Luxium — Semi-Modular Synthesizer
Four oscillators. One living instrument. Luxium is a semi-modular software synthesizer built for expressive playing, deep patching, and sounds that keep moving after you strike a note.
Start playing. Then repatch everything.
Luxium’s normalled signal path makes a sound immediately. When you want to go further, route oscillators, filters, shapers, envelopes, LFOs, and performance controls with visible cables. Each oscillator has its own drift path and tuning controls, so a chord can move naturally without every voice tracing the same curve.
Make the signal your own
- Four oscillators with sync, pulse shaping, and through-zero FM.
- Two filter slots with 14 models, from ladders and multimode circuits to a lowpass gate and formant bank.
- 64 modulation routes and audio patching that can replace the default signal flow.
- Voice stealing, Jupiter Divide, and Re-Pedal for expressive chords and guitar-like playing.
From first note to finished tone
Shape the result with modeled amplifiers, cabinets, continuous microphone placement, a reorderable effects chain, and LushVerb. Luxium can also process external audio through the same rig.
Formats: Audio Unit and VST3 on macOS 14 or later (Apple Silicon and Intel); Windows 11 x64 VST3 planned. The public beta includes a perpetual Luxium v1 license and every 1.x update.
