Quite an amazing piece of machinry... Actually the plan is for the touch screen to have various composers or types of music and under each composer or music there would be titles. As titles are sellected they would be listed in a que and begin to play one at time. I would have Play, Pause, stop, cancle, etc...
The Harpsichord plays by a bank of solenoids driving the notes. The solenoids are driven by a midi interface board, and the ML computer gives a midi output to the midi board. ML will need to be able to start a sellected midi file when requested and keep track of a play list as items are added or subtracted.
I actuall want it to also play a tune when I enter the house as a welcome. This would be conditional response to my entry as I do not want it to play if it is late and my wife is sleeping.
