I use tonelib jam just to play along with, generally, and try to assemble tab for things that don't have it, sometimes. I'm currently trying to set up to play along with a song, and I downloaded a guitarpro file that seems pretty good, but when I added the backing track, it's pretty much exactly two beats ahead of the file, which makes playing along annoying. Anyone know how to either delay the backing track kicking in by about two beats, or else have the guitarpro score kick in two beats earlier?
Go into the "Timeline" tab on the bottom, hover over the blue waveform, and you can click and drag it left or right to adjust its starting time
