SynthMaster is a software synthesizer for music production and sound design. Its two independent layers can use subtractive, wavetable, vector or additive synthesis, making it possible to combine different tones in one patch. Modulation sources such as LFOs, envelopes and MIDI controllers can be assigned through a drag-and-drop matrix. The instrument also includes a preset and wavetable browser, an arpeggiator and an effects section.

SynthMaster is a software synthesizer from KV331 Audio for music producers and sound designers who want to build playable sounds or shape them in detail. Its two-layer design combines independent synthesizer layers in one instrument, making it possible to blend contrasting tones into a single patch. Each layer can use subtractive, wavetable, vector or additive synthesis, covering familiar synth sounds as well as more evolving textures.
Each layer can be shaped with an extensive modulation system. LFOs, envelopes and MIDI controllers can be assigned to parameters through a drag-and-drop modulation matrix, allowing movement and response to be built into a sound. With more than 650 modulation destinations, assignments can control a wide range of sound-engine parameters. This is useful for adding rhythmic motion, changing a tone as notes are played, or creating expressive patches without manually automating every control in a music project.
A library of more than 2,000 presets offers ready-to-play sounds and starting points for custom patches, while the browser helps locate presets and wavetables. SynthMaster also supports third-party preset expansions, giving users a way to add sound collections. Its built-in arpeggiator can turn held notes into repeating patterns, and the effects section provides processing options for refining a sound within the instrument. A main interface gives access to core controls, with more detailed pages available for deeper editing.
The instrument can be used for basses, leads, pads and layered textures across different styles of electronic and recorded music. Presets help with quick composition and arrangement, while the synthesis and modulation controls allow sound designers to create or adapt tones for a specific track. The two layers can be combined for more complex patches without requiring separate instrument instances for each component.
SynthMaster is offered as demo software and is intended for use as a plug-in in a digital audio workstation. The supplied Windows compatibility information includes Windows 10 and Windows 11, with 32-bit and 64-bit support; Windows 7 and Windows 8 are also listed. Plug-in format support includes VST, AU and AAX, though available formats depend on the host platform. The software is developed by KV331 Audio.
