Track Level Meter
On audio tracks, level meters indicate the level
of the signal being recorded or played back from
the hard drive. On Auxiliary Input, Master
Fader, and Instrument tracks, level meters indi-
cate the level of the signal being played through
the channel output. Green indicates nominal
levels; Yellow indicates pre-clipping (–6 dB be-
low full scale); and Red indicates clipping.
When an audio track is record-enabled, these
meters indicate record levels.
On MIDI tracks, and in Instruments view for In-
strument tracks, the meter shows the MIDI ve-
locity of the most recent MIDI event.
Pre- and Post-Fader Metering
You can globally set audio track level meters to
indicate pre- or post-fader levels. When pre-
fader metering is selected, the level meters show
levels independent of fader position. With post-
fader metering, the level meters respond to fader
position.
To toggle track level metering between pre- fader
and post-fader metering:

Select Options > Pre-Fader Metering .
