PLAY-multitrack is an unofficial multitrack version of the wonderful Critter & Guitari PLAY patches for Organelle.
It keeps the sound character of the original PLAY instruments untouched and adds a four-track sequencer/looper workflow, a track mixer, bounce functions, sequence chaining, audio capture, MIDI export, and punch-in effects.
To get started, check out the README in the patch folders or here:
