Record Enabling Tracks
To be able to record, you must record-enable the tracks on which you want to record.
To record-enable a track, activate Record Enable in the track list, in the Inspector, or in the MixConsole.
To record-enable all audio tracks simultaneously, set up a key command for Activate Record Enable for all Audio Tracks in the Mixer category of the Key Commands dialog and use it.
To record-enable audio or MIDI tracks on selection, activate the Enable Record on Selected Audio Track or the Enable Record on Selected MIDI Track option in the Preferences dialog (Editing—Project & MixConsole page).
The exact number of audio tracks that you can record simultaneously depends on your computer CPU and hard disk performance. Activate the Warn on Processing Overloads option in the Preferences dialog (VST page) to show a warning message as soon as the CPU overload indicator lights up during recording.
