[sdiy] GEM / GeneralMusic SX-3 service manual

[Leo Schoonbroodt]

hallo Rutger,

Did you manage to find the connection layout and working of the GEM 
pedalboard?

I own myself such a pedalboard (connected to my SX3 which is defective 
beyond repair now)
I was looking for the connection info for the pedalboard because i want 
to connect it to an Arduino microcontroller which sends then note-info 
via midi to my new keyboard which lacks a connection for such a 
pedalboard.

Any info you have managed to find would be very welcome.

Thanks for any help,
