BCR connected directly to MKS (in/outs of both). Nothing seems to register on BCR when trying to 'learn' from the MKS.
Tried same cables hooked directly to computer's interface. I was able to send a dump to MIDIOX, and MIDIOX sends to MKS (MIDI indicator lights up on MKS when playing MIDIOX keyboard).
But changing patch/tone parameters doesn't seem to show/register anything in MIDIOX.
Still puzzled :(
