Ok - I’m a dummy. Arp swing is achievable similarly to the MNM.
From Tarekiths MNM tricks & tips :
Faking arp Swing:
I’ve managed to make a “swing effect” with the arp alone.*
If you set the arp to key mode, fastest speed. (1x) And only a trig on step one, and 9, it will have something like 65% swing. If you set the second trig on step 8, it will have something like 58%. On step 6, it has no swing. (50%) This way you can also have a lower swing than 50%.*
What feature to complain about now?
How about midi-loopback without needing a cable?
Some other way of getting more tracks.
My use-case is making radio-ready music on the DN alone.
