I’ve been trying to figure out how to wire the MIDI Out (DIN) port on my 7u case to the FH-2, to serve as a DIN MIDI Input for the FH-2.
This is so I can send notes from my MPC (which has DIN MIDI out, but no MIDI out over USB) into the FH-2.
Here’s a pic of the boards from both, 7u Case on the right with Pins labelled A B C, and FH-2 on the left with Pins labelled 1 2 3 4.
The FH-2 Documentation says…:
The MIDI ports are exposed on a 4-pin expansion header (labelled GT3) on the lower PCB. All of
the necessary electronics are on the PCB; all that needs to be added is the actual sockets.
The header pin-out is as follows (pin 1 is closest to the ‘GT3’ text):
1 OUT pin 4
2 OUT pin 5
3 IN pin 5
4 IN pin 4
Pin numbers refer to the 5-pin DIN socket as in the MIDI standard.
The header is a standard 0.1" pitch header compatible with e.g. typical IDC cable sockets.
I’m curious which connections to make to get that port working as a MIDI in (i.e. 3 to X, 4 to Y).
