This caught my eye because it adds “clip launching”
Probably the biggest visible change in Ardour 7.0 is the arrival of “clip launching” similar to the workflow pioneered by Ableton Live and now also provided by Bitwig, Digital Performer, Logic and others.
Clip launching allows you to experiment with combinations of various loops and one shot samples, with all sound appropriately (but optionally) time-stretched to fit the tempo map of the session, and start/stop quantized to the groove.
