MIDI and Audio Regions Compared
The following overview sums up the main differences between Audio and MIDI
Regions. There are some notes at the bottom of the table to clarify the most important
points.
Naturally, some of the parameters that can be applied to MIDI events have no effect on
audio signals. Equivalent operations for most of these are available as destructive edit
operations in the Sample Edit window.
