Logic Pro for iPad audio region parameters

When one or more audio regions are selected, the following audio region parameters are available in the inspector.

General audio region parameters

Name field: Shows the name of the selected region. Tap the name, then enter a new name. When multiple regions are selected, the number of selected regions appears instead of the region name.
Color: Tap to open the Colors palette, then tap a new region color in the Colors palette.
Mute switch: Tap to mute the selected region or regions to exclude them from playback.
Loop switch: Tap to loop the region continuously until the next region on the track. See Loop regions.
Gain: Drag vertically to set the gain for the audio regions in decibels; or tap, then edit the value numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad.
Transpose: Drag vertically to transpose the pitch of the region in semitones; or tap, then edit the value numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad. See Transpose and fine-tune audio regions.
Fine Tune: Drag vertically to adjust the pitch of the region in cents; or tap, then edit the value numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad. See Transpose and fine-tune audio regions.
Delay: Drag vertically to adjust the region delay; or tap, then edit the value numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad. You can use negative values to have the region play ahead of the beat.
Reverse switch: Tap the switch on to have the region play in reverse. The Reverse parameter is not available if Flex & Follow is turned on in the Region inspector. See Reverse audio regions.
Speed pop-up menu: Choose a multiple by which the original speed of the region changes (audio Apple Loops only). See Change the playback speed of audio regions.
Pitch Source: For audio Apple Loops, this determines whether the region changes pitch based on the key signature. The options are: Off (default) and Key Signature*. See Pitch Source parameter.
*For projects created in an earlier version of Logic Pro, audio regions also have a Project Key option.
Note: Audio Apple Loops have a Pitch Source parameter, audio regions do not.
Follow Tempo switch: Tap to set the region to follow the project tempo. The Follow Tempo switch is available for regions on audio tracks with the Flex switch set to Off (audio Apple Loops only).
Flex & Follow pop-up menu: Choose whether the region follows the project tempo, whether it aligns with only bars or with bars and beats, or choose Off. The Flex & Follow pop-up menu is available for regions on audio tracks with the Flex switch set to On. See Set Flex & Follow options for audio regions.
Original Tempo: Shows the original tempo at which the region was recorded. See Change the original tempo of audio regions.

Quantize audio region parameters

Quantize pop-up menu: Choose the note value to which note events in the region are time corrected, or choose Off for no quantization.
Q-Swing: Set the percentage by which the position of every second point in the current quantization grid is altered. Values over 50% delay beats, and values under 50% pre-delay them. The most practical settings fall between 50% and 75%, imparting a swing feel to strictly quantized or tightly played audio or MIDI regions.
Q-Strength: Set the percentage value to determine how far a note is shifted toward the nearest grid position. 100% results in full quantization; 0% leaves the note at its recorded position.
Q-Range: Defines which notes are quantized based on their proximity to quantization grid positions. At the default value of 0, every note is quantized. At positive values, only notes outside the set range (that is, farther away from the grid position) are quantized, and notes in the range keep their original position. At negative values, only notes in the set range are quantized, and notes outside the range remain unchanged. The amount by which notes shift toward the grid positions depends on the Q-Strength setting.
For example, with Q-Range set to 20 ticks and Q-Strength to 50%, only notes that are more than 20 ticks off are quantized. Those notes are quantized by 50%, which improves the timing without making the performance sound mechanical.

Fade Start audio region parameters

Time values for Fade Start parameters are expressed in milliseconds, with a maximum time value of 99999 ms (100 seconds).

Style pop-up menu: Choose Fade-In or Speed Up.
Time: Adjust the start time of the fade in, either by dragging the value up or down, or by tapping the value, then editing it numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad.
Curve: Adjust the start curve of the fade in, either by dragging the value up or down, or by tapping the value, then editing it numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad.

Fade End audio region parameters

Time values for Fade End parameters are expressed in milliseconds, with a maximum time value of 99999 ms (100 seconds).

Style pop-up menu: Choose Fade-Out or Slow Down.
Time: Adjust the end curve of the fade in, either by dragging the value up or down, or by tapping the value, then editing it numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad.
Type pop-up menu: Choose a fade type for the fade out. The choices are:
- Out: Creates a standard fade-out whenever the Fade tool or Fade parameter is used.
- X (Crossfade): Crossfades the selected region with the following region when you use the Fade tool or Fade parameter.
- EqP (Equal Power Crossfade): Results in an equal power crossfade. This minimizes volume dips between audio regions, resulting in a more even crossfade between regions that may be slightly different in level.
- X S (S-Curved Crossfade): Delivers an S-curved crossfade. The fade curve, as the name suggests, is S shaped.
  The last three items in the pop-up menu can only be applied to the first of two consecutive regions. Also note that the Fade In (and corresponding Curve) parameters are made redundant when any of the X, EqP, or X S options are chosen.
End Curve: Adjust the end curve of the fade in, either by dragging the value up or down, or by tapping the value, then editing it numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad.

Details audio region parameters

Position: Shows the region position in bars, beats, division, and ticks. To change the region position, tap the Position value, tap the unit you want to change, then edit it numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad.
Length: Shows the region length (duration) in bars, beats, division, and ticks. To change the region length, tap the Length value, tap the unit you want to change, then edit it numerically in the numeric input dialog using the Decrement/Increment buttons, the scroll wheel, or the numeric keypad.
Lock Time Position switch: Tap to lock the time position of the region, so that it cannot be moved inadvertently.
