Logic Pro 9 MIDI "Panic" on save, new settings, etc.

Hi all,

I have a weird issue that is completely baffling me. When I save a new project, or go to save a new instrument in EXS, or create new settings in ES2 - or any other "new" save situation, Logic sends a barrage of MIDI output through my interface that causes my external MIDI gear to go completely nuts. It has already blown one of my near field monitors from the unexpected surge in sound. Doesn't do this to internal soft synths, just external MIDI gear.

I can see it sweep across the MIDI activity lights on my MIDI interface when I select any save operation. I have an Emagic AMT8 with the most recent drivers I could find. This did not happen in Logic 8. Any ideas? Any help would be welcome.
