Tip: To obtain the best Q-Range results, use a low, even quantize value, such as 1/4
note. Set the Q-Range parameter to compensate for the maximum error in the recording.
• Q-Flam: Spreads out notes with the same time position—chords. 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 that all notes
start at the same position—in the arpeggio is unaltered.
• Q-Velocity: 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: 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, whereas 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.
Quantizing Audio or MIDI Regions
You can quantize audio or MIDI regions, or a mixed selection of audio and MIDI regions.
Note: In order to use quantization on an audio region, you need to assign a flex mode
to the parent audio track, and select the Flex parameter in the Region Parameter box for
that region. For details, see
Choosing Flex Modes .
To change the quantization grid division for selected audio and/or MIDI regions
µ
Choose a value from the Quantize pop-up menu in the Inspector’s Region Parameter box.
You can also step through the available Quantize values, one at a time, with the “Set
Quantize Parameter to Next Value” and “Set Quantize Parameter to Previous Value” key
commands.
You can do this at any time, including when Logic Pro is in Playback or Record mode. The
new value is immediately used to alter note playback positions.
