As I said m8, which you seemed to have deliberately cut-off to make it seem like that was MY view....I was only passing on an alternate view given to me by someone else.

I personally have not heard it.

I HAVE used an XS pretty extensively even to the point of TRYING to get use it as an arranger.

It did not really come close. I mean, some of the arps are cool for about 16 bars, but try running even four different ones over a 5 min jazz tune, and they soon get tiresome. No half-fills, no variation fills, even the arps within a category are very similar.

And, live, I found the only way that really worked without too much forethought was having the variation start immediately on the button press.
Having to think a bar ahead was a pain.

LOL, I can tell you you really need to have good button pushing timing!!! I had some funny segues at times
