KV331 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 a real joy. Watch our videos, listen to the audio demos and you’ll see how easy it is to design sounds with this synth.

New Features in the 1.3 Update

New White Skin by Satyatunes  The new white skin by Satyatunes is available in various sizes, ranging from 80% to 200%.

Custom Preset Attributes & Styles – Users can now add custom attributes or styles for the presets they create.

Editing MIDI Banks and Programs  Users can now edit MIDI Bank/Program assignments by launching the “MIDI Banks and Programs” dialogue.

Stereo Oscillators with Unison/Voice Stacking: Oscillators in SynthMaster have stereo output. Using the “voices”, “voices mix”, “detune curve”, “detune spread”, “pan stread”, “tone spread” and “phase spread” parameters, each basic/wavetable oscillator can generate a rich “supersaw” type sound.

Basic Oscillators – Basic oscillators in SynthMaster One are capable of synthesizing many different types of waveforms: Sine, Square, Triangle, Sawtooth, Pulse, Noise, single cycle waveforms. Each oscillator comes with 17 different algorithms in the following categories: Spectral (LP, HP, LS, HS, BP, BS), Bend (Bend+, Bend-, Bend+/-), Sync (Rect Window, Half Cos Window, Cos Window, Tri Window, Saw Window), Pulse (Pulse1, Pulse2) and Quantize.

  • Sine, Square, Triangle, Sawtooth, Pulse, Noise
  • Single-cycle waveforms

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.

Wavetable Synthesis

KV331 SynthMaster One pluginsmasters

SynthMaster One implements true wavetable synthesis which opens up new possibilities for sound design. 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.

  • Contains many wavetables
  • You can import your own wavetables by drag and drop

Semi-Modular Architecture

KV331 SynthMaster One pluginsmasters

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

  • 2 oscillators
  • 2 sub oscillators
  • 2 Filters
  • 4 ADSR Envelopes
  • 2 LFOs
  • Sequencer/arpeggiator with 16 steps

Zero Delay Feedback Filters: All of the 4 new 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!

Filter Types:

  • Ladder – Low 12, Low 24, High 12, High 24, Band Pass, Band Stop
  • Diode Ladder – Low pass 24
  • State Variable – Low 12, High 12, Band Pass, Band Stop
  • Bite – Low 12, High 6

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

  • 11 Types of effects – Distortion, LoFi, Ensemble, Phaser, 6 Band EQ, Compressor, Vocoder, Delay, Chorus, Tremolo, Reverb.
  • Flexible Effects Routing – Each of the 11 effect types can be inserted on any layer insert or on any of the 2 global effect bus inserts.

Additional Features

Some other features of SynthMaster One are listed below:

32 Step-Sequencer / Arpeggiator

KV331 SynthMaster One pluginsmasters

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.

Microtuning – SynthMaster supports Scala tuning, so tuning can be set either for each preset or globally by loading from a Scala tuning file.

Preset Browser – SynthMaster features a comprehensive preset browser with separate search criteria for instrument type, preset attributes, music style or preset author.

Importing MIDI patterns as Arpeggiator Sequence – Monophonic or even polyphonic (chord) MIDI patterns can be imported into the arpeggiators in SynthMaster by just dragging and dropping the MIDI file onto the arpeggiator view on the plugin window.

NKS Support

KV331 SynthMaster One pluginsmasters

KV331 Audio is proud to announce that SynthMaster One is now fully compatible with Native Instruments’ NKS, which give you streamlined browsing, consistent tagging, instant sound previews, pre-mapped parameters and more.

It is also compatible with M1 Apple Silicon processors which lets you run SynthMaster One on your M1 Mac natively!
