im doing my own instrument and i want to use the arpeggiator but only in one group, i want the others to play normally but i dont know where and how modify the script to do that
Hmm...
Maybe you should make a couple of Kontakt tracks, then make a same melody for each of them.
Then use in-DAW arpeggiator for only one or 2 tracks, while the rest can play normally.
This is the best I can help you with.
