ODEON MIDI Combi
(Combined Organ system)

Top: Complete for 24 notes Bottom: Additional note add on boards
This development was initiated in response to numerous requests from small organ builders, such as those creating the John Smith organ, for a compact integrated system.
But like anything I create, it grew like Topsy!
This is my most affordable complete system: an SD MIDI Player and Magnet Driver combined on a single small board.
Why use both an SD MIDI Player and a separate MIDI-to-Magnet decoder for small organs—especially when you only need to trigger a few notes and don’t require automatic registers?
MIDI note configuration must be done by MGRM; it is not user-configurable. However, as your organ expands, you can send it back to me for reprogramming. You can select the MIDI channel (1–16) that the unit will respond to, but that is the only user-configurable setting besides the number of notes.
Example: For a 32-note setup, you will need the components listed below, all included in a single kit. Each part is fully tested and pre-programmed for your organ.
