I need to replace the CR2023 battery and then reload the presents from my laptop with a USB-MIDI cable. (There's currently no sound bank.) Korg told me that this keyboard was manufactured between 1988 and 1992. I'd love to get it working.
In the background is my good old Korg Triton LE76, which I've had since 2003. I repaired it about 2 weeks ago. I had to repair the joystick and 2nd lowest Ab. Now it 100% works. :)
I'll post another video about the M1 in the future.
