Midi Retrofitting a Rhythm Ace FR-2L with Arduino


Title says it all.  You'll find full details on how to do the mod at Youth Vulture here.

Some interesting synth history/trivia from the post's intro:

"In the late 1960s, Japanese company Ace Tone released the first ever rhythm machine to use transistors to generate its tones. This machine was called the FR-1, and its design influenced nearly every drum machine produced until the digital machines that started cropping up in the early 80s. A few years after the FR-1, Ace Tone put out the FR-2L, an organ-top version of the FR-1 which is identical on the inside, save for a few arbitrary differences. In fact, the circuit boards inside my FR-2L even say FR-1."
