WebMIDI Synth for Launchkey Mini

An experimental synthesizer made for the Novation Launchkey Mini MIDI keyboard, using Web Audio / WebMIDI.

It can also be controlled using any other MIDI controller, and with your computer's keyboard!

This is work in progress. Feedback and suggestions are welcome!

Vision

This synthesizer was developed with the aim of performing "chiptune" music live. The idea would be to have 4 musicians use MIDI instruments to perform each of the 4 monophonic channels that a Nintendo/NES can play.

You can read more about that project, there: adrienjoly.com/chips
