Choose a quantize algorithm for MIDI regions in the Tracks area in Logic Pro for iPad
The Q-Algorithm parameter in the Region inspector lets you choose from two quantization types for MIDI regions: Classic Quantize and Smart Quantize. Whatever type you choose is also displayed for the Algorithm parameter in the Note inspector and used when quantizing notes in the Piano Roll Editor.
Classic Quantize quantizes MIDI notes to the nearest grid using the current Quantize settings and any advanced Quantize parameters.
Smart Quantize works similarly to quantize 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 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.
Choose the MIDI quantization type
In the Tracks area menu bar, tap the Trim button
.Tap a MIDI region to select it, or select multiple MIDI regions.
Tap the Inspector button
on the left side of the view control bar (or press I on your external keyboard) to open the Region inspector.Tap the Quantize disclosure arrow to show the Quantize parameters.
Tap the Q-Algorithm pop-up menu and choose Classic Quantize or Smart Quantize.
