hachi

Euclidean drum machine emulating the TR-808 sound.
I’ve written this script to learn Lua, SuperCollider and the norns environment.
The sound engine is based on the SC808 by Yoshinosuke Horiuchi.
I have implemented only my favorite sounds, to keep the GUI in a single norns page. The sequencer borrows some techniques from playfair euclidean drummer written by @tehn with new features (randomizer, real time recording).
