create vintage style delay effects like e.g. tape echos or tube delays.

And finally a very good sounding Reverb. It has a mix, size, time and distance control, early and late reflections section with own EQ's and an early/late mix control. A mod amount and a mod speed control, and finally a diffusion, a density and a damping control. But the reverb can be very CPU hungry with long reverb tails.

The FX section has 5 insert slots for each layer where you can rote the several effects to one of the slots. It also contains a global fx routing section with 2 layer send busses with dry/wet controls for each layer and 5 insert slots per bus, where you can rote the several effects to one of the slots.

The Modulation matrix:

The mod matrix has 64 routing slots, each with source and destination routings of most of the modulator devices and a bipolar amount control for each single slot. With this matrix you can create all your modulation routings like volume/filter/pitch/panning modulations and much more.

The output control:

It contains volume and bypass controls for each single layer, a master volume control with an additional +12 dB boost button and a master tune control.

And finally the main settings option:

It cotains the options for changing the GUI skin, the plugin window scale, the global pitchbend range settings (which can also be set individually for each layer and each single preset), the global engine quality and engine buffer size settings (can also be set individually for each single preset). It also contains settings for default loaded standard saw/triangle/square waves for the oscillators while resetting the preset to default. Then there are controls for antialiased drawing, MIDI CC filter lag, mouse filter lag, bipolar easy knob control, and a hide older presets option.

I also like the preset manager. It's very comfortable and makes it easy to browse between the banks and the presets and the Bank/preset categories.

This VST is awesome, it has so much power. If you take the time and learn, how to use this plugin, this VST can be a huge sound monster. And for its complexity and sound quality it is very CPU friendly. At the beginning it needs a bit acclimatization, but when you then broke the ice, it's very user friendly.

Again, big respect to the programmers, big big compliment for creating such a sound weapon.

This is not just a VST, this is great, great art.

My Points: 10/10.

My review for Synthmaster is based off of the new update v2.7.5 which has seen a lot of key improvements in an already flourishing product. I conduct reviews differently, as I try to initially give my expectations, the good points and then the points that I feel need to be improved. It also needs to be said I'm am not the deepest guy into making my own sounds, so I may be speaking from a different perspective than most.

My brother purchased Synthmaster a couple of versions ago. I was against it because it looked kind of complicated and around that time Synthmaster was EVERYWHERE. I'm kind of backwards and I like to go for tools (& music) that most don't listen to. However, he was dead set against my opinion and purchased it anyways. About 6 months later he upgraded to the everything bundle which was on sale at the time. I thought he was crazy, but since he is my brother, I couldn't resist trying out for free. (I see you pointing your finger! My brother chose to let me install one of his 5 licenses on my computer. Now back away KVR police!) Needless to say, my expectations initially weren't that high for Synthmaster, mostly because it didn't look like it would be my cup of tea.

I gave it an honest try and I was really blown away by SM's sound!! In fact, of all the synths I tried, SM has the most solid sound. What I mean by solid is SM is unapologetically a digital synth and puts out EXACTLY what you put in. It's like a Kotelnikov of synths and THAT I like. Whatever sound I used, I could definitely see myself using for productions. With the newest update, the CPU for using the analog filters was reduced. My computer is a little newer, so CPU usage wasn't really a concern initially, but now it's really better.

The things I like about SM are that with so many sounds, this COULD be the only synth that you could need/use to make music. Being it's mostly a wavetable synth, you can make it sound like whatever you want to, but have have immense control over the outcome. I usually never get past using 1 layer, but it's nice to know that I have another available. The addition of the oscillator algorithms & unison control gives more refinement to an already powerful synth. Not to mention being able to use the modulators as a sub-oscillators! The effects are simply outstanding and do not feel like they were just added on. The arp is implemented well. I love that you modulate each oscillators with 4 more oscillators AND... the kicker.... the ability to import SFZ files! Though many opcodes aren't supported, I can use sounds from some of the Zampler free downloads and load them up in this baby and have more control. The 4 ASDRS, 2d envelopes, 2 MSEGS & 6 LFOS gives you so much control that it's mind boggling sometimes. The filters are really digital sounding, but are VERY precise. Not to mention, with all of those presets, the browser comes in handy and is implemented fairly well for the most part. There is a mod matrix with 64 slots, 2 buses of effects, 2 XY pads, 8 easy knobs & even an FX version. Again, this is a VST I would use for all of my synth sounds.. ALMOST desert island territory here.

