I am also having this issue. is there no way for SB to auto analyze the audio track? I use SB to do a lot of drum covers and when I put the sample track in with the tempo, its off. Even when I try to quantize the track or even change the bpm it is still off. It makes it harder to play to the metronome and then I would have to sometimes wing it and hopefully I land the marks. Is there any way to fix this?
