Hi John,
Did you check out the website. Hours of video clips on the site ,under Registrations .

I’m having problems putting up the link, fingers crossed.

Most of the stuff I wouldn’t use, but when I see registrations for, james last, Bert Kaempfert Glen Miller, symphony orchestra, plus a few more, definitely might be tempted to buy some
even if they seem pricey.

The girl who does some of the demos , is great, explanation on how to use them etc

Have to put in the keyboard you want them , as it appears not all the same stuff is available for all the models . Could be wrong. I put in the sx900