Now, what I don't like is with all of this power going on, most of the time, SM to me feel like it's always a work in progress. There are some quirks that are annoying that have been going on for a long time that are really annoying. For one, after awhile of using SM, some of the waveforms may start to disappear. There is a workaround for this which includes deleting a temp file, but it's something that catches you off guard and shouldn't be happening.

The display really still baffles me sometimes. It's the looks of the GUI but just how it's organized. In all other synths I have ever seen, you will see a familiar flow of oscillator functions first, controllers, filters then maybe routings later. Because the GUI designer was going for something different here, its not bad, but I get really confused when I start working because my eyes are tricked into going down to the Oscillator section first, the crossed over to the filter then down to the controls then at the top left for routing. I just feel this should all be switched around. I could probably just rearrange this myself and make a new skin, but SM has A LOT of elements in which making a new skin seems like too daunting of a task for someone like me. Sometimes, I feel the filters could have a little more UMPH to them as well.

In dealing with SFZ, it's understandable that not all opcodes will be used, but I wish the opcodes that are used was made more apparent in the manual. SM could be used as a basic rompler in this fashion if more people new exactly what was needed. Though there are tons of single waveforms inside, SFZ is a great way to import sounds in the same interface and have all of your sounds coincide (I guess you could also use the FX version for that as well with another sampler if need be).

When making favorites, I wish that there was a convenient way to browse them. As of now, the favorites folder is just a long list (if you have a lot of favorite of course) and it's similar to the rest of the preset browser screens in SM. With so many presets available, I think something like this is necessary. Also, the Bit Depth & Drift knobs have recently been removed from the ASDRs, though not heavily used by others, I personally would like them to stay as I use them to add some personality to my sounds. These are all really annoyances rather than extremities that takeaway from Synthmaster as a whole, but they should be addressed.

Bulent, the developer has stated a timeline of updates that will be coming, including granular synthesis & an internal SFZ editor. These are located on the following thread: http://www.kvraudio.com/forum/viewtopic.php?p=6203340#p6203340.

Let's hope that plans don't change at KV331.

Besides that, I really think that you can't really squeeze any more into an already bulging product. The SM Player is also available for those who just want to use the presets (this was released after my brother purchased however) and also an iPad version. It seems that SM is still gaining ground.

Personally, I can't find too much fault with this this synth besides it's layout mostly. For this reason alone it is my #3 synth to use and not numero uno. I'm not the GUI police, but I think with all of the changes a more understandable flow could be perceived. That along with a favorite's browser & stopping those disappearing waveforms, I would be all about using this for every production. The sound is immaculate and on that point alone I recommend that everyone try this synth if you know what you are doing with synthesis or try the player version if you are still learning.

H'yall, just wanted to say a few nice things about SynthMaster 2.6.

I've been struggling to find time to get things done and SynthMaster is one of those tools that I just got up and running within an hour.

The flow of the interface is something I can relate to, and the ARP section is what I really wanted, after managing the complexity of external ARPs.

Just preferred to use this synth like my old keys like JP8000 or XP80. Select some sources, route them through basic ENV and filters. leave some stuff clean, some distorted and start jamming away on my DAW or micro host for inspiration.

Presets are good, and if you think they're not suited for your setup then tweak and save or build from scratch. I'm getting the vibe of a musician coming back to me as I play this synth. Instead of being an engineer or designer for which I use other soft synths or plugins. Switching between patches is fast enough for producing stuff but I'm not too sure how it'll do 'live' if you have the courage to use it stand alone, on the stage.

Remember to use a good quality headphones when you work with it, especially if you think it doesn't sound good. I have studio monitors, FOH reinforcement speakers and headphones for use when creating new patches/presets, or for just about anything that need to go up, out there.

There's highs, lows and a full range of sounds flowing from this synth, and if I want to add on, there are exciters and psycho acoustic bass enhancers in my software cabinet. I've tried a few more costly soft synths and I prefer this one because of the balanced sound. Either in the filter algorithms or some harmonic processing, whatever it is I was taken in by the vibe of using this one synth for creating, jamming out notes, phrases, chords and ARPs......... YEAH!

