  Cycle Through Window Views    ⇥

Only in the main window. The TAB key. Changes the focus between the various areas in a window. Movement is clockwise. In the main window you get Tracks, Lists, Mixer, and back to Tracks. Shift-TAB reverses the order, counter-clockwise.

Logic Pro 9 User Manual: Understanding the Window Types

The Arrange window can incorporate several other windows in different areas. These can be given key focus by clicking the background or title bar of the window (the area of the Arrange window you want to use), or by using a tool in the window.

Tip: You can also use Tab or Shift-Tab to cycle through the Arrange window areas: Tab cycles forward, Shift-Tab cycles backward.

The main characteristic of the key focus window (or area of the Arrange window) is that key commands only affect this window, and not any of the others.

Open and close windows — Logic Pro X

Only one window can have key focus at a given time, this is called the active window. When several normal windows overlap, the active window is the window in the foreground. The title of the window with key focus is black (the titles of other open windows are gray). Inside a window, the area with key focus (for example, the Tracks area) is bordered by a blue frame.

  Region Automation: Control Change 23

Program MIDI Control Change 23 for the selected region.

Drawing in MIDI CC messages using Region Automation can be far simpler than trying to insert events in the event list or adding them in the Step Editor.

Music Programming 301.

MIDI CC23 — called Control Change in Logic — is an undefined Continuous Controller. CC23 contains the MSB (most significant bits) of the control value. MIDI CC55 contains the LSB (least significant bits) or “fine control” values.

Control Change Messages (Data Bytes)

The following table lists all currently defined Control Change messages and Channel Mode messages, in control number order (adapted from “MIDI by the Numbers” by D. Valenti-Electronic Musician 2/88, and updated by the MIDI Manufacturers Association.) This table is intended as an overview of MIDI, and is by no means complete.

Show automation curves — Logic Pro X

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).

  Snap Automation Mode: 1/64 Triplet (1/96)

Events and time. The abstraction of note duration and interpretation is intriguing. I have seen 64th notes (hemisemidemiquaver) in scores, but I don’t think I’ve ever seen a 64th note triplet. The abstraction tends to break down about this point in the mapping. This is the point where I would be switching to SMPTE frames for alignment.

Snap automation to grid positions — Logic Pro X

You can snap track automation to grid positions. You can choose if you want automation to automatically use the division value chosen in the Snap menu, or you can choose a different snap value for automation.

⇧ SHIFT – ⌃ CONTROL – ⌥ OPTION – ⌘ COMMAND

While I was chasing down hemidemisemiquaver I read a bit about 128th notes on Wikipedia. This little gem was in the first paragraph. Hmmm.

Since human pitch perception begins at 20 Hz (1200/minute), then a 128th-note tremolo becomes a single pitch in perception at = 37.5 bpm.
