Also, don't neglect the smaller sequencers. A few companies (Xaoc and Ladik come to mind) offer 4-step sequencers...and at first, that might seem really underfeatured. But if you use something like a clock counter (this sort of thing: https://www.modulargrid.net/e/emw-pulse-counter) to step it, you can then sequence your harmonic patterns by using the 4-banger to shift the other sequencer(s) global pitch CV. So, those are just PERFECT for stepping through typical chord changes, especially where you only have 3-4 chords in the track.
