Bug reports & end-user support for Akai's MPC Software 'controllers' including the new MPC Studio 2, the MPC Touch, MPC Renaissance & original MPC Studio and MPC StudioB lack.
Could well be. Have you tried the same thing lowering your bit rate to 16? If I remember that right, some equipment doesn't support S/PDIF over like 20 bit or something.
EDIT: I generally don't use 96 kHz, since some of the outboard stuff I use doesn't support it. No bother to test that right now. Sorry!
