Usually I will being I have saved all setups in folders on my PC for each brand keyboard and just load them into the new ones
edit and tweak a bit and I am on my way BUT,..with this new SX900 I want to start completely from scratch using all available within the unit first to setup the play list, audition all styles and see what I can obtain for my songs using internal styles and sounds multipads, etc,and only then dig into my own custom user styles to add into the Sx900. In the past I would get a new keyboard, load it up with my setups and next day be on stage playing it....but now I have much time to really dig deep and make the SX900 sound and feel the way I would like.
