Split Current Track by Note Number
This command splits all of the different notes used on the current track to new tracks, one for each note used. This is especially useful when more detailed editing of a drum part is needed and you want to be able to edit the different drum notes independently (i.e. kick drum, snare, hi hat etc...).
The current track is split into individual new tracks and then muted so that you only hear the new tracks. Once your edits are complete you can combine the tracks back into a single track by selecting Tracks - Combine Selected Tracks.
