I also used it for a Korg Poly61 MIDI-Interface - in parallel with the keyboard.

In your Korg Poly61 project, what signals were connected through the
MT8816? Did you use it to hook up to the bus going from the CPU to the
diode matrix in the keyboard? I understand in the patchbay only
digital signals were connected through this chip.

BTW, it's worth noting for anyone reading this that "8x16" means 8
horizontal x 16 vertical crossbars, and any of them can be used as
input or output.

Cheers,
