Hm, that's strange and disappointing. I really thought I'd found the cause there. > TEST1: Nine tracks with patterns all playing to different channels > from #1 to #9 on the same external instrument.

Well, comparatively perhaps -- but that actually seems really high to me already. > TEST3: Similar to TEST2 in that all 9 tracks are on the same > device/instrument channel #1.

This is the strangest one to me. > Something about being on the same channel? All the blinking meters on > empty tracks? That is a puzzle. I will investigate those meters, since they're the only GUI element that differs between the two examples (right?)... it would be odd if they were the cause, but it's not impossible.
