KV331 Audio is proud to announce the availability of their award-winning software synthesizer SynthMaster 2.9 on iOS platform. As being the first app developed using KV331 Audio's new cross-platform UI framework, SynthMaster 2 runs as a standalone app or AUv3 plugin on iPads with iOS 11 and above.

SynthMaster 2 supports native resolutions of various iPad devices. User interfaces are provided for 9.7, 11 and 12.9 inch iPads in 4 different skins. Separate interfaces are provided for the AudioUnit plugin as well.

SynthMaster 2 comes with 1000 factory presets designed by world class sound designers such as BigTone, Nori Ubukata, NatLife and Yuli Yolo. Thanks to the comprehensive preset browsing features, users can easily filter presets by author name, bank name, instrument type or preset name and find the sounds that they are looking for.

There's also an IAP Shop, which lets users purchase additional sounds:

  • Desktop Presets Upgrade ($4.99): Adds all the missing presets that exist in the factory library, increasing the total factory presets count to 1950.
  • All Presets Bundle ($39.99): Adds all the 32 SynthMaster 2.9 preset expansion banks, which include 2000 presets.

Audio demos of SynthMaster factory presets are available on KV331 Audio's SoundCloud Channel

Sound Engine

At the heart of SynthMaster 2's powerful sound engine lies its oscillators, modulators, and filters.


The oscillators can operate in 4 different modes to generate sound:

  • In Basic mode, the oscillator plays single cycle waveforms or samples. With the Oscillator Unison turned on, up to 8 voices per oscillator can be played.
  • In Additive mode, 8 Basic oscillators can be stacked up to create richer tones.
  • In Wavetable mode, the oscillator can play wavetables with up to 256 frames.
  • In Vector mode, 4 Basic oscillators are mixed in 2 dimensions.


Modulators are simply basic oscillators that can be added to other oscillators or modulate other oscillators' or modulators' phases. By connecting modulators to other oscillators or modulators, complex FM tones can be synthesized.

Importing Wave Files into SynthMaster

While designing sounds, users can easily import wave files into SynthMaster 2. SynthMaster 2 can categorize those files into waveforms, wavetables or multi samples and import them accordingly.


Once the sound is generated by the oscillators it goes through SynthMaster's filters, which can operate in 6 different categories: Digital, VAnalog, Ladder, Diode Ladder, State Variable and Bite.

Custom distortion can be applied before or after the filters as well.

Modulation Architecture

SynthMaster 2 features a comprehensive modulation architecture with a wide range of modulation sources:

  • MIDI controls (ModWheel, Pitch Wheel, Velocity, Breath Controller, Foot Controller, CC74, Poly Aftertouch).
  • Macros controls.
  • 4 ADSR envelopes per layer.
  • 4 Multisegmented envelopes per layer.
  • 4 LFOs per layer.
  • 4 Sequencers per layer.
  • 4 Keyscalers per layer.

There's real-time visual feedback that lets users see how modulation sources and targets are changing when a note is being played. This is extremely helpful when designing sounds with SynthMaster 2.

New modulations can be created easily by dragging and dropping a modulation source onto a knob or slider control.

Users can easily see which controls are modulated by a modulation source by clicking on that source. Controls that are being modulated by that source will display modulation amounts. By long pressing a control, the modulation amount can be edited without the need to go through the mod matrix.


Each of the 2 layers in SynthMaster features a comprehensive arpeggiator / sequencer with 32 steps. Users can easily create sequences by recording steps one by one.


Each of the 2 layers in SynthMaster has 5 insert effect slots. 12 different types of effects can be instantiated in any of those slots. There are also 2 global effect send busses which can be used to create more complex effect routings.


SynthMaster has already been popular powerhouse synth on Windows/MacOS and it is now available on iOS with no compromise on its feature set. It is available for purchase on Apple AppStore at the intro price of $14.99 ($24.99 after September 1).
