Craig, I know that sound is conseptual, still, for MY playing demands, is not good in off...and for the record, I owned not one, but 2 Ketron SD1s for over 5 years....and may I said, I also consulted for most "pros" Ketron users in the Phoenix area, and the only reason I change the SD1, was the lack of polifony.
And to edit voices, you must have good "raw" wave forms, in the T2 case, that is the point, it has them but not at the same quality level of the S.A. Acoustic Guitars, Sax, etc. Yamaha has the know how, but when came to the T2, desided not to use the MO/S90 ES technologies in certain voice families.
I do love my T2, and I would like to see improvements for the next generation of Tyros#.
