The Leopard Compatibility Thread, If it works or not Options

[lepetitmartien]

After test on the commercial version of Leopard, OS X 10.5, what's working? Or Not?

MOTU announced MachFive 2.0.1, Ethno Instrument 1.0.1, Symphonic Instrument 1.1.3 and MX4 2.1 are compatible, other software and drivers are under test/eventual upgrade.

I did a lot of upgrades in the last month. I got a new iMac with iLife '08 and then I did the Leopard upgrade.
With the "upgrade" to iLife'08. I noticed I lost all of my third party AU instruments and most third party effects. with the GB 4.1 update I was expecting those to be restored. I do now have Crystal and Automat back, but Remedy and Turntabelist are listed but don't work and And a whole bunch like Sampletank2, Linnplug don't even show up. Same with a bunch of AU effects( I Need my Monsta Chorus)
WTF? I surprised that this isn't a major headline. I've got tons of old songs that use specific AU instruments. They won't play anymore, which is really bad, if I need to go back and do a remix on a song. And I can't compose new music using instruments that I've purchased to work with GB?
Please someone tell me there's a work around, until Apple and the third parties get on the same Audio Unit page.
Oh and don't try to load a GB4 project into Logic Express 7. You'll get an error. And Logic also is having a hard time finding apple loops.

My Radium 49 keyboard ceased to be recognized with the Leopard Upgrade. But M-audio IS owned by Digi now So I expect there to be a six month lag in drivers. I hope I'm wrong 'cause having no Midi keyboard is a serious dent in any music making.
So on many fronts the GB4 and Leopard migration is a mess. I was also hoping to upgrade to Logic studio 8. Hmm, I think I'll wait a little bit
