Nice to hear someone else is into MIDI operated calliope.  I just
received and new 53 note machine from Dave Miner.  It plays the regular
A roll and I have the UM 1 processor produced by Laurent Coray, and
hope to receive the MIDI valves from Larry Broadmoore soon.

Plans are to install several other instruments band organ style.

    25 note bell bars
    bass drum (2 beaters)
    snare drum (3 beaters)
    cymbal
    block (2 beaters)
    gong (if I can make one)

Suggestions for other options welcomed
