R12???

[djiceman]

After my problems with my first attempt with the midibox 64 core, im making a core with the features that I need. So i removed j4, j15, j10, j13 and j12 along with the optocoupler and the trimpots.

What is the function of R12? its not shown on the schematic?

I changed a few things around and made the traces more easier to work with in some places.

R12 is just a pull-up resistor, You don't need it unless you are using a IIc_MIDI module.

It is shown on the schematic, Near J4.
