Update: I’ve found a workaround for my audio mixer issue using HD footage @59.94 fps: If I set the RT playback rate to half, I can use the audio mixer without any problems.
Another editor here is experiencing the same issue (different Mac Pro, different RAID set, different footage) and tried the FCP 6.0.6 update but the problem remains. I had to re-install the Final Cut Studio earlier this week and am still having the same issue. Other than this audio mixer problem, the Mac Pro appears to be solid.
I must be missing something…
2 x3Ghz Quad MacPro
9 GB RAM
Mac OS X 10.5.5
QT 7.5.5
FCP 6.0.5
AJA Kona 3 (6.0.1 drivers)
G-Speed XL 12 RAID
