This plywood board I found turned out to be the perfect width for my two-octave piano I was planning to build.

This is a more intuitive build, mirroring a piano setup. I added four midi CC controllers for use in Ableton Live.

I am using the Arduino MEGA for this build because it has a lot of digital inputs which I need for all the buttons.

This uses a similar wiring scheme at the Midifighter so it was a slightly quicker build.

I decided on a long and skinny look for this one, experimenting with form and aesthetics guided by function.

Both of these can be played through separate channels simultaneously with Ableton Live or any other Digital Audio Workstation.
