KV331 Audio Synthmaster One

What SynthMaster One Is For

SynthMaster One is a virtual instrument dedicated to electronic music production and modern sound design. Thanks to its wavetable synthesis and versatile oscillators, it allows you to quickly create solid basses, cutting leads, evolving pads, plucks, and animated textures while remaining easy to use. It is suitable for beatmaking, film music, live performance, or studio composition, with a results-oriented approach.

With its 16-step arpeggiator sequencer and large preset library, SynthMaster One is also an excellent choice for quickly starting a track: load a sound, play, then refine with filters, envelopes, and effects to perfectly integrate it into your mix.

Main Features

Wavetable Synthesis and Import

SynthMaster One emphasizes true wavetable synthesis, ideal for obtaining rich, animated, and very contemporary timbres. You can import audio files containing wavetables and expand your sonic palette by adding your content to the software's Waveforms folder. The result: moving sounds, expressive harmonic sweeps, and evolving textures suited for modern productions.

Two Stereo Oscillators and Massive Unison

The engine revolves around 2 oscillators with stereo output, complemented by 2 sub oscillators to reinforce the low end. Each oscillator can have up to 16 voices of unison for wide pads and dense supersaws. Spread parameters (voice mix, detune curve and spread, pan spread, pitch spread, phase spread) allow precise sculpting of stereo width and sound thickness, from clean to aggressive.

The basic oscillators cover classic waveforms: sine, square, triangle, sawtooth, pulse, noise as well as single cycle waveforms. They also include 17 transformation algorithms divided into Spectral, Bend, Sync, Pulse, and Quantize families, enabling quick shifts from simple timbres to more complex sonic signatures.

Musical Filtering and Effective Modulation

SynthMaster One includes 2 filters with several models suited for electronic styles: 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), and Bite (low 12, high 6). For animation, you have 4 ADSR envelopes and 2 LFOs, perfect for adding movement to wavetables, filters, pitch, or effects.

16-Step Arpeggiator Sequencer

The 16-step arpeggiator sequencer facilitates creating rhythmic patterns, ostinatos, and syncopated melodic lines. It's an effective tool for turning a simple chord into a groove or achieving patterns typical of EDM, synthwave, techno, pop, and electro styles.

Built-in Effects for Mix-Ready Sound

The effects section (a total of 11 processors) allows you to finalize the sound directly inside the instrument: saturation and distortion for impact, LoFi for grain, chorus and ensemble for thickness, phaser and tremolo for movement, delay and reverb for space, vocoder for vocal textures, compressor for dynamic control, and 6-band EQ to position the sound in the mix. This integrated chain speeds up workflow and avoids multiplying external plugins.

Cloud, Tunings, and Ergonomics

Cloud synchronization enables aligning your content across multiple machines and platforms: presets, waveforms, samples, favorites, and MIDI programs. This is especially convenient if you switch between studio and laptop computers. The software also offers enhanced microtuning functions, with keyboard mapping options (fill octave or consecutive), highlighted notes on the piano-style display, root note adjustment, and A4 reference frequency tuning. Finally, the interface features a white skin available in multiple sizes, resizable from 80 to 200 percent to suit your screen and comfort.
