John, I almost never use a canned intro. I am talking about playing thru an ending. If you are playing voicing that uses the ensemble function (assume a sax trio), on the first beat of an ending 1 all the harmony notes abruptly end. It doesn't make sense to stop playing at the first beat of the ending and a solo sax at that point doesn't sound right.

I do not have Single Touch on.

It's not a big deal for me. I don't like long canned endings anyway. I'm finding that ending 2 works great for me even when I'm not using the ensemble function.

I'm almost certain Dave is right. I am finding drop-outs occasionally when I am playing complex voicing with a rhythm.
