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 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 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.
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.
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.Read more

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.Read more

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! :-)
Soundware for SynthMaster...
