Marketing jargon...plain and simple....all companies use it...consider some of the patch names on your G-70.

The area that the Tyros1 lacked was authentic Hammond organ sounds...they were good, and some were very close, but they didn't fool anyone.

Roland has always done a better job, and I was actually looking at a VK-8, an XK-1, or a Nord C1 for those kind of sounds, but I didn't use them often enough to warrant buying another instrument...and these guys weren't cheap.

The Tyros2/3 came to the rescue, and with the improved Hammond style voices, there was no need for another keyboard...but, I like the MOTL S-series better for gigging...I can have two (one for backup) for the price of one Tyros2 or 3...so, if these new SA organ voices are the "real deal" (I hesitate to use that phrase around here ), I will end up with two PSR-S910 for the new year.
