Apple Logic Pro 9 - Manual (Page 425)

• Loop: The playback of all region types can be continuously repeated by selecting the
Loop checkbox, or through use of the Loop tool. (See Creating Region Loops .)
• Delay: The playback of all region types can be delayed or advanced (this can be a
positive or negative value) by ticks, or a musical format variable; for example, 1/96,
1/16, 1/192, and so on. (For more information, see
Shifting the Playback Position of
Regions .)
• Advanced Quantization: Q-Strength: This percentage value determines how far a note
is shifted toward the nearest grid position. 100% results in full quantization; 0% leaves
the note at its recorded position.
• Advanced Quantization: Q-Range: Q-Range is a very musical quantization strategy that
requires a certain amount of technical musical prowess. It is ideal for recordings that
already have the right groove, but are too hurried or laid-back in places. It allows you
to retain the original feel, but positions the rhythmic center precisely in the groove. A
value of 0 means that every note is quantized. If you enter negative Q-Range values,
only notes that fall outside the set range are moved to ideal quantization grid positions,
while notes closer to an ideal position remain unquantized. This moves the most poorly
played notes (those outside the range) to perfect timing positions on the quantization
grid, or at least towards these positions, depending on the Q-Strength setting.
MIDI Thru: MIDI Region Defaults
If no region is selected, the upper line of the Region Parameter box displays MIDI Thru.
Any live MIDI input (in Stop mode, as well as during recording or playback) is played with
the settings chosen here. When you record a new MIDI region, the settings in the MIDI
Thru Parameter box are carried across to the new MIDI region’s Parameter box. The MIDI
Thru Parameter box can be viewed as an adjustable default Parameter box.
The MIDI Thru parameters can be adjusted when no regions are selected. Click the Arrange
window background to deselect all regions.
Note: The Set Track and MIDI Thru Parameters by Region/Folder key command allows
you to set the MIDI Thru parameters to match those of a selected MIDI region. This action
also selects the region’s track.
Editing Several Regions Simultaneously
If several regions are selected, the number of selected regions is displayed, in place of a
region name. If you alter any region parameter, all selected regions are affected. If a given
parameter is set differently in the individual regions, an asterisk (*) appears in the
Parameter field. You can alter this parameter for all selected regions, and the value
differential will be retained (relative alteration). If you want to set all selected regions to
the same value, hold down the Option key while changing the value (absolute alteration).
