  Set Punch Locators by Cycle Locators

Set the Punch In and Punch Out locators to the values of the Cycle locators. Sets part of a track to be recorded (during playback) of the Cycle area.

The _magic_ of digital punch-in and punch-out is hard to estimate. Just play the little section over and over again, with a new recording each time, and then _comp_ the parts together? Unheard of…

Punch in and out of audio recordings in Logic Pro — Apple Support

Punch recording is a technique you can use to overwrite a portion of a previously recorded track, during playback, without touching any of the recording before or after that portion. You punch in to interrupt playback and make the recording, then punch out to return to playback mode. You can choose between two punch recording modes: Quick Punch-In mode and Autopunch mode.

  Enter/Exit Full Screen    ⌃⌘F

How delightfully useful.

Logic doesn’t “play nice” with desktops/spaces. I avoid full screen mode because of the odd behaviors, and the difficulty of going back and forth between the sizes.

This command takes the focused window to full screen **AND** back again. A simple switch. No mousing around. So useful.

Not all windows support full screen mode, but the most useful (Arrange, Mix, Score) certainly do.

Screensets cannot keep windows at full screen. If you switch out of a full screen screenset, then back, the window will be maximized to the work area (menus and dock remain.)

  Open/Close MIDI Insert 5 Plug-in Window of focused Track

Work with the MIDI Insert in slot 5 on the focused track. Defined commands go up to MIDI Insert 15, but documentation and implementation show that there can only be 8 MIDI Inserts.

Use MIDI plug-ins in Logic Pro — Apple Support

MIDI plug-ins are inserted in software instrument channel strips and process or generate MIDI data—played from a MIDI region or a MIDI keyboard—in real time. Included are the Arpeggiator, Chord Trigger, and Modulator, along with plug-ins for transposition, randomization and other processing. Scripter enables you to create your own MIDI processing and generation scripts.

MIDI plug-ins are connected in series before the audio path of a software instrument channel strip.

MIDI plug-ins have a MIDI input, the MIDI processor, and a MIDI output. The output signals sent from MIDI plug-ins are standard MIDI events such as MIDI note or controller messages.
