I bought Jaguar today, and downloaded 10.2.3, Logic 5.5, and the newest Midiman 2X2 drivers for my interface.

Now, no sound comes out!! The midisport isnt present, I clicked "reset midi drivers" but something is still wrong..

any help??

What do things look like in Apple's "Audio MIDI Setup" program? (In Applications/Utilities/)

It's the Command and Control center, both audio and MIDI, for all programs later in the chain.

ok! it works now... I have to go into Logic with my Midisport OFF, and then push in the button... and it works ok!
