This page was used for a brief description of the project before I published it on Instructables.com. Please view the much more detailed Instructable here: https://www.instructables.com/id/MIDI-Controlled-88-Key-Reed-Organ/
For my high-school senior project, I was going to convert an upright piano to be a MIDI-controlled player piano. However, I by chance ran across a reed organ, and knowing nothing about them became very interested in their sound and history. So I instead converted an Estey Reed organ to be MIDI operated. This is the result.
For now, just the keys are MIDI controlled. I plan on adding a vacuum motor so it doesn't have to be foot pumped, as well as control of the stops on the cheekblocks.
I am currently writing a very detailed Instructable. For now, here are some photos and some demo videos.

The completed setup in its case.
Bottom view showing the control electronics. It has been cleaned up somewhat since this was taken.
View showing how the solenoids actuate the keys.
Close up showing the popsicle stick extensions for the black keys.
Driver board, fully populated. There are a total of 6 of these.
Electronics all layed out. Solenoids are connected, as are the power wires, but the control wires from the Arduinos to the driver boards aren't.
