You can also edit the note events of the drum loop slices—enter Main Mode to do this. A new Track with
the note events playing their corresponding slices has been automatically created. Click the T Correct
drop-down menu to use Time Correct to quantize the note events so they fall on exact, even time
intervals. You can also rearrange the note events, thus creating a new playback order for the slices. You
can also edit each slice or sample in Program Edit Mode. You can add effects for slices or use the filter
function to change the frequency range of a selected slice. There are almost no limits to what you can
do.
See Sample Edit Mode > Chop Mode to learn more about this feature.
