Hi and welcome...

I have the tutorial dvd. I found it quite useful and have watched it several times over, although it doesn't cover EVERY feature of WK's VAST abilities. And yes - it is equally suited to the 3200/3700 as their interface is almost exactly the same (I used to have the 3000 before recently upgrading to the 3200).

Hope this helps, and welcome again to the world of Casio WK - I'm sure you'll have much creative fun with your new board!!

Chris
