Disabling Tracks
You can disable audio, instrument, MIDI, and sampler tracks that you do not want to play back or process at the moment. Disabling a track zeroes its output volume and shuts down all disk activity and processing for the track.
Procedure
Right-click in the track list and select Disable Track from the context menu.
Result
The track color changes and the corresponding channel in the MixConsole is hidden.
To enable a disabled track and restore all channel settings, right-click in the track list and select Enable Track.
