Emagic have posted an update for Logic Pro 6.4.2 at
Emagic - Download site

This version simplifies the license management on the XSKey and fixes a few problems in the Mac OS X version.

In detail:
- OMF import and export is significantly improved.
- The Autoload song loads now as expected when its name contains the extension “.lso” or the launch of Logic Pro is interrupted by a warning dialog (e.g. authorization request from an AU plug-in).
- Improved support for AU plug-in tempo synchronization. - Crossfades which are created with the crossfade tool in the Arrange window are now using “equal power” as defaultfade form.
- Unused controls on control surfaces no longer create unwanted MIDI events.
- Improved sample rate switching for certain audio drivers (e.g. for LynxTwo cards).
- Further improvements in different areas of the application.

Have fun,
Ben

What's the upgrade path from 6.3.1 to 6.4.x?

I upgraded from 4.x after waiting quite awhile. Now the only difference between everythng I have is the dang "Space Desigener" verb. It sounds nice but I don't know that I want to drop half a grand for a verb plug-in.

Holler back.

Hey there, Phil! Jt Oaks here. I recognized yer name, town and lingo in the post and thought I'd give you a holler. I don't know much of nothin' about your question, but I just wanted to say howdy. So, howdy. Let's catch up sometime! Talk to you soon.

Phil,

To upgrade you have to buy the Logic Pro upgrade. Logic Pro = V6.4

Phil,

I just read somewhere else that you can install the 6.4.2 upgrade over 6.3, using your existing xs codes. You won't have SpaceDesigner then, but your other plugins should still work.

I haven't tried it myself though as I already had the Pro update, so beware....
