I've developed my own hardware and software to transfer the digital
data from Pianocorder cassettes and produce equivalent MIDI files.  I
would be happy to convert self-recorded tapes at a nominal charge for
anyone who needs this service.

I cannot supply MIDI conversions of the commercially-produced
Pianocorder cassettes.  Most of that material is now owned by Yamaha
Corporation, which currently markets portions of it in Disklavier
format.
