Just to bother you even more.. I found a small bug.
The voices/channels used in the instrument editor for keyjazzing don't reset their pans. If you put like 19FF or 1880 in the program, it will hard pan to the right. Trigger the instrument once, then reset panning by using 1840 and triggering the sound once more. Now remove all panning instructions and keyjazz the same note many times. You'll notice one will eventually play on the right.
I know you hate me, I know.
