The arp in Current is fantastic, but I think a way that it could be improved is by utilizing some of the features found in the Ana 2 Arp, which is one of the best Arp’s I’ve come across:
Specifically, the Pattern Area with a visual of Notes 1-6 to dictate, for example, when a 3-note chord is getting played back, you’d have blocks in the pattern area on Notes 1, 2, and 3 with the ability to add notes either an octave up or down for a top line.
This would be awesome to see implemented (eventually) in Current.
