after doing soem recording from my NES & nsf players i noticed that on the following line
G# F Q12 300 400
the 300 cancels out the Q12. However, this only happenes on the NES and nsf players, not famitracker. i took out the 300 command and the note slide worked. just thought i'd point that out in case no one else had. i'm assuming it does the same thing with rxx but did not test.
