Autumn Leaves - A piano improv on a Launchpad Pro & with an Arduino

Published on Nov 10, 2018 Lanthan O'Ide

"Just a little piano improvisation, but played on a Launchpad.
I hope you'll enjoy it! ^^
Since realistic piano playing is hard without a sustain pedal, I built my own custom MIDI controller.
With it I can attach a sustain & expression pedal to any MIDI controller.
Pretty neat, huh? ;-)

It has a MIDI input and output, and two pedal inputs.
The Arduino Uno inside it just passes any MIDI messages from the input to the output,
and also sends CC messages if a pedal has been pushed or released.
So I can just put it between any keyboard and synth.

The four buttons & lights on the right specify the MIDI channel for the pedals.
(In binary, of course ;-) )

The LED on the left lights up when a sustain pedal is pushed down."
