Keith, I've just spent hours making almost all the same observations you report! Not only that, I was doing it in the context of trying to help folks on the Yahoo group use the feature. (How embarrassing is that?) I even had the same impression as you, that it worked initially then stopped and not even a factory reset (with .pat preservation) fixed it. (I'm running Win7x64.) So I came over here to see if anyone had reported it, and lo, here's your post a couple hours young.

I will keep looking at it. But please, PLEASE PG, lose interest in midi if you must, but don't break what was already there...
