Who knew?

So, in answer to my question, the two mystery MIDI drum notes generated by BIAB are Hi and Low Block respectively. Problem solved. smile


I'm glad that you found the problem.

There are actually three different MIDI conventions, C3, C4, and C5. You are right in that it does get very confusing at times.

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"
