I agree. I really enjoy the setup for an MPC where you save by programs, and each program can have its own set of samples and each track in a sequence is linked to another program. It really works well for organizing things and moving tracks between projects for preparing for a live set. The OT is problematic in that each project has its own set of samples, so you can really only have one project to pick your favorite parts for a live set up. in terms of organizing for a live performance, it is not the most convenient architecture.
