Here's what I'd love to figure out. Let's say I have a snare track that isn't great, and I want to add a sampled snare. What I would like to do is copy the drum track to a new track, use logic's drum replacement program to map out the transients. Then split the copied snare track at each transient, so each snare hit is it's own region. Then key through the regions ( the key commands for doing this escape me ) and paste the new snare hit at the beginning of each region on a new snare track. A video on that would be a godsend for me.
