Yeah, this project is one of the few that I work on that really needs iso. I prefer the everyone in the room approach except when its wrong for the project...
The reason we need a huge drum iso is that the drummer / percussionist switches from kit to xylo to synth trigger frequently within a piece. He's used to doing it this way live so I want to be sure he can have all the instruments set up around him the way he needs.
Many thanks to all for the ideas,
Silas
