I would have to give this one to Ketron.
The implementation of audio loops for more than one track in a style IMO is a major step forward from the SD1 product.
Also, the ability to have audio guitar and other chord instruments follow your cords in real time is very forward looking from the SD product.
Yamaha with their T1 to the T2 gets the second prize for the implementation of SA voices.
Although it is something good, SA is just a sophisticated way of velocity switching and legato programming. It is an extension of sound manipulation that has been around for decades.

Roland and Korg have not done anything revolutionary from one TOTL arranger to the other with in the past 8 years.
