"This is Hachi, the hardware counterpart of Mike Perkowitz's open source java-based 8 module sequencer. Hachi (= ""eight"" in Japanese) can run up to 8 ""modules"" at a time. Available modules include several midi sequencers, a paint/animation toy, and a sequencer-controller that lets you coordinate your sequencers. Hachi is a generalized version of this simpler sequencer that I wrote for the original Launchpad. That basic sequencer runs as one module in Hachi. We love to be part of projects like this one"
