It'd be great if you could put several arpeggiators in a row.
say, start with a chord trigger for a chord strum (1/8) with one Repeats and then an UpDown (1/16) for 4 Repeats and you would automatically get that "drang dra-gri-dra-gri drang dra-gri-dra-gri" campfire-hippie-guy-who-brought-a-guitar kind of strum
And then ofcourse you could make pretty intricate classical progressions of arpeggiation with say ie. 4 successive Arpeggiators with different Styles (and perhaps even Rates) to automatically (but of course with full control and intentional) make working and perhaps even good enough drafts of proper arpeggio arrangements.
Of course then the request I've made for baking arpeggios would be great to take it to finalising the arrangement!
