Assign To Exclusive Group: 7 — Logic Pro keyboard command of the day (KCotD)

  Assign To Exclusive Group: 7

Assigns a drum pad (Drum Machine Designer) to exclusive group 7. The best example is in the documentation where they describe the hi-hat as a group of 3 sounds.

Exclusive Group: Choose a group for the pad. You can assign multiple pads to the same group. As soon as one drum sound in the group is triggered, all other sounds in that same group are stopped. For example, you could group three pads with open, semi-closed, and closed hi-hat sounds. Only one of these sounds can be played at a time, mirroring the behavior of real hi-hats.

New Arpeggiator — Logic Pro keyboard command of the day (KCotD)

  New Arpeggiator

Create a new Arpeggiator object in the MIDI Environment (Logic Pro Environment).

I suspect that I will never use the Arpeggiator in the environment opting to use the Arpeggiator MIDI plugin instead.

Arpeggiators in the Logic Pro Environment — Apple Support

An arpeggiator object turns chords into arpeggios. It plays the currently held notes—individually—in a selectable pattern (up, down, random, and so on), and at a selectable speed that ranges between whole notes and 768th notes.

You can use the Arpeggiator MIDI plug-in with the Smart Controls on a software instrument track. When you turn on the Arpeggiator, chords you play on the keyboard are arpeggiated, or played one note at a time rather than simultaneously.

Select Playing Cells — Logic Pro keyboard command of the day (KCotD)

  Select Playing Cells

Select all of the cells that are currently playing. I can imagine using this command to prepare to completely stop a Live Loop playback.

Edit Live Loops cells in Logic Pro — Apple Support

Parameters for selected cells appear in the Cell inspector, which replaces the Region inspector when cells are selected. When you select a single cell, the title bar of the Cell inspector shows the cell name; when you select multiple cells, the title bar shows the number of selected cells.

Logic Pro 9 User Manual: Using the Sample Editor’s “Time and Pitch Machine”

Using the Sample Editor’s “Time and Pitch Machine”
You can use the “Time and Pitch Machine” to radically alter the time structure of audio files, including time compression or expansion, and pitch transposition. When changing the pitch, you can also correct any alteration of the formants—the vocal characteristics of the pitch-shifted audio. Pitch shifting without formant correction causes a phenomenon commonly known as the Mickey Mouse effect.

In the “Time and Pitch Machine,” time and pitch functions can be carried out together, or can be performed independently of one another.
