I was just looking for a few extra voices and may I say they work amazingly well in the S670
I am not talking SA voices,....just some missing ones I have always used thru the years on my previous Yamaha models....
I now have triple the sounds to choose from vs the factory ones.
in conclusion...the S670 gotta be the best bang for the buck of any arranger kb on the market. There I said it!!

Thanx all...

that said, I can't wait to buy a Genos in 2029
should be able to scoop one up on ebay for under $1000.00 by then..
