Alright you guys, I'm convinced! Just seeing the parts separated in the arrangement is huge. I'm going to do separate drum racks in a group from here on out!
That said, I couldn't stand loading in an 808, only using one pad, and leaving the rest of the samples and corresponding chains there to rot. I'd have to think it sucks up CPU, or at the very least, makes your pack too big when it's time to archive the project.
