I'm struggling with something different.
I've found a drum riff that was recorded at 170bpm. My song is at 208bpm. The 170bpm drum riff sounds perfect if I slow it to 104bpm, but I can't insert it on the track without it sounding like it's in fast forward. Additionally, I can't slow down the track.
It would be nice if there were an option on the EZDrummer timeline to not follow the DAW between X bar and Y bar, and you could set the tempo you wanted it to play at.
