Rhythm Ferret, Ardour’s counterpart to ProTools “Beat Detective”, already supported transient and note onset detection in Ardour 2.X, and allowed you to split regions based on those detected features. But in Ardour 3.0, you can now do much more powerful drum and related editing because:
- detected feature "marks" can be manually moved or removed
- you can now snap the region segments to the grid
- Region menu contains "Add transient" to manually add transients at the edit point (best to use playhead as edit point)
There are additional tweaks to close gaps between regions after snapping region segments to the grid. The split and snap operations will also pay attention to track grouping.
