Apple Logic Pro 9 - Manual (Page 138)

• Signature/Division: The (Time) Signature display indicates the current playback or
recording time signature in a standard musical format; 4/4, 5/4, and so on. The Division
display determines the current display (and editing) resolution. A value of /16 means
that a 4/4 bar is divided into 16 sub-sections, or 4 sub beats for each beat in the bar.
• MIDI Activity (In/Out): The display indicates incoming and outgoing MIDI data. The MIDI
In display (top) will show chord names for incoming MIDI note data.
• Load Meters (CPU/HD): Click this display to show CPU load and hard disk throughput
load meters. Double-click to open the load meters as a separate window. Alternatively,
you can choose Options > Audio > System Performance from the main menu bar (or
use the Open System Performance key command, default assignment: Option-X).
Modes and Functions
The mode buttons and Master Volume slider in this area of the Transport bar are used
for several advanced recording and playback functions, including repeating project
sections, soloing, and punch recording. The buttons do not immediately trigger an action.
Rather, they switch operating states. The relevant button illuminates to indicate that the
mode is activated.
• Varispeed: Enables Varispeed mode, allowing you to alter playback speed (keeping the
original pitch) or playback speed and pitch, or to transpose classic MIDI output.
• Software Monitoring: Enables software monitoring, allowing you to process external
sources via Logic Pro effects. It also allows you to hear external sources while recording.
• Auto Input Monitoring: Automatically allows you to hear external sources at the audio
inputs.
• Pre Fader Metering: Switches all of the mixer channel strip meters between pre-fader
(the Volume fader on each channel strip) and post-fader modes (when turned off ).
• Low Latency Mode: Enables Low Latency mode, allowing you to limit the amount of
delay (latency) caused by some effects.
• Set Left Locator by Playhead and Set Right Locator by Playhead: Allow you to use the
current playhead position to define the left or right locator value.
