Like in a concurrent arp device, It would be cool to get an inversion setting (option in midi control for the 3rd knob - vel/notes - ) with the number of the note it should begin.
Eg : C major chord. Setting 1: C E G, setting 2: E G C setting 3: G C E
A 4th setting would be “closest” to the previous chord. hit C > CEG then hit A >C#EA
