Turn off tracks in Logic Pro for iPad

You can turn tracks on or off in the Tracks area. Turning a track off lets you silence the track while still hearing other tracks in the project assigned to the same channel strip. When no other track is assigned to the same channel strip, turning off a track also saves processing power because plug-ins on the channel strip are no longer processed. Turning a track off (or turning it back on) takes slightly longer than muting or unmuting the track because of internal pre-processing. Unlike muting a track, turning off a track can’t be automated.

When a software instrument track is turned off, all MIDI regions on the track are silenced, but live input (playing) is still audible.

You can also control dynamic loading of plug-ins on a track using the On/Off button. When you open a project, plug-ins on tracks that are turned off aren’t loaded, even if the tracks contain regions. While working on the project, plug-ins aren’t loaded on a track that is turned off when the track is focused, or when regions are added to the track. When the track is turned on, plug-ins are loaded if the track becomes focused. You can also make the plug-ins on a track inactive using the On/Off button.

If the On/Off button does not appear in the track headers, customize the track headers so that it is visible.
