2 Do one of the following, depending on the options available in the editor:
• Choose Functions > Undo Quantization, or use the corresponding key command (Score
Editor, Piano Roll Editor, and Event List).
• Choose the “off” setting in the Quantize pop-up menu, then click the Quantize button
(Piano Roll Editor and Event List).
• Option-click the Quantize button (Piano Roll Editor and Event List).
• Option-click one of the selected notes with the Quantize tool (Score and Piano Roll
Editors).
Important: Use of region-based quantization after you have individually quantized note
events within a MIDI region will override your event-based quantizations, so take care. It
may be worthwhile writing such changes into the region by following the instructions
outlined in Quantizing MIDI Regions Permanently. Then all your hard work creating a
number of individual event quantizations will not be lost by quantizing the wrong region.
Working with Groove Templates
You can create quantization grids based on the rhythms of other audio or MIDI regions.
These are referred to as groove templates. Groove templates make it possible to capture
the small timing deviations that give an audio or MIDI region its feel, and apply them to
other audio or MIDI regions.
You can even take the feel from an audio region and apply it to a MIDI region—helping
a MIDI clavinet part to sit well with a funk guitar Apple Loop, for example (see Creating
an Audio-to-MIDI Groove Template).
To create your own groove template
1 Select the audio or MIDI region you want to create a groove template from. (You can also
select multiple regions to create a groove template, and all of them will contribute their
transients or notes to the new groove template. When there are multiple transients or
MIDI notes around the same musical position, however, only the first will be evaluated
for the groove template.)
