The Ensoniq SD-1 I saw seemed to be quite "out-dated", being made in '92. I believe I could get something newer and be more ahead technollogy wise. Is there a newer model?

The Roland looks great, but I would be using it for rock style music, and some of the reviews said it wasn't great for rock. As for the Korg's and Yamaha's, they look great, but quite pricey. Although I have looked at some Korg's that were only slightly out of my range, so I could look for used ones, and they looked very good.

I still would like to know...

1) What is a Vocoder
2) What is an Expansion Board
3) Is a Moog a brand or a type of Keyboard
4) What is a "Sample Board"

This is a little off topic, but also does anyone have any good websites for free sheetmusic.
