I had a MPC 2500 & OT combo for a while but I never found a means of using the two together that was satisfactory for my workflow. Ultimately I got rid of the MPC.
I’ve ordered a bunch of pads, spares & parts from MPC-Stuff over the years and they’ve always been fine. Never had to wait for anything.
