SynthMaster One

SynthMaster One is an easy to use cross-platform (Win/Mac/iOS) wavetable synthesizer with an intuitive workflow.  While it shares the same engine with its bigger brother SynthMaster, it also comes with new features like wavetable synthesis and cloud-based data synchronization. With its simple layout, rich wavetable/waveform content and inspiring factory preset library, designing new sounds with SynthMaster One is a real joy.


  • 1250 Factory Presets: SynthMaster One comes with 1250 inspiring factory presets from a world-class team of sound designers: Arksun, Aiyn Zahev, BT, Bluffmunkey, BigTone, Bulent Biyikoglu, Brian ‘Xenos’ Lee, Electronisounds, Fragment Audio, Gercek Dorman, Kevin Schroeder, Kurt Ader, Luke Neptune, Mirko Ruta, Nori Ubukata, Rob Lee, Selcuk Ergen, Vandalism, Vorpal Sound, Ufuk Kevser
  • Cross-Platform:​
    • Windows: Standalone, VST, AAX
    • macOS: VST, AU, AAX
  • 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 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​
  • 32 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 32 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. 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 or dragging and dropping them on any oscillator waveform display
  • 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 in "unison." Using the "voices," "voices mix," "detune curve," "detune spread," "pan spread," "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 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 350 scales ranging from 5 note equal tempered to 12 note alternate tunings. Users can set the keyboard mapping of the current scale to either “fill octave” or “consecutive”. The piano display highlights the notes of the scale. Under the settings tab, the scale root note and A4 reference frequency can be adjusted.
  • Preset Browser: SynthMaster One features a comprehensive preset browser with separate search criteria for instrument type, preset attributes, music style or preset author. Users can add custom attributes or styles to the browser metadata when designing their own presets.
  • Cloud-based cross-platform data synchronization: With the new cloud features, users can synchronize their SynthMaster One related data (presets, waveforms, samples, favorites, MIDI programs) on multiple machines/platforms and share their presets with other SynthMaster One users.
  • Importing MIDI patterns as Arpeggiator Sequence: Monophonic or even polyphonic (chord) MIDI patterns can be imported into the arpeggiator in SynthMaster One by just drag and drop of the MIDI file onto the arpeggiator view on the plugin window.
