If you use BUZZ in liveset and use CTRL+M for muting and unmuting tracks it might be good idea to do a little edit to every song right after it is loaded and playing.
You might press CRTL+N mistakely and if there is no edits in a song you end up having blank one in the middle of live situation instead of muting track.. . .
This tip might be inaccurate some day if OT makes BUZZ update that changes this behaviour. =) - yugae
