Well, your assertion is assuming the MIDI timing is a CPU issue and not one of a slightly off MIDI clock, or issue with the MIDI clock circuit design. Maybe that specific item could be looked into- does everyone have that same issue with the MIDI- or is something wrong with the MIDI circuit in Brooks Emax? Any comments?
