Suprised Fran did not butt in here, as I recall that my Roland E70 as well as the Roland G800 and I presume also the famed G70 had a truly Dynamic Accompaniment in that you could set values of +64
to -64 for each and every acc. track thus allowing you to be very expressive. I have always wondered why a reknowned makes such as Korg and Yamaha did away with that. I sorely missed it after moving from Roland to Korg, I guess now I have got used to it.
But is was a superb feature on these boards.
