mastering, a sequencer, a song arranger and a live rig.

ADEF MULTI POLY SYNTH · V1.1
ADEF Multi Poly Synth
A synthesis method specified in 1990 and finally built. The patch is an equation — and you write it, any equation you like, with the card rebuilding itself around what you typed. Around that: an 8-slot multitimbral workstation with 14 methods, the UNIQUENCER per-step effect sequencer, MATCH EQ mastering, a sequencer, a song arranger, a live rig, and an Ensoniq-format sample player.
SYNTH — wire an instrument from units, and read back the equation you just builtPERFORMANCE — eight instruments at once, with zones, mix and routingSONG — clips, automation lanes and a full mastering chainLIVE — what is playing, on which track, right nowEFFECTS — four buses, with AU/VST3 plugin inserts on FX3 and FX4SYSTEM MIDI — clock, sync and hardware routing
AU + VST3 PLUGIN · FREE · MAC + WINDOWS · V1.3
ADEF Player
Plays ADEF patches in your DAW — the ones you build free in the browser, and the ones the Mac app makes. Logic, Ableton, Reaper, Cubase, FL, Bitwig, GarageBand. Inside: the UNIQUENCER per-step effect sequencer, arpeggios, host tempo sync, half and double time, editable unison, five stereo outs (Main + FX1–FX4) and a sidechain input. Every wave and texture is baked into the binary, so there is no library folder to install.
FREE
No sign-up, no strings.
Universal — Apple Silicon and Intel, one download. Signed and notarized by Apple.
Build a patch free at the ADEF web generator, download it, and hit LOAD in the plugin. The Mac app above is where you build them by hand, arrange them and mix them.
The Windows ZIP includes 7 presets and 18 UNIQUENCER patterns, so it makes a sound without a second download.
