[sdiy] Korg M1 keyboard wiring

[Bruno Newman]

Hi Tom - I have recently disassembled and fixed my M1 and was surprised to see the keybed was identical to the Yamaha SY-77 which I was refurbing at the same time. Not sure if that helps, but it spreads the net wider!

Best,

Bruno

    Thanks Charlie!

    For some reason, I’d assumed there wouldn’t be a service manual flying about for something like this. I suppose I still think of the the M1 as “recent”, although it’s thirty years old now.
