I have to agree with Squeak about the pricing. I have always wondered why Ketron pricing was so high, but it never stopped me from buying one. I can't sell ketron short though, there sounds are great, if not top notch. I love my s900 but I miss those ketron drums, bass and sounds.

The pattern expan. helps a lot but if you have a HD you can also load styles from the HD to the user banks. The harmonizer is optional but after trying to tweak & tweak my harmonizer on the s900 to no aval, I'll gladly pay for a ketron harmonizer.

I know that everyone tastes are different, but when you have a ketron sd5 pumping through a sound system, it sounds amazing.
I'm thinking of a SD3 with my S900 in the future.
