MIDI Piano Roll Decoder Prototype

This prototype board reads a standard 65-note piano scroll and sends out MIDI data in realtime. A bank of 65 infra-red emitters and detectors are used to read the scroll.

The roll used here is Kastner&Co. 10270 - Maritana Overture, Wallace and is being played through the Native Instruments B4 synth.

A smaller part of a much bigger project in the works...

I am too, this seems like it could be a nice portable way to play rolls without a player piano.

Have you been able to make one for an 88 note roll? I am seriously interested!

No, don't run it through the pianola, figure out it's rpm's and build one. Regardless of whether or not ou do that though, still AWESOME JOB

Looks like the project is coming through well.

As a suggestion, if it's possible, try feeding it into the pianola roller to get a steady tempo. Then again, I don't know if you have a working one.
