Bob Baker still manufactures the MC-2.  It is an add-on device that
creates a two way MIDI interface to the Pianocorder player system.
One nice feature is that no modification to the original electronics is
required.  Any music source that can output a piano part MIDI stream
can play the piano and additionally, old deteriorating Pianocorder
tapes can be saved as MIDI files.
