In any case, this doesn't account for the fact that: a) Pro Tools uses the SAC quite happily on the USB interface, and b) so does Logic if you use the Logic Control emulation mode. This is a problem with Logic's SAC plug-in, or Radikal's 3.01 firmware, or both. >..if you switch SAC on after Logic startup, it "wakes up" in slave > mode, Logic recognizes it > correctly as a SAC 2.2, and and everything works fine. My SAC always wakes up in 'LOGIC (not 'LGC') mode, and there appears to be no communication between it and Logic Audio once it's started up. My understanding is that Logic has to do its initialisations etc. in order to find out there's a controller there at all. Michael, if you're reading this, it would be helpful to know what action I should take. When do you think a solution to the problem will appear? Should I be talking to Radikal too? Adrian
