Either a computer-controlled continuously variable leak (based on the 128 expression levels), or else a series of graduated holes (like, 8 correctly graduated holes opened in various combinations produces 64 expression levels) will set the expression level.

I know pneumatics kick solenoid's butt any day of the week, also for safety reasons. What I meant is a custom pneumatic stack, with each valve isolated from the main supply via it's own pouch regulator (hickman style), which can be made small since it is only regulating the expression of one note.

My Midi conversions convert a regular Player Piano to play MIDI files. I also can convert Duo Art and Reproducing piano's in which do have expression. The Disk systems that are out there use there own solenoids that push the keys that are "post modulated" and therefore you can set the expression. Converting the original Player Piano Stack operates much better that adding a Disk System using the push solenoids. The original stack has a much better repetition than the push solenoids can produce.

Nice arrangement. Does your instrument have any expression controls on it? It would be cool if someone could design a stack that has separate expression for each note, kind of like the Kaster Kastonome or the Solo Apollo. Since, after all, MIDI coding already codes for separate expression for each note (I think).

When this video was taken the piano was just tuned. Must be the video.I have a Midi operated Nickelodeon working, just needs instruments added. Have to add new pictures and info to my website. You can check it out under the " Gulbransen conversion". Thanks for watching. Robert
