[sdiy] Behringer K-2 midi not working

If I am understanding correctly, the synth plays fine when you patch from
the K-2's own trig out to the trig In? If so, the MIDI To CV seems to be
working correctly. I think what has likely happened is that the K-2 trig
out is normalized to the trig in, but that the normal pin on the trig-in
jack has broken, so now you need to make the connection between the two
with a patch cable. This same thing has happened with other Behringer
synths like the Model D, it seems that the jacks they use might not have
very robust normal pins.