Good work KV331 Audio! :-)

I wanna make a short review only, because much things are said and some of them are making me really angry.

So here is my opinion:
1. The gui is very intuitive but very complex, too. You get fast results if you know what you do.
If you don't know what you do, look in the manual or buy a synths that isnt as complex as synthmaster!
If you wanna have a gui like Diva, buy Diva! I think, these people go into an Adidas-Shop and say they want a shirt that looks like nike, too. Or they buy a Pc and complain that the PC is much more complicated than the pocket calculator they used so many years without any problems and without reading a manual.

2. The sound and the presets: Sound is fantastic - from hard to soft you can all do it! Especially the presets are genius! Never heard a synth that had so many presets which are used in commercial Dancemusic like Synthmaster! And a preset is a preset, is a preset..... A preset is a startingpoint for your music, nothing more. To the guys that say the presets are uninspiring: Sorry, you are only untalented and uncreative! I hate this presets where you hit a button and "get blown away" or even get a melody, because you can only use them once, or better: you never should use them because 1000ds of untalented guys used the preset already.
And then everybody is wondering why the electronic-scene goes down, noone is earning money any more, because the market is flooded with so many untalented "artists" that are searching for the
"Make a whole song" button in a synth.
I love the presets and sometimes I get an aha experience when I use a preset i didn't like before und play it in a different way, in a different song. "Ahh! Now I know what the
Designer thought as he made the preset....."
Another thing is, that the presets fit perfectly into an modern electronic arrangement. Thats a sign for professionalism!
And!!! Insigna is the best Sounddesigner of all!!!!
And!!! KVR should claim over 200 Dollar only for the Factory-Version! And 200 Dollar is not enough.
And!!! The idea of an online-preset-bank is fantastic! But why are only so few people uploading??? Perhaps they are busy with complaining about uninspiring presets........

If every user uploads 5 of his best presets we had the best and biggest Preset-bank ever!!.

So thats all for today!
Sorry for my bad english.
Thanks to KVR, thanks to Insigna.

Well, as with anything related to music -- it is all very subjective... I got it a week ago, and having wonderful time with it. Already put it in production use, and it is VERY inspiring for ME. One thing I would agree -- the main rule of GUI design had been broken (do not surprise the user). Very powerful and fat sounding. Arpeggiator section just blew me away. My 2C.

27 September 2012 at 6:17pmkv331

Hey Sasha,

Main rule of GUI design, what's that?

We really want to improve the GUI. What would you suggest?



28 September 2012 at 6:58amjam92189

well maybe for some people setting things up with more of a tab setup would be better. honestly I cant think of any real things to improve on for something that kind of does it all. to much to really slim down.

28 September 2012 at 6:59amjam92189

I like some of these sounds I am going to pick up a few when I get paid.

28 September 2012 at 9:42pmsasha_perl@yahoo.com

Sorry, If I wasn't too clear, let me expand on that.

But first, let me thank you one more time for the product. Special kudos for CPU/ASIO utilization. Very light, great programming indeed.

After spending more time with the synth, I really can suggest only couple of things, both of them are related to the preset browser:

1. Search. it is asking for it, really. Alphabetic sorting is good, but... You know :)

2. Grouping is a bit confusing, especially with not quite so obvious with italic fonts and all.

Do I make sense?

Once again -- thank you. Having so much creative fun!

2 May 2014 at 1:24amcaitiffchoir

Agreed. This post is over a year and a half old, and still there doesn't seem to be a search bar when looking for a preset... (i just bought it two weeks ago)

and the manual for this AWESOME synth is sorely insufficient. This is a very, very powerful synth with a lot of capacity, but given that, a more in depth explanation of some of the controls, routing, tabs, drop menus, etc (I can't even find anything in the manual telling me how to load presets I have saved o my computer) seems appropriate...

8 December 2012 at 5:12pmliquidsound

Can you elaborate on the issue of not being able to "identify" what's possible?

I'm actually overwhelmed by this synth capabilities and I'm working with Zebra, Blue and Diversion ATM.

I bought it long ago for less but today I would spend way more to have it.

