In this second and last part of this series, MrCaliforniaD explains in detail how he made this keyboard out of a dead Commodore 8-bit computer and an Arturia MiniBrute keybed.
“At the end of the video, there are a few short clips of my friend playing the keyboard using different music programs.
This thing is neither a MIDI controller nor an Arduino / Raspberry Pi based design. It uses carbon contacts that act as switches and connect directly to the keyboard matrix inside a Commodore 64. Because of this, it works with ALL programs that use the C64 keys to play notes, allowing you to use a wide variety of original and sometimes rare music programs.”
