When I boot Logic I get a box with "Core Audio - Hardware already in use - 10204". I then hit continue and everything seems to work fine, although the other day Logic crashed several times when I tried to import certain audio files. I think they were slightly dodgy files though. I've tried changing the system sound input and output to either built-in or my Igniter Card, doesn't make any diifference. Any ideas?? cheers Peter Mac G4 DP 450 MHz Logic 6.4.2 PT 6.4 Digidesign HD 1 2 x Digi HD 96 I/O MOTU MTP AV Auirora Igniter
