This is interesting stuff.!!! I meant to add that I had both keyboards in "split" mode.I have given up trying to play jazz chords in "split" mode- I save that for the organ. since I am not a pianist, and I can play the root in the base, and as you say Alec, there is so much going on there isn't much point in it. Sometimes a 9th works O.K. However I have found that if I dont get the right chord registering on the screen the base will not play the correct notes.For example, If I play the Ab major 7 9 as above and it registers as C min 7 I get the bass playing a C instead of an Ab. My teacher is very pedantic about this and listens to the baseline very carefully, If I put the "on bass" on it means I have to play every chord with the required note at the bottom and that may not be in the most familiar inversion -Just for the sake of a couple of chords. I have at times muted the bassline and sequenced in my own which means I can vary the bass to my own liking. What do you think of this? No good for playing "live" I know but I am mostly concerned with sequencing for "backings" for my choir.
Although I have compared the Roland and the 6500 in this feature the 6500 is far more versatile in what you can do with it. I am utterly astounded at its performance. No one keyboard can have everything- I think you just have to work out what is important to you personally. Reguards. Jean.
