I'm wondering now that Tiger has introduced Core Audio and QT7 has been released will there be good monitoring plugins for FCP. The lack of good meters as compared to whats available in ProTools LE is a major drawback of editing audio inside of FCP. The good metering plugins, (there are poor quality ones as well), are outstanding to work with . . . VU meters, Full scale, Loudness meters etc. are so valuable especially for on-line broadcast mixes.
To work in ProTools and then import your AIFF's into FCP and try to monitor levels with those wimpy meters is a bummer. I wished that was addressed in FCP 5.
