Trellis Speaks MIDI: Early August 2014

HUGE MILESTONE – Trellis Pad Works as a MIDI sequencer… AKA NOTES ARE BEING PLAYED!

WOO!! So what’s going on here? The Trellis is plugged into an Arduino Leonardo, which is hooked up to my computer via USB. The Trellis sends information to the Leonardo based on buttons that are activated (pushed once); if a button is active, the Trellis will tell the Leonardo to send a MIDI message, corresponding to that button’s position, to the computer.

MIDI is essentially the language digital instruments use to communicate with a computer and ultimately play a sound. All electronic keyboards use MIDI to play notes.

Logic Pro X, basically a pro version of the music-making software Garageband, uses the MIDI message sent from the Leonardo to have the selected instrument play a note. In other words, pushed buttons make sounds play from music-making software on a computer. Awesome.

We’re getting close. Time to go full scale.
