I am running MIDI Control Center on Windows 8 and have Beatstep Pro firmware revision 1.1.0.3 installed.
If I understand correctly, when Sync is active in MCC, changes I make to Sequencer Patterns and Project settings in the MCC should instantly update on the Beatstep Pro (and vice versa). When I make changes to Patterns or Project settings in the MCC, I see the communication arrows flash and sysex messages being transmitted in the MIDI Console, but no change occurs on the Beatstep. When I perform the same operations on the Beatstep, no communication at all occurs with the MCC. However, changes made in ControllerMap instantly update on the Beatstep as expected.
