Logic Pro for iPad MIDI region parameters

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

General MIDI 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 in Logic Pro for iPad.
Velocity Offset: Drag vertically to set a velocity value by which MIDI notes in the region are offset from their original values; 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.
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.
Pitch Source: Determines whether the region changes pitch based on the key signature, and (for Session Player regions) on the Chord track or on region chords. See Pitch Source parameter. The options and defaults for each region type are:
- MIDI: Off (default), Key Signature*
  *For projects created in an earlier version of Logic Pro, MIDI regions also have a Project Key option.
- Pattern: Off (default), Chord Track, Region Chords
- Session Player: Chord Track, Region Chords
Dynamics pop-up menu: Choose a value to expand or compress the dynamics (the difference between loud and soft) by adjusting the velocity range. This works in a similar way to a compressor or expander. Values above 100% increase the difference between high and low note velocities, while values below 100% decrease the difference.
The Fixed setting forces all notes to a velocity value of 64. This can be used together with the Velocity Offset parameter (see above) to set any fixed velocity value.
Gate Time pop-up menu: Choose a value to modify the duration (length) of notes in the region, making them either more legato or more staccato. Values below 100% shorten notes, and values above 100% lengthen notes. The Fixed setting produces extreme staccato, and the Legato setting produces strong legato regardless of the notes’ original length, eliminating all space between notes.
Clip Length switch: Tap to alter the length of the last notes in a region directly from the Tracks area by adjusting the length of the MIDI region. When switched on, any notes sounding at the region end are abruptly cut off. When switched off, notes are played to their normal end point, regardless of whether the region end is reached sooner.

Quantize MIDI 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.
Q-Flam: Notes with the same time position (chords) are spread out by this parameter. Positive values produce an ascending (upward) arpeggio; negative values a descending (downward) arpeggio. The position of the first note (either the bottom or top note, assuming all notes start at the same position) in the arpeggio is unaltered.
Q-Velocity: When used with a groove template, this parameter (expressed as a percentage) determines the amount that the velocity values of quantized notes are affected by the velocity values of a template MIDI region. At a value of 0%, the notes retain their original velocity. At 100%, they adopt the velocity values of the template. Negative values alter the velocity, making the deviation from the template even greater.
Q-Length: When used with a groove template, this parameter (also expressed as a percentage value) determines how the lengths of quantized notes are affected by the equivalent note lengths (notes at the same position) of a template MIDI region. A value of 0% has no effect, while at 100%, the notes adopt the exact note lengths of the template region. Negative values alter note lengths further, resulting in a more significant deviation from the template.
Q-Algorithm pop-up menu: Choose a quantization algorithm to use for the region. The choices are:
- Classic Quantize quantizes MIDI notes to the nearest beat using the current Quantize setting and any advanced Quantize parameters.
- Smart Quantize works similarly to Flex Time for audio regions. MIDI events near grid positions (defined by the Q-Range setting) are analyzed. Based on a combined weighting of proximity to the target grid position and velocity, a reference point (“center of gravity”) is set for each group, and moved to the target grid positions. All (nearby) MIDI events move proportionally to the reference point. How far each event moves is determined by the Q-Strength setting. Unlike Classic Quantize, all MIDI events keep their original order, similar to an audio region edited using Flex Time. This includes not only notes but also all MIDI data types (such as Pitch Bend and Control Change events).
  In many cases, Smart Quantize can produce more natural-sounding results than Classic quantization. For example, in a MIDI piano performance, the notes of quickly arpeggiated chords keep their relative positions, as do sustain pedal (on/off) events. Another useful situation is in MIDI drum performances that need some quantizing, but where Classic quantization would distort rolls, flams, and other notes not played strictly on the beat (and also possibly the relative position of Hi-Hat on/off events). In both cases, Smart Quantize keeps the relative position of note on, note off, and CC events.

Details MIDI region parameters

Position: Shows the region position in bars, beats, division, and ticks. To change the region position, drag a Position unit vertically or tap the Position value, then edit the value 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, drag a Length unit vertically or Tap the Length value, then edit the value 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.
