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.

You can play over it, too. The pads are the notes of the track's key rather

than a piano keyboard, so nothing you touch is wrong, and the sixteen-step lane

runs in time with the track. Both play any part you like: bass, acid, stabs,

pad or lead, through that part's sound. Choose which sections the lane plays

in - just the breakdown, say - and preview it on its own without starting the

track.

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

• A PLAY panel: pads in the track's own key, and a 16-step lane with accent

and slide, running in time with the track and only in the sections you pick

• Export any track as a MIDI file, free

• Render a WAV mix, or stems - one dry WAV per part plus the mix, in a zip

• UI scale, for tablets

• Live spectrum, waveform and a view of the chaos engine at work

Plug in a USB MIDI keyboard and it plays whichever part you have selected.

Every part sends on its own MIDI channel and every drum has a note and a

channel of its own, so the app can drive external synths and drum machines.

The app is free: every track, every sound and MIDI export are yours without

paying. Rendering to audio - the WAV mix and the stems - is a one-time

purchase.
