Some folks in Edinburgh have put a MIDI retrofit on a 19th-century pipe organ. There is info and video clips here. Mostly I think it’s neat that the interest in this project led to the restoration of the organi itself.

Funny slip from you.
What they really need is a service where you email them a MIDI file and they upload a multi-mic WAV recording. That would be sweet.
