euxy
A generative euclidean sequencer for the Teenage Engineering OP-XY, on your iPhone over USB-C MIDI.

Lo-Fi Bounce
4 LANES · 76 BPM
The app sends MIDI over USB-C to play patterns on the OP-XY itself. The sounds here are synthesized in the browser as an example.
Rather than placing beats one at a time, you tell a lane how many hits to fit into how many steps and it spreads them as evenly as it can. Changing one number lands you on a different groove — so you find rhythms by dialing rather than drawing, including ones you wouldn’t have programmed by hand.
PER LANE · 2 GENERATORS (PULSES + ROTATE) · COMBINE OR/AND/XOR/A>B · TRACK ROTATE · 1–64 STEPS · NOTE · OP-XY TRACK · VELOCITY · GATE · RESOLUTION — LANES OF DIFFERENT LENGTHS DRIFT INTO POLYMETER
This is mainly for jamming without the hardware: euxy on iPhone sequences, and this page — open in a desktop browser — becomes the speaker, over a USB cable. Live MIDI input lands here in a later update; today the presets above play standalone.

Every euxy pattern can be shared as a QR code. Scanning one opens the pattern in the app — or, without the app, plays it on this site. No server, no account: the whole pattern lives inside the link.
