Intro to track stacks in Logic Pro for iPad
Track stacks provide a convenient way to organize and control tracks, to manage projects with high track counts, and to create and manage audio subgroups. You can create a track stack from a group of existing tracks and use the controls on the master track to control all the subtracks in the track stack.
Logic Pro has two types of track stacks: folder stacks and summing stacks. Both types have a main track and one or more subtracks. The track icon for the main track features a disclosure arrow that lets you show or hide the subtracks. When you close the stack, only the main track appears in the Tracks area.
Subtracks can include audio, software instrument, and aux tracks and can also include track stacks as subtracks.
Folder stacks
Folder stacks let you combine multiple tracks and control them as one unit, without changing the audio routing of the individual subtracks. When you create a folder stack, the channel strip assigned to the main track is called the stack master. Using the main track or the stack master channel strip, you can mute, solo, and adjust the volume level for the folder stack. This is similar to the way a Voltage Controlled Amplifier (VCA) master fader functions on a hardware mixing console.
There is no patch for the main track of a folder stack, and no patch can be saved when the main track is selected. There are no regions on the main track of a folder stack, only on its subtracks. When the folder stack is closed, the main track displays an overview of the combined contents of all subtracks.
When you mute a folder stack using the Mute button on the main track (or stack master channel strip), the mute or solo state of individual subtracks is preserved, and it becomes active again when the main track is unmuted.
Summing stacks
Summing stacks let you combine multiple tracks and route their output to an audio subgroup. When you create a summing stack, the outputs from the subtracks are routed to a bus. The destination aux of the bus is assigned to the main track. When the main track is selected, you can mute, solo, and adjust volume and send levels for the summing stack and add and edit plug-ins, affecting the sound of all the subtracks in the summing stack. This is similar to the way an audio group works.
If a summing stack contains software instrument tracks as subtracks, you can record and play MIDI regions on the main track. MIDI events on the main track are played by all the software instrument subtracks in the summing stack. You can also record and play MIDI regions on individual (software instrument) subtracks. When the summing stack is closed, the main track displays an overview of the combined contents of all subtracks.
When the main track of a summing stack is selected, you can choose a different patch for the summing stack and create your own patches. Patches for a summing stack can include the main track and all subtracks, along with their channel strip and plug-in settings. Logic Pro includes a set of patches designed for use with summing stacks.
After you create a summing stack, you can route individual subtracks to different destinations. In the Bus submenu of the Send pop-up menu on subtracks, local busses are sorted into stack submenus. Note that if you route subtracks to a destination “outside” of the stack, those subtracks are no longer affected by the controls on the main track. Audio subgroups you create are saved as part of the summing stack, and their auxes appear as the last (bottom) subtracks in the summing stack.