The optional expansions really shows off what it can be done (and and I'm with you for the standard presets not being enough to demonstrate the depths of this incredible synth) but there too, the expansion are far from covering the enormous spectrum of sounds that Synthmaster can achieve with the different synthesis types available.

The interface it's trying to deal with the multiple, quite a luxury indeed, tools at your disposal and to be fair they did a good job indeed but I don't think there is much more that can be done without changing completely the approach.

Zebra is unique in that sense.

Yes, a scalable GUI would be welcome and popsUp windows such the wave shaper of the old z3ta for detail work on some envelops.

11 December 2012 at 2:33pmxcentric

Would be nice if it had Polyphonic glide/portamento.

4 January 2013 at 3:11pmdakkra

How would Synthmaster track poly glide? If you have a chord consisting of two notes and you switch both of them how would SM know wich note to glide to its' second note?

12 February 2013 at 6:35pmkv331

Poly glide is currently not supported.

10 January 2013 at 7:03amGernburgs
I think you should make the GUI more analog-looking, as opposed to 100% digital. I like the look of something like DUNE or DIVA where there's a more real-life look to them. Synthmaster is more like Straightliner as far as looks go. I just think the more genuine feel is visually appealing. The synth sounds great though. No need to change much there. The ocillators sound incredible.
20 March 2013 at 6:46pmbharris22

Which Nori preset pack are you talking about specifically - the Art Rock pack? Thanks.


19 May 2013 at 11:25pmyessongs

great organs and trons in that preset pack but if you are into YES, Genesis, Pink Floyd, ELP and other prog rock greats then Nori has other preset banks you will want and these alone make it worth getting synthmaster and in fact it being a true desert island synth if you could only have one this is it.

25 May 2013 at 8:23pmBitArts

I wrote a review on Synthmaster and am told now, I need to have ten posts on the forum before reviewing the product? Is this a joke? I'd actually guess, I don't need to post for no reason, just to be able to write a review. Having bought and used the product is a basis to review. Not posting random stuff in advance.

So I'm gonna post mine here then:


A lot of people have described all the positive things and I don't want to just repeat these. There are indeed a lot, that make this VST stand out from others. Yet I haven't read much about the disadvantages, limitations and problems, that come with Synthmaster.

So instead of singing a hymn on the sound and things it's capable of, I'm gonna focus in this review on the opposite and will try to point out some issues and expectations, that aren't fulfilled .


1. The very first thing that got my attention, was the rough, inaccurate parameter handling in Synthmaster. Values displayed in the panel don't change, while the knob indicator does. That means for example, when you're changing a filter cutoff frequency, the knob indicator counts from 34.0 to 34.1, 34.2, 34.3 etc while the related frequency value remains all the time the same with 87,7 Hz. At 35.0 then it immediately switches to 92.9 Hz. What happens in between? I've tried to setup my own formant filters this way, which turned out to be an impossible taks with a parameter handling like that. On higher frequencies the gaps between the displayed values have a size of up to 1kHz! Why aren't the values in between displayed? How is anyone supposed to do accurate settings this way, like e.g. absolutely essential and necessary for formant filters? It's simply impossible.

The even worse thing is, this inaccurate knob behavior goes for absolutely ALL knobs spread over the GUI. Working with something like this in a production is a plain horror to me.

2. No matter what natural instrument you play, if you plug a string, play a key or hit a drum. It usually is a single sound that comes from the instrument on a hit, strike or what ever you want to call it. No instrument does any layering of the ADSR from the former played notes, when you hit the exactly same key again and again and again. The sound would always start over from the beginning. Maybe with a variant sound, but: it starts over! And that's exactly NOT, what Synthmaster does everytime a ADSR phase hasn't arrived at its end. Synthmaster just keeps playing the sound and simply layers a new voice over the exactly same note. The support confirmed this unlogical and unnatural instrument behavior. In practice this produces amplitude layerings without any need and can easily produce volume peaks and other sound problems without any intention or anything wrong in the actual sound design or usage. And of course the result is also redundant CPU usage without any need.


1. There are three filter structures offered in the Layer section: split, parallel and series. The fourth possible configuration (split series = OSC1 -> Filter1->Filter2, OSC2 ->Filter2) for some reason is completely missing. If you're heading for this config, this forces you to waste the second Layer and also setup all the things like filters, envelopes, etc. a second time. Though you'd actually require all these only once. But more on THAT later.


