Yes but each instrument has its own set of dynamics, and if youd like the muted guitar part to get gradually louder until it reaches the chorus, then the only way to do that is to make it louder in that part. One way would be splitting the track, and using different volumes on different channels, to give the illusion of the guitar changing volumes.

Id have to hear the tracks seperately to hear how they sound, it might be that some are a good fit without doing anything others, no. Same thing with ezdrums. I find that as longas you dont try to overkill it, it sounds pretty damn natrual. Then you can adjust your playing volume on the guitar or harmonica as you record.

Just trying to see how to do that with pre recorded instrument parts.
