Bernie,
The more I learn about my SD7 the more pleased I am that I bought it. I did try the PA4X but for the sake of me I just could not get the same quality of sound from it that my SD7 provided. I probably am not a buyer of the SD9 but you never know. I really like the onboard speakers of the SD7.

I elected to use styles rather than registrations because the SD7 is limited in how much you can organize the registrations in the four banks. With styles on either on the hard drive or a thumb drive the potential for developing gig lists is unlimited. So I can have 1940's, 1950's, 1960's songstyles all ready to go plus any other of many categories for gigs. Very exciting.
