I have no idea of your level of keyboarding but i’ve found that polyphonic aftertouch gives benefits to people with even less keyboard skill. You don’t necessarily have to have great speed and movement on the keyboard to benefit.
For instance the use of ratcheting in arpeggio patterns controlled by poly aftertouch as demonstrated in the Loopop Keystage video would be easy to do if you can finger the chords and hold them. Other arp things for instance could potentially be set to P-AT control.
Same with filter modes per note, or other changes to the sound of the notes is easy to use dramatically.
