Creating an Audio-to-MIDI Groove Template
You can create MIDI groove templates from digital audio material. This allows you to

the resulting groove template to quantize MIDI regions.
Note: Make sure to disable the Edit > “Snap Edits to Zero Crossings” setting in the Sample
Editor.
To extract a MIDI groove template from a one-bar drum loop

points for your own processing.