1. The Detune knob has its own life. As soon, as you switch to multiple voices for a unison sound, the dedicated Detune-parameter loses its bipolarity and you instantly get a pitchwise 50% spread sound. Okay. If you now go the other way around and change back from a non-spread and well pitched unison config to a single voice, the result usually is a horrible detuned single voice. That'd make a kinda sense, if there wasn't any Fine Tuning knob and the Detune knob had a double function. But there IS a Fine Tuning knob and the behavior of the Detune appears like pure nonsense. Simply deactivating the Detune parameter, when only 1 voice is selected, would easily solve this. In the Layer section the Detune works exactly like that. In the Oscillator section instead you get these off-pitch results, that make your eyes look cross over your nose, as soon as you hit a key.

2. The Modulators
This to me is one of the real disappointments. There is no real modulation matrix. The modulation routings are predefined by some fixed configs, instead of offering a completely flexible and open matrix like in FM8, Toxic Biohazard or Sytrus for example. And more sad, you can't modulate your carrier with any resonance filtered modulators. Instead, with the "Tone" knob only some kind of very simple (and non-resonant) lowpass filter on the waveform is available. Cross-Oscillator or Cross-Layer modulation isn't possible at all. Most of the currently hip FM growl and scream sounds are actually almost impossible to do with the usual standard waveforms and these limitations.

Beside that there are bugs like for example this one:
When selecting "mod 3+4" as modulator for an oscillator, the display says "mod 2+4" then. Is this a typo or a real misconfig now? I have no idea. I didn't feel like figuring out, how it's now handling this.

3. Synthesis Types
- For the "Basic" synthesis, if you need to inverse your waveform, you have to render it handish yourself and add it to the user library. Way too complicated and time consuming, when a simple "Inverse"-button could easily solve this for all waveforms. Additive Synthesis has this button.

- "Additive" synthesis comes with 8 bands only. An old Hammond B3 organ has 9. The well known Kawai K5000 from 1997 had 128. Of course you could simulate more bands using prepared waveform cycles, but that's not really additive synthesis anymore. The additive synthesis engine in Synthmaster is a VERY basic aproach only. To me this part appears more like an 8-part waveform layering engine. Useful in a way, but far away from being an additive synthesizer with a practical use as such for complex, really additive sounds generated with sinewaves.

1. What I'm missing really bad here, is a vowel/formant filter, capable of at least the standard vowels. Like described above, the rough parameter handling additionally makes it impossible to setup your own.

Envelopes & LFOs:

This to me was the main reason to buy Synthmaster. It appeared like a huge, damn LFO modulation monster. And in some way it is indeed. But have you ever tried to sync your LFOs?

1. Multi-Stage LFOs (Mstg1+2)
These are actually very powerful tools and helpers. Actually. It turned out, in Synthmaster they are completely useless. At least if your trying to create something else than insane and random chaos in your sound. NI Massive uses this kind of LFOs to achieve accurate sequencing of varying filter sweeps and wobbles for example. Those typical moving and driving dubstep sounds you can enjoy by pressing a single key. If you try to do something like this in Synthmaster, you'll find yourself very soon near a mental crack-up. Absolutely nothing on these LFOs makes any sense or works like expected. Manual timing doesn't work because of the above mentioned rough parameter handling, so you're unable to set accurate timing by hand. Using the Sync option also has absolutely no effect. What you get then, is a kinda grid, that doesn't make any sense at all, nor obviously is related to accurate host timing. Activating the Sync option also doesn't tell you, what you are synced to now. 1/1? Per single field of the grid? 1/16, 1/8? Per loop points? How do I set the speed of these LFOs? None knows and meanwhile having tried everything I can imagine, I'd actually think, these LFOs are synced to the moon phase of some random planet far far away, or maybe your neighbours VST host tempo, inverted and divided by Pi. Adding "Stages" in these LFOs adds spline curves, with absolutely no relation to the synced timing. Start & End of the loop are related to what? The stages? Sync Points? Again something none knows, because their settings lead to results, that don't make any sense at all. Using two Stages and setting the Loop start to 1 and End to 2, with infinite loops should actually repeat these two stages then, right? Well, it doesn't. Setting the end to 3 does, so this might be related to the Stages end points. Maybe. But then, even with Sync enabled and considering the Stages end points, your totally unable to get a synced sound.

