SynthMaster One Wavetable Synth For iOS Now Available

KV331 Audio has introduced SynthMaster One for iPad – the mobile version of their SynthMaster One software synthesizer.

SynthMaster One for iOS is identical feature-wise identical to the desktop version, with these exceptions:

  • 16 voice polyphony (32 for the desktop version)
  • Up to 2x oversampling (4x for the desktop version)
  • Comes with 500 presets (800 for the desktop version)

We’ve embedded the official intro videos above.


  • 500 Factory Presets: SynthMaster One iOS comes with inspiring factory presets from a world class team of sound designers: Arksun, Aiyn Zahev, BigTone Studios, Bluffmunkey, Bulent Biyikoglu, Gercek Dorman, Dejavu Sound, Nori Ubukata, Rob Lee, Ufuk Kevser, Selcuk Ergen, The Machine, Vandalism Sound, Vorpalsound and Xenos Soundworks
  • AUv3: SynthMaster One iOS supports AudioUnits V3, allowing multiple instances to run under supporting DAW apps like GarageBand, Cubasis or Beat Maker. It also supports parameter automation and full screen when running inside GarageBand.
  • AirDrop: Easily share your presets over AirDrop, Mail or other iOS Applications. SynthMaster One iOS presets are interchangeable with the desktop version.
  • Semi-Modular Architecture: For each SynthMaster One instance, there are 2 oscillators with 2 sub oscillators, 2 Filters, 4 ADSR Envelopes, 3 LFOs, a powerful 16 step arpeggiator/sequencer and also 11 different effects 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.
  • 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.
  • *Wavetable Synthesis: SynthMaster One implements true wavetable synthesis which opens up new possibilities for sound design. SynthMaster One comes with a rich wavetable library and you can extend that by dragging and dropping wavetable files using the Files App (requires iOS 11+)
  • 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.
  • Zero Delay Feedback Filters: All of the 4 filter categories in SynthMaster One 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.
  • Preset Browser: SynthMaster One features a comprehensive preset browser with separate search criterias for instrument type, preset attributes, music style or preset author.

  1. Those KV331 softsynths are a unique thing. In some ways, they’re really good on paper, hitting all the right notes. Wavetable, MPE, AUv3, drag and drop, extensive modulation… Like a dream come true. And less expensive than the competition. This one is almost the Serum for iOS.
    But… No offence to Bülent or anyone else on that team… It’s just that these synths are in constant “work in progress” mode. The roadmap is a bit clearer now thanks to some forum comments made by the aforementioned Bülent. For instance, SM3 is going to come much later than expected. In the meantime, though, each synth has a fairly long list of outstanding issue most of which sound like they come from narrow testing.
    Of course, our Turkish friend can quickly come out with a fix or three. Version 1.0.3 was released tonight and it boasts a new feature as well as two bug fixes. But several of my own pet bugs haven’t been fixed. Sure, it’s still a cool synth. Beats many other offerings in terms of breadth. A few of the presets are fine, if you like that kind of thing, and the real power resides in editing your own patches. Good value for the money.
    But, to be honest, it’s far from a premium experience.
    There’s also a dearth of documentation at release date (Bülent thinks videos can fill the gap but he claims there will be an actual manual. Hopefully, we’ll be able to download the PDF, unlike SynthMaster Player’s). It’s a fairly deep synth and things like Wave Index Spread require more explanation than those strange “Multiplier” video tuts, somehow labeled as “reviews”.

    If only KV331 could hire a few people to do a bit of QA, some others to do bug fixes, maybe a community manager or two, and free Bülent to work on the core code… maybe then we could get as robust a product as Xfer Records’ Serum is said to be. (Never tried Steve Duda’s flagship softsynth but my guess is that it isn’t plagued with as many noticeable bugs and issues as in SynthMaster 2.9 for macOS and Windows or SynthMaster One and SynthMaster Player for iOS, macOS, and Windows.)

    Again, no offence to anyone involved.
