midi controller board and guide for building a vpo based on a Conn 650 theater organ. Analog organ midicizer compatible with Grandorgue (and likely Hauptwerk) - socphoenix/pico-midicizer

The only organ to pop up in our town in the last 3 years with a full pedalboard was a broken Conn 650. Using under $300 in parts I’ve built a midi controller to connect to GrandOrgue (or Hauptwerk) that covers all three manuals, pedalboard, 12 generals, and toe studs made from guitar stomp box buttons and wooden half balls.

I just finished adding the toe studs and thought this community might appreciate the project!
