The overall Chordset dimensions are 5 3/4 for width and 6" for depth. Keys are spaced like regular piano keys, whatever that is. That should help you dimension the drawing you have. We found very few programs that would use it. Marc

Anyway I was wondering if it would be possible to get some accurate and detailed scale measurements of the Alto chorded keyset? There is a plan drawing of the in the keyset in the Alto docs but it has no dimensions. I've had an idea for some time that a 3D-printed exact replica would be a fun project for a PC, with something like an Arduino Nano or Pro Mini tucked inside. Steve.
