Logic Pro 9 Midi interface recommendations: my M-Audio midisport = 2 sec. latency


New Member
Long time legit Logic user since LAP 4. Just switched to L9. I get a 2 second delay from pushing the key down on my midi keyboard controller to hearing sound from any virtual instrument. Is it due to an incompatibility with M-Audio midisport 2x2 anniversary edition and Logic, all midisports and Logic or something I'm overlooking? Thank you for your time and help.

Two seconds is impossible under normal circumstances. There is definitely something wrong. Driver, MIDI loop, Logic, Mac, whatever. Maybe MidiMonitor helps you to find out where the delay occurs.

Do you have IAC enabled in any way? I've encountered this sort of problem (very long delay) with inadvertent IAC loops.

First thing - check this all out in a new "empty project". Second, check your physical input object in the environment and see if there are any IAC ports recognized there. Third, check your Audio MIDI setup utility. Disable IAC if unnecessary. Fourth, verify your Midisport settings there.