I've reported the whole thing as a bug and got the response, I'd get a proper working example preset sent. Well, I didn't receive any till today and am not really surprised about it. The whole Multi-Stage LFO-feature is a total fail on absolutely all levels and does absolutely NOTHING of what you'd expect it to do.

2. LFOs
A quite standard thing you'd think, right? Well, they are and they work properly, when you're using them for unrelated stuff. But then again there's that thing about host syncing. Since the Multi-Stage LFOs don't work, you'd have to use the standard LFOs for some less complex wobbles, right? And of course these would have to be synced again. As you might already expect, this too isn't as simple, as it might seem. First let me say, at least some of the expected syncing works, if you regard a few things. For the standard LFOs you can choose a sync resolution, set the LFO speed knob to 127 and... that's it. End of sync story. Your LFO will work accurate only with exactly that speed you chose and you're not able to change that speed while keeping the whole thing in sync. Setting your sync to 1/16 and changing the LFO speed via button to 50% would lead to 1/8 you think? Well, it doesn't. The result is something near 1/8. Just the rough paramter handling you already know from the rest. This is just one example with some obvious values. It also doesn't work with other values. Okay, what now? We could modulate the resolution setting instead, right? Wrong! You can't change it, neither from within the synth, nor from the host via instrument automation. Accurate wobbles with changing speeds in Synthmaster? Dream on and enjoy your dream. Because reality has an ugly face.

Each and every synced wobble sound with varying speeds you get on synthmaster will be out of sync. And it's not the sound designers fault. It's a pure Synthmaster problem. I've also reported this as a bug and got the response, the sound designers hadn't complained about this yet. Well, I'd guess it's about time then.

3. Synth LFOs & envelopes
Why I make this a point is, I can't understand why it's possible to spend global LFOs to the synth, but no global envelopes. I find it quite annoying, to be forced to setup the exactly same ADSR envelope twice, when I actually only need one. Why aren't there global Synth Envelopes, when LFOs of the same state are possible? Another thing, that doesn't make any sense to me. And even if it's necessary to stay with separate envelopes, a copy or transfer functionality from layer to layer would be a nice help. Which actually goes for all component paramters of layers and oscillators, that could be shared. But it's not there.


Okay, enough for now. This became already longer than intended. :) But I guess, this gives a good view on the "less shiny side". In fact it's not all 10/10, if you're caring about designing sounds yourself. Withotu a doubt, the things Synthmaster does like expected are done really well. And it sounds outstanding in many ways and for several reasons. But there really isn't only light all over the place.



29 May 2013 at 2:28pmBitArts

Just some clarification, refering to my posting above. :).

This was/is just very detailed description of some momentary issues remained. Remained in a very complex project. Happens. Period. Because of these things, that are constantly debugged anyway, Synthmaster still and for sure has no reason to hide. In fact it is, easily despite the things I mentioned, my absolutely favorite synth atm. And believe me, I'm really using it on hardcore level. Most "normal" users probably won't even ever come along half of the issues. And let's face it: Describing all the positive things on the same detail level, would easily have taken tens of multiples of the space the issues required.

So please, don't fool yourself by reading my recent posting in a way it's not meant. I agree on almost all positive things the users before me listed and just didn't want to repeat them all. Still it's all there. And I appreciate it all. so, if you've got the chance to get your hands on Synthmaster, I strongly recommend to get it! You hardly will find something better for your money atm.

The passion kv331/Bulent works with and the frequency he provides enhancements and updates with, makes me feel confident to give Synthmaster 11/10 with my next review in a while. ;))) Okay, that was kinda bootlicking. :-D.

But seriously, I felt the need to avoid misunderstandings and clarify that. Cheers.

I just purchased this two days ago and I still haven't picked my jaw off of the floor. After spending 12 hours on it straight today, still haven't encountered any obstacles preventing me from making the sounds I want... and just when I come up with another whacky idea for a sound, I find KV331 has already provided the means to achieve the routing. I truly think it's safe to say that everything seems to have been thought of in advance!
Okay, I'll admit that I too was a bit daunted by the GUI at first, but after I figured my way around it, there's no going back. If I could post a review, I'd give this a 10/10. Since I can't, this will have to do:
This VST is worth every damn penny and more.

