6. If the Arm Recording button is on, the track is record-enabled (page 205). With multiple
tracks selected, pressing any of their Arm switches will arm all of them. Otherwise, tracks
can only be armed one at a time unless the [CTRL](PC) / [CMD](Mac) modifier is held
down or the Exclusive Arm option in the Record/Warp/Launch Preferences is deactivated.
With Exclusive Arm enabled, inserting an instrument into a new or empty MIDI track will
automatically arm the track.
15.1.1 Session Mixer Features
The Session Mixer’s Possibilities.
The Mixer section of the Session Mixer has several additional features that are not visible by
default. The mixer is resizable, and dragging upwards on the top of the mixer will extend the
height of the track meters, adding tick marks, a numeric volume field and resettable peak level
indicators. Increasing a track’s width in this state will add a decibel scale alongside the meter’s
tick marks.
These enhancements are tailored for use in traditional mixing settings, but are available anytime
the Mixer section is displayed.
Because of the enormous headroom of Live’s 32-bit floating point audio engine, Live’s meters
can be driven far “into the red“ without causing the signals to clip. The only time that signals over
0 dB will be problematic is when routing to or from physical inputs and outputs, like those of
your sound card, or when saving audio to a file.
