An analog-style software synthesizer with four oscillators, component-level behavior, deep cable routing, and a complete studio and guitar effects chain.
The unlicensed demo adds periodic vinyl crackle after 15 minutes. The download page explains installation and system requirements.
Beautiful sound · a brighter tomorrow
Analog behavior, modeled from the inside.
01
Four oscillators, four lives
Every oscillator can run its own waveform, tuning, through-zero FM, sync, pulse shaping, and continuously moving drift path.
02
Repatch the instrument
Replace normalled audio connections, cable module outputs into modulation destinations, and reshape the signal path while notes are sounding.
03
Finish the sound inside Luxium
Move from synthesis into modeled amplifiers, physically responsive cabinets, continuous microphone placement, and LushVerb without leaving the instrument.
One instrument · several creative worlds
Capabilities that usually live in separate tools.
Analog behavior with movement
Per-voice component tolerance and per-oscillator continuous drift create variation within a note, across a chord, and over a performance.
Modular audio, ready by default
The normalled signal path plays immediately. Patch cables can then replace audio connections, create parallel paths, and turn module outputs into modulation.
A guitar-grade effects path
Modeled amplifier circuits, continuous mic geometry, physically scaled cabinets, and a reorderable effects chain make external audio part of the instrument.
A reverb with its own identity
LushVerb shapes Luxium's combined sound with ten algorithms, shimmer, chorus motion, randomness, ducking, freeze, and a rich moving tail.
Why Luxium exists
I spent years looking for this instrument.
It did not exist, so I built it.
Filter 1, Drive 6.37×
I wanted an analog-style synthesizer that behaved like the classic polysynths: real voice stealing, where a stolen voice hands its envelope level to the incoming note, the behavior some instruments call singing envelopes. I wanted it to play like a guitar too. A guitar string re-triggers the same note without stacking on top of itself, so you can hold a chord with the sustain pedal and strike it again and again through a distorted amp and the notes never pile up. I wrote custom scripts around other synthesizers, including Reason’s Thor, to approximate that, and none of them gave me the behavior I was after. In Luxium it is a switch called Re-Pedal.
I also wanted the modular side. Audio cables plugged into modulation inputs. Filters and effects I could swap and wire in different orders. Module inputs I could overdrive, so that pushing a filter or a shaper past clean gives rich harmonics and a real edge. And I wanted a proper guitar effects chain in the same instrument, with distortion that sounds good.
No product combined those things. Some had two of them; none had all of them together. After years of searching and wishing, I decided to build it myself, because I am a software engineer and that was the one thing I could do about it. Luxium is that instrument.
This early offer is for musicians who want to explore Luxium, report what they find, and help shape the workflow, sound, and capabilities of v1. The price will rise as Luxium matures, and we cannot guarantee how long the current promotion will remain available.