11 August 2013 at 1:03pmDigiArc

I just purchased this for myself and my daughter. I've been producing for years but she is 14 and I wanted something we could learn together and for her to have one versatile synth to get deep into. I'm in to program rock and she is in to Dub and EDM. Synthmaster has us both covered with tremendous versatility. I want to say thanks for a very reasonably priced, very powerful softsynth. I'm looking forward to further development. Particularly in the wavetable area.

I have one big feature request that I'll post over in the forum: Please move the settings and presets to the user appdata area in Windows like the majority of other synth makers.

Thanks again.

12 August 2013 at 3:37amtonytungsten

I am having some exxxxxxtremely annoying issues with this synth, which really pains me because i am trying to master this synth and make it my go-to. One glaring issue i am having right now is that i am copying the patch FX Tri-Pipe by Insigna to study. I have copied every parameter, and i mean eeevvvry parameter exactly the same as the original but my patch sounds a lot duller in comparison. One thing i am noticing is when i copy the parameters for the easy controls, the settings to not match up at all. In the original they are set to (+) modulation as are mine but for example my delay wont start affecting the sound till the knob is at 50% and passed that the delay cascades like crazy, whereas in the original the delay begins affecting the sound withing the first 50%. Does this have anything to do with the way the Dry/Wet settings are set prior to assigning the easy controls? Could somebody else please try to copy this patch and get back to me cuz i am literally dieing right now haha. I can't figure this out and i feel like i've wasted so much time programming on a faulty synth. another thing that happened when i was building this sound is that the original sound completely disapeared and all that was left was reverb, regardless of the dry/wet setting. did not work again till i reopened synthmaster. And when i try to map an ADSR envelope to the frequency of the multiband eq in order to sweep the band, synthmaster crashes, as soon as i select the envelope as a modulator. Your help is greatly appreciated, i want this to be my favorite synth again... I am pretty sure i am using the latest update 2.6.3, is there a way i can tell from the GUI? and i am using the current generation 15 macbook bro, fully loaded.

P.S. I am absolutely positive i have copied all parameters the exact same. such a pain....

Your assistance is GGGGRRRREEEEAAAAAATTTLLLLYYYYY appreciated.


14 August 2013 at 12:32pmkv331

I think I know what the problem is: His easy parameter settings are unipolar. i.e. between 0 and 1. Later on we made the easy parameters bipolar between -1 +1. So when copying his easy parameter settings, please add offset to the easy parameters.

For instance if the easy parameter value was at zero, you set it to 64 (12 o clock).

I hope this helps, I'll try to fix this in general.

3 October 2013 at 7:58pmdjdocrok

I really like the way this synth sounds. UNFORTUNATELY, I cannot run it for more than 5-10 minutes at a time without it fatally crashing Ableton. Every. Single. Time. So, it is now completely useless. Plus, tech support is a complete joke - emailed them numerous times about the problem, got 1/2 of one response, and now nothing for months. What kind of show are you guys running here? I use a number of other VSTs with no problems - Massive, Nexus, Komplete, Sylenth, you name it - ONLY this plug in is guaranteed to crash my system within minutes of use. I can't speak for how well it works with other DAW's, but their lack of customer service would make me wary regardless. It's really too bad because it DOES sound good, but that's not much use if you CAN'T USE IT.

12 November 2013 at 10:02amkv331

I asked for step by step test case to reproduce the issue. Unless I have a reproduceable case I can not fix the issue.

12 August 2015 at 12:48amdjdocrok

As an update, the 64-bit runs flawlessly in Ableton, so there's that. Recently re-discovered it after switching to an all 64-bit system and it's been working great. Not sure if the customer service has improved but they certainly seem quick on the reply on here at least.

14 January 2014 at 9:45pmvintagefly

I like Synthmaster a lot. It has a great sound which is really warm and smooth, great possibilities and for me as a wavetable fan, I can load any waveform I want and switch through them easily in the basic oscillators. It would be great though to have that back and forth button for waveform selection in all other oscillators that can use waveforms too! And I would find it REALLY inspiring if Synthmaster would have a "select random waveform from all waveforms available"-button wherever waveforms can be used. Now that would be great.

