That would be fantastic. I really would vote for that feature.

I have tried out the suggestion with the delay over 32 bars. It certainly produces an interesting effect with which you can work musically. For the phazing technique aka Reich, however, the resolution is too low for my liking. I understand that the to adjust the length of the bar independently per arp is not exactly at the top of the priority list. The phazing technique is a special application. The tip with the delay is an interesting option.

It's great to hear that these features are already on the roadmap. I understand that new features take time to be thought through and implemented. There is no other way. The features outlined would suit perfectly. In chord chain mode, I could also imagine the possibility to edit the length of each chord like 4 beats/bar, 3 beats/bar, etc. Second, offer the available chords to a scale, for example: Select F Dorian as scale, then chords I-VII below will be offered: Fmin, Gmin, Abmaj, Bbmaj, Cmin, Ddim, Ebmaj.
