SynthMaster One

SynthMaster One is an easy to use wavetable synthesizer with an intuitive workflow. Although it shares the same engine with its bigger brother SynthMaster, it comes with new features like wavetable synthesis. With its simple layout, rich wavetable/waveform content and inspiring factory presets library, designing new sounds with SynthMaster One is very easy.


  • Cross-platform VST and AU: SynthMaster One runs as a VST instrument on both Windows and Mac OS X, and also as an Audio Unit instrument on Mac OS X. On Windows, it runs as a standalone application as well.

  • 1200 NKS Compatible Factory Presets: SynthMaster One comes with 1200 inspiring factory presets from a world class team of sound designers: Arksun, Aiyn Zahev, Brian Transeau, Bulent Biyikoglu, Electronisounds, Gercek Dorman, Kurt Ader, Luke Neptune, Mirko Ruta, Nori Ubukata, Rob Lee, Ufuk Kevser, The Machine, Venus Theory, Vorpal Sound and Xenos Soundworks. All of those factory presets are NKS compatible, so they can easily be previewed/tweaked inside Komplete Kontrol/Maschine hardware/software.

  • Semi-Modular Architecture: For each SynthMaster One instance, there are 2 oscillators with 2 sub oscillators, 2 Filters, 4 ADSR Envelopes, 2 LFOs, a powerful 16 step arpeggiator/sequencer and also 11 different efffects that can be inserted on to 6 FX insert slots. The sub oscillators can be connected to the oscillators in 5 different modes which let you use it as a regular sub oscillator or do complex modulations such as ring modulation, amplitude modulation, phase modulation or frequency modulation.

  • Wavetable Synthesis: SynthMaster One implements true wavetable synthesis which opens up new possibilities for sound design. Unlike SynthMaster where you can sequence up to 16 waveforms to create a wavetable, you can import wave files that contain wavetables into SynthMaster One and use them in your projects. SynthMaster One comes with a rich wavetable library and you can extend that by placing wavetables under the Waveforms folder of SynthMaster One.

  • Stereo Oscillators with up to 16 voices Unison: Each of the 2 oscillators in SynthMaster One have stereo output, and can have up to 16 voices "unison". Using the "voices", "voices mix", "detune curve", "detune spread", "pan stread", "tone spread" and "phase spread" parameters, each oscillator can generate a rich "supersaw" type sound.

  • Sub Oscillators: Each of the 2 oscillators in SynthMaster One has a sub oscillator, which can operate in different ways: Sub (+), Ring Modulation, Amplitude Modulation, Phase Modulation or Frequency Modulation. The Sub Oscillator can also synthesize different types of noise.

  • Zero Delay Feedback Filters: Each filter in SynthMaster One has 4 different categories: Ladded, Diode Ladder, State Variable and Bite. All of those filter algorithms are developed using the zero delay feedback filter technology. With advanced filter parameters like input gain, drive and acid, you can get that "analog" sound from the filters.

  • Rich Set of Effects: SynthMaster One features 11 different effect types: Distortion, LoFi, Ensemble, Phaser, 6 Band EQ, Compressor, Vocoder, Delay, Chorus, Tremolo, Reverb.

  • Microtuning: SynthMaster One supports Scala tuning, so tuning can be set either for each preset or globally by loading from a Scala tuning file. SynthMaster One comes with tunings analyzed from analog synthesizers.

  • Preset Browser: SynthMaster One features a comprehensive preset browser with separate search criterias for instrument type, preset attributes, music style or preset author.

    16 Step Arpeggiator/Sequencer: The arpeggiator in SynthMaster One features classic arpeggiator modes such as Up, Down, UpDown, DownUp, UpDown2, DownUp2, AsPlayed as well as Sequence, Chord and Arpeggiate modes. Each of the 16 steps of the arpeggiator has its own Velocity, Note Number, Note Length, Slide and Hold parameters.\.

  • Importing MIDI patterns as Arpeggiator Sequence: Monophonic or even polyphonic (chord) MIDI patterns can be imported into the arpeggiators in SynthMaster One by just drag and drop of the MIDI file onto the arpeggiator view on the plugin window.

A demo version of SynthMaster One is available. It is identical to the standard version except for 2 limitations:

  • Saving presets is disabled.
  • The synth starts playing random notes after 30 minutes.

This synth doesn't work for me in Cubase, all my other plugins are working fine. The thing that pisses me off is I've tried multiple times over several months to contact support including the KVR Synthmaster forum and I've never heard back from their support. I see other people on their forum saying the get no response from support also. They seem to be actively putting out updates but just ignoring any issues reported by users. So I'm stuck with a synth I paid for but can't use, kind of sucks. I can't recommend this company in any way because of the way they ignore their users. Can I give zero stars please?

Even though I'm not an EDM producer or anything like that, I love trying virtual synths and see what might fit my own audio work.

Luckily, I got myself SynthMaster One version and using it on a Windows 10 LTSB, i7 4710MQ CPU with 16GB RAM. Before I got it, I had some crackling noises and stutters on my system when using real-time processing plugins with the lowest latency possible @48 samples.

Upgrading to 16GB of RAM and also updating my GPU drivers did really help with other plugins and VSTis as well as SynhtMaster ONE. I almost had no crackling or stuttering when playing with it.

For people like creating mind-blowing sounds with synths may take a lot of time. But SynthMaster ONE comes with around 1200 something highly impressive presets.

My first impression was like it's so huge. Almost every preset sounds like it's going to dominate the sonic canvas and really gives me chills every time.

I definitely recommend anyone getting yourself a copy instead of downloading cracked software. It's very affordable and high quality in terms of sounds and tones that one can generate with this synth.

Here's a preset walkthrough that I have made with SynthMaster ONE. Including my 250 something favourite presets. Excellent job KV331! Deserves every penny :).
