New Hachi Step Sequencer for Novation Launchpad Pro + More

Hachi Step Sequencer Controlling a TT-303

Published on Dec 24, 2016 Mike Perkowitz

"Hachi runs on a Novation Launchpad Pro [+more, see below] and includes multiple sequencers. This video shows the step sequencer controlling a TT-303.

Each of the 8 columns is a step, and the note can be modified by octave (orange), velocity (green), slide (gray), tie (dark blue), repeat (pink), and so on.

For more info, see:"


A multi-function midi sequencer that runs on a Novation Launchpad Pro and a headless computer like a Raspberry Pi. Hachi is written in Java, and so can run on a Pi (tested), a Mac (tested), and many other platforms (untested), with or without keyboard and monitor.

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."


Side Note: Mike Perkowitz is the admin of the AH (Analog Heaven) mailing list, which I believe is the longest running synthesizer mailing list.
