2099 Techno: Generative Synth

2099 Techno writes complete tracks. Press generate and you get 76 bars with an intro, builds, two main sections, a breakdown and an outro, played by a virtual-analog engine and a 909-style drum machine. Bass, acid, stabs, pad, a lead line and the kit, through a dub delay, chorus and reverb. Nothing is sampled. Every note is made on the fly and no two tracks come out the same. The music comes from chaos maths. Three Lorenz attractors shape the melody, the rhythm and the mood. Three separate logistic maps run underneath the drums, the bass and the acid line, so they wander independently: turn the logistic control down and the hats and perc repeat every bar, turn it up and they never do. Chaos on its own is noise, so a small model filters it. It gets rewarded for consonant intervals and rehearses two hundred notes over the changes before it writes anything. The CHAOS / TASTE slider decides how much say each one gets. Eight styles, and they are properly different. Detroit rolls an off-beat bass under syncopated stabs. Dub Techno holds one chord for four bars and lets the delay do the work. Acid runs a 303 line with slides and accents. Hard pushes past 140 with a Reese bass and the drive up. Minimal takes most of it away. Every track is built from its seed. Write the seed down and you can have that exact track again, note for note, whenever you want it. Turn on RADIO and it keeps playing, picking a new key, mode, style, sound kit and tempo for each track. You also get: • 8 styles, 6 dark modes, 12 keys, tempo and density • Two-oscillator analog voice with sub, noise, resonant filter and glide • 22 presets and 9 sound kits, from Warehouse to Game Boy, plus random patch • Six-part mixer, dub delay, chorus, plate reverb and a global sweep filter • MIDI in, so you can play the patch you are editing • MIDI export: six tracks, one per part • Live spectrum, waveform and a view of the chaos engine at work Two Audio Units, an instrument and a MIDI processor. Each part sends on its own MIDI channel, drums on 10, so one instance can drive six instruments. The MIDI version passes your keyboard through instead of swallowing it. Both follow your host's tempo and transport. One install registers both. The app is free and nothing in it is held back. Using the Audio Units inside other apps is a one-time purchase, and each AUv3 session plays for two minutes first so you can try them properly.
