I would love more details on this great conversion. Do the solenoids just open the valves like a roll? using the original player piano stack and vacuum motor? Please can you get in touch?
So do you just get a bunch of solenoids and position them under the keys so they pull down on the keys or do they sit behind the key shank and press up?
I cut into the vacuum lines so that the solenoids open air passages. When the solenoid opens the hole in the manifold the note sounds. It works just like the holes in the paper if you think about it. It was tricky to 3d print all the solenoid holders, make the circuitry to operate the solenoids, and then to program an arduino teensy to control it all from midi file input. It was a very fun project.

Sorry to take so long responding. I can be reached at jcmusix@gmail.com for help if you want to know more.

Probably neither since player pianos run via pneumatics

@@jcmusix1 OOh I see! That's basically how the Virtual Roll system works!
@@PiotrBarcz Well look who I found...LOL - what a small world... 😀
@@minimalizman xD
Do you have any more build details? Solenoids, interfacing to the PC etc.
I used a arduino teensy card and some circuitry to read midi data and active the solenoids. The solenoids opened air flow activating the keys.
