Synth patches have a set of parameters auto-mapped to midi controller for performance (like ableton)
Just like ableton live instrument racks.
This way, you only have to set in the deluge global setting a set of midi CC# your performance controller sends (a set of 8 CC is usually good for expressive performance).
Each synth patches have its own set of 8 carefully chosen parameters that'll give that unique patch it's own expression "palette". Those parameters will be automatically controlled by the 8 CC# global set whenever this track is selected.
Expression and automation made easier : "auto-mapped".
That would make each synth patches expressively shines without headache.
Drum tracks (drum sets perhaps) could have the same.
Ableton nailed it and I think it could be easily done on deluge.
