Diki,
Both of my current arrangers ( PA80 and MZ2000 ) have this feature. I never really gave much thought to it being useful to a live performer, at least not for live arranger play, but now I can also see where you're coming from with this and why it might be useful to a live performer as well.
Instead, I thought of the songwriter who wants to "scratch pad" new ideas or songs, or perhaps who wants to build a quick tune to turn into a sequence ( that might later be used in a live performance ). Now though, we see the live player who can also use this feature. Personally, I like apps like Band in A Box and Jammer that allow me to step enter chords with patterns when playing around with new ideas.
Unfortunately, on this one Roland owners are out in the cold. Why don't I include Yamaha ? Because One Man Band and XG works exist, ( although I think at this point XG works is now just a distant memory ). Both of these apps have the capability of step entering chords. You can simply transfer the finished product to your arranger.
There was a time when I lamented a bit that this forum seemed to gravitate mainly toward the live player. Two things have changed for me since then. One- I've become more of a live player myself. Two- I came to realize that for me at least, workstations ( hardware or soft ) and software apps like FL, Orion, and the like are perhaps preferable choices for writing or making new music.
