Hi Tammy,
I purchased a CTK 811ex last September from my piano music teacher(Kevin). He liked it so much that he updated to one as well.
It is my first keyhoard and so it is a steep learning curve at the moment.
I have downloaded files off the internet and play them through Musictime software. If you want some ill send them to you.
My keyboard did not come with the video so I am relying on the terribly written instructions that came with the keyboard. Any tips will help.
I am mainly interested in cool jazz and standards.
Kevin is a professional teacher and musician who has played with a lot of the greats downunder(Australia).
We jam in his shop with either him on the casio and me on the piano or vias verso.
If you have anything in particular you would like to discuss let me know. I am still a beginner of electronic music but I will try my best.

Regards
RayD.
