Panther Ate My Music?, Synchronization error in Logic 6 Options

[dgrotbo]

I'm a new user (started with Logic 6 Big Box, an old Yamaha keyboard that I use as a MIDI controller and a Tascam US-122 interface) who decided to trade up to Logic Pro 7. First step was to upgrade to Panther. After doing so - I could not get any sound out of my old Logic 6 songs. I just get the error message with something about not being able to synchronize audi and MIDI tracks. It looks like Logic may not be communicating with my keyboard.

Somebody told me I need to update "the drivers." I tried updating the US-122 drivers, but still no sound. Logic seems to recognize the US-122 (it shows up in the audio preferences menu). Did Panther do something to my settings that I need to restore or do I need to reset something else. Sorry if this is a dumb question, but I did not find anything about this using the search function. Thanks for any help you can provide.

I have postponed my Logic Pro upgrade until I figure out what happened to my Logic 6 which was working just fine before Panther came along.

Thanks for the quick reply. I did as you suggested and still no go. I did notice something called "IAC Driver" in the audio midi setup file - it was shadowed (not full color) - does that mean it's not functional? Is this perhaps the driver I need to update for it to work??

Also, I am not getting any MIDI signal from from keyboard (the little red MIDI IN light on my US-122 does not light up as it used to when I press the keys).

My keyboard is a Yamaha PSR-330. The exact error message is "Error while trying to synchronize audio and MIDI."

Thanks for any help you can provide - I really appreciate the warmth of the MAC community.
