Retrigger Selected Cells or Focused Scene    ⌃⌘↩

Retriggers the selection. No need to move the mouse and click on it. Lots of new things with Live Loops.

Start and stop Live Loops cells in Logic Pro — Apple Support

Retrigger: If a cell is playing and you click it again, it starts playing from the beginning. Cells set to Retrigger can be stopped only by starting another cell in the same row, by stopping the row using the Divider column, or by stopping the entire grid.

Live Loops Grid key commands in Logic Pro — Apple Support

The following table reflects default key commands included in the U.S. factory preset.

  Show/Hide VCA

Shows or hides the VCA section on the channel strips. When a channel is assigned to a VCA it will appear in the VCA _slot_ (I don’t have a better term for it).

The VCA _slot_ is a pop-up control that will let you assign a channel to a VCA, create a new VCA, or remove the VCA assignment.

I would normally use a Folder Stack to create a VCA for several **tracks**, but that limits the ability to place those tracks into Summing Stacks.

I would use a VCA to control volume (after processing) and muting. Given the particular problems of stacks it would probably be easier to put the channels in a group and limit what actions the group does.

It really depends on what will be done with the channels.

Use VCA groups in the Logic Pro Mixer — Apple Support

Hardware mixing desks sometimes contain separate channels designed specifically to enable the engineer to submix—in other words, to route and control the signal flow of multiple channels at once using a single channel strip. Analog mixing desks often utilize Voltage Controlled Amplifiers (VCAs) in their circuitry for these submix channels, hence the name “VCA groups” for this kind of channel strip. You can use VCA channel strips to control the volume, or automate a submix, of tracks that are assigned to the VCA group.

  Nudge Region/Event Length Left by SMPTE Bit

Make the region one ‘SMPTE Bit’ longer by adding time at the beginning of the region.

SMPTE Bit was used to describe the use of subframes in previous versions of Logic.

Move regions in the Logic Pro Tracks area — Apple Support

Nudge regions by a set value
In Logic Pro, use one of the following key commands:

  Region Automation: Balance

Set the automation lane to Balance. Shows the automation lanes if they aren’t already displayed, switches from track to region-based automation, and selects ‘Balance’ as the automation parameter.

Show automation curves in Logic Pro — Apple Support

Before you can add automation points to a track’s automation curves, you need to show the automation curves. Automation curves are displayed as colored curves and points on top of audio and MIDI regions across the track, running the length of the project. You can choose whether to view and edit automation across the track (track-based automation) or only within the track’s regions (region-based automation).

Control Change Messages (Data Bytes)

8 00001000 08 Balance 0-127 MSB

MIDI Specification:

Balance

Note: Most all devices ignore the Fine adjust (#40) for Balance, and just implement
Coarse adjust (#8) because 14-bit resolution isn’t needed for this.

  Remove Fades

Removes fades from the selected audio regions. Most of the time I use region fades instead of automating fader movements. I prefer that the audio signal sent through the processing chain is at the proper level before fader movements are applied.

Delete fades in Logic Pro — Apple Support

You can delete a fade with a menu command, with the Fade tool, or by modifying the parameters in the Region inspector.
