I have done some work in the area of MIDI to solenoid actuation. Last year I designed a very simple MIDI to "power stuff" interface I call the WIMP. From your letter, it sounds like it would do the trick. It is made by:
Bob Baker
Electric Orchestras, Inc.
29962 N. Terre Drive
Libertyville, IL 60048
(708) 367-7996
The "computer" board is $325. If your system only requires a low current logic level input, this is all you need to control up to 64 notes. If you require some "power", then additional driver boards are needed. Each one "powers" eight solenoids, etc, and they cost $30. You will also need a separate (up to 24 VDC) power supply for your solenoids, relays, etc.
