in the interim ive found a bit of a solution but frankly its a tad 'fiddly'.

1..i auditioned single note rt's (only a few) in the rt picker search then genned.
2..then via audio editing and pitch shifting i managed
to create a custom arp. that fits the song.

i'm gonna experiment further with more rt's seeing if i can isolate single notes. it aint easy lol.

best to all.
