To do it properly you'd need to extract clock pulses, start, stop and continue from your MIDI - which would either require more circuitry, or a processor of some kind. I can't make out what chips you've got in there... so if you are using something programmable already, ignore me!
The converter is built around Colin Fraser's excellent m2d2m source code (found here), which was compiled and programmed to a PIC12F629 microchip. So yeah, it decodes the MIDI stream and listens exclusively for the start/stop/continue codes
You know, I think I'm just gonna build a few and throw them up online. I'll post links when I have something to sell.
