Thanks for the tips. I found that the D-10 was sending out a MIDI clock because of its internal drum machine (default mode is being the MIDI master). I was able to turn that off. It still sends out a message roughly three times a second. That does seem like it is a MIDI active sense message (haven't put a monitor on it yet). Unfortunately, I don't think active sense can be turned off on the D-10. Can the BCR20000 be configured to ignore it?