Most people complain about the GUI here, I find it absolutely straight forward for what Synthmaster can do it pretty much allows me to access everything quickly. I like it a lot! I also didn't need much time to get into it. You just have to get your head free of the "it must look like all other synthesizers or it must look like an analog synth".

21 March 2014 at 7:41pmdawisk

Anyone know a simple way to make favorites a selectable bank? I have a lot of them...Thanks.

22 March 2014 at 1:18amBlackWinny

A preset yes.

A bank no.Maybe for a next release...

21 April 2014 at 5:22amMadAnthony81

Id like to say first of all, synthmaster sounds excellent. Its great for electro. I find that synthmaster is tedious to program because theres of little buttons to push. It would be nice if buttons wre consolidated and larger. It freezes on me and takes lots of CPU.

All in all, im a proud owner of Synthmaster for my dubstep and electro. Its possible with work to get real real gritty, but it is still a smooth synth right to the end.

21 April 2014 at 6:10amkv331

Have you downloaded latest update 2.6.15 ? We changed the unison implementation a little bit to limit polyphony further. We have lots of presets with unison AND analog filters and they DO consume a LOT of CPU.Reducing polyphony, or using Osc Voices instead of Unison DO help a lot.

22 April 2014 at 5:28pmokrra

ok so i chnaged the skin to the grey player and cant change it back?

was really enjoying my seesion until then.

22 April 2014 at 5:39pmmikemusicked


Several of us did the same thing. Bulent posted the solution on their Facebook Page https://www.facebook.com/synthmastersoftsynth

It's easy to go back to the SynthMaster skins: On the top header (of Player), click on the left/right arrows to change the current displayed parameter, until Global Skin is shown. Then, click on the skin name to select the new skin from the dropdown menu. Close/reopen the plugin window and you're back!

Make sure you go to GLOBAL skin not the first skin page you get to.


10 July 2015 at 6:48pmmatteogk

It's always a matter of "how it sounds" and how comfortable I feel when I use a plugin: and Synthmaster sounds great to me. Whatever else counts nothing. It's a matter of taste, of course.

My 2 cents.

12 July 2015 at 10:00amMaddcow

I tried SynthMaster yesterday and as a wind controller player, I fell in love with the modulation options. I'm not keen on all the Echo on a majority of the factory patches but that's dead simple to adjust. I'm probably going to buy the Everything Upgrade now.

11 August 2015 at 11:57pmHoosierGuy

Awesome Synth with almost unlimited capabilities...also a great value for the money. A little slow on responding to email requests for tech support though.

12 August 2015 at 12:37amkv331

Hey, when did you contact us? did you do that through our website ?

10 November 2015 at 8:52pmgaf_thit

Great review, mastrcode. Inspiring to read and just cured my GAS. Will try to go in-depth with synthmaster ;-)

And thank you for your great plugins too.

27 November 2015 at 7:10pmhempelr

I've bought synthmaster player and one expansion pack on 21st of november, last saturday and wouldn't download because my music-pc wasn't ready yet. Now I would use the mailed download link today, but it runs into nothing, a failure site comes. What the hell is that? Is my money lost? I'm very angry about that - and nobody did answer till now on my emailqestion.

I feel cheatet - 15 Dollars are burned...

How can I get my payed software? Who can give me a new, but functional, link to download, what I have payed?

Hope, that someone can solve that big problem.

27 November 2015 at 9:11pmkv331

Did you contact us at http://www.synthmaster.com/contactus.aspx.

We can not help you over here without knowing your name and email address.

28 November 2015 at 12:06pmhempelr

Thank you - the support was 1st class.

That have to honored - because this is not selv-evident, that on complaints will be so fast and satisfactory answerd.

Now I can try synthmaster and fiddle around it ;-)

Nice Advent to all.


23 May 2016 at 5:25amtommyzai

Top-notch support! Very responsive.

20 March 2017 at 9:32pmmoono

Could I use Synthmaster for new patches inside Fishman TriplePlay ?



28 December 2017 at 8:16pmkv331

so the other 999 never crashes your DAW? OMG! I sent you a PM so that we could resolve your issue quickly.
