Looking to purchase a new full size keyboard. Have mainly used Kurzweil and Yamaha. One important feature I would like to have is that the keyboard maintains the sound while switching sounds while you are playing. My current Yamaha does not and I think that's important. Of course, I'm also looking for quality piano and piano and string sounds. It will be used with a band consisting of the keyboard, bass, electric and acoustic guitars and drums. Price ranging up to around $4K.
