  • Anyone with Allen service manual access here? Please help with MDS-36 matrix wiring.

    I want to midify my MDS-36 that was damaged by lighting and to do this I need to know what kind of matrix the keyboards and pedalboard are wired on. Can anyone here please help?

    The pedals are 4 groups of eight.
    The keyboards are not hardwire matrixed but have parallel to serial encoders switched to ground through reed switches.
    There was also an optional keyswitch system called "Optokey." Let's hope you have the reed switches.
