Both GearBox and PodFarm (the more important of the two) are hosed in Logic 9. Furthermore, if you try to reopen the song in 8 after saving it in 9, it, the same thing happens (kernel panic). Not sure this affects iLok users or not. I have an iLok, but my Line 6 plugins have the Tone Direct hardware as a ball an chain. Dying for a crossgrade to move to iLok instead, but they won't hear of it. PS: Thank God AND Darwin for Logic 9's guitar pedals and amps; they are filling in PodFarm's shoes rather well (better, actually, in many cases), but I'm running scared from the day I open a song with a tone I can't beat. Let us now pray. Anyway, read on for details of my misery. http://de.line6.com/community/message/53722 http://line6.com/community/message/57194 Note: some users are under the impression the issue is caused by 10.5.8. I was running 10.5.6 and had the same problem, so I don't think they are correct. Upgrading my OS did not help, of course; but it didn't hurt either. It seems to be how Line 6 plugins interact with Logic. So if your livelihood depends on Line 6, you best wait for an upgrade from them before moving to Logic 9.
