Synthesis & routingFour oscillators.
Four oscillators.
One living system.
Luxium combines a ready-to-play polysynth with the freedom to reroute audio, drive controls at audio rate, and let every oscillator age and drift along its own path.
Designed below the surface
Depth you can hear, route, and play.
The default path is immediate. The cable system opens it up: replace normalled connections, split oscillators into separate processors, create feedback paths, or use audio as modulation while notes are sounding.
independent oscillators
Layer, sync, cross-FM, detune, or route them separately. Four sources make combinations that two-oscillator voices cannot reach without stacking whole instruments.
audio inputs and tap points
Repatch filters, shapers, VCAs, noise, individual oscillators, external audio, and parallel paths. A cable cleanly replaces the normalled connection.
modulation routes
Patch envelopes, LFOs, performance controls, utilities, audio-rate oscillators, filters, and module outputs into the controls that matter.
filter models
Transistor and diode ladders, SEM, MS-20, Wasp, Prophet, Jupiter/Juno-style OTA, lowpass gate, formant, and comb structures fill two slots.
Why Luxium drift is different
Per oscillator. Per voice. Always moving.
Many virtual-analog designs apply variation at the voice level or add one global drift movement. Luxium models the smaller unit that actually wanders in hardware: every oscillator inside every voice. Four oscillators trace four independent tuning paths, with a shared environmental layer underneath. Turn Drift up and the voice blooms into a naturally changing, unison-like field without forcing every oscillator to follow the same curve.
Component-modeled character
A voice is more than a perfect waveform.
The Circuit controls reach into the behavior of the instrument instead of adding a character effect at the end. The Analog control gives each voice its own component tolerances. Drift moves every oscillator independently. Reset time, jitter, grit, sag, ramp curvature, filter drift, and saturation expose the imperfections that make physical circuits respond differently from one note to the next.
Luxium’s envelopes keep singing through voice changes: when polyphony is reallocated, the new voice inherits the current envelope level instead of dropping to zero. Jupiter Divide spreads the available voice pool across held notes and hands those envelopes across smoothly as the chord changes.
Analog and Snap envelopes
Choose asymptotic RC contours or sample-counted envelopes, then bend attack and decay with Punch, loop them, or route the free third envelope anywhere.
Jupiter Divide
One key can receive the entire voice pool; add notes and Luxium divides the pool evenly, preserving the musical handoff rather than restarting every contour.
Audio-rate modulation
An oscillator output can become filter FM, audio-rate pulse-width modulation, a sample-and-hold input, or the source for another path without a special mode.
Patch the signal itself
Audio routing is part of the instrument.
Break the normalled path
Send an oscillator around the filters, feed different sources into two filter slots, or put a shaper inside a feedback return.
Turn modules into sources
Oscillators, filters, envelopes, LFOs, utilities, and performance signals can drive the parameters around them.
Bring external audio inside
Route a guitar, drum loop, or another instrument through Luxium’s mixer, filters, modulation, amplifiers, cabinets, and reverb.
