Each entry in the registry bank contains the settings stored in all 8 registration buttons. Under each register button all kinds of settings (voice, style, tempo, dsp settings, function buttons, pedal mode and many more) are stored. So to make it useful for a particular song you want to play, you can store not alone various different instruments, but also effects, switching to a next variation, volume and samples under the 4 pads buttons. I think you should start with register button 1 and work you way up to even 8 per song you want to play. You can even assign a foot paddle to switch up from one register button to the next. Then you can keep you fingers on the keyboard. Leon Castonguay has a nice tutorial about PSR SX900 registration memory actions.
You can add two of at least 64gb memory sticks in the back of it. And as many as there are extra styles and or voices. To date There are over 250,000 styles added to mine above standard. All are accessible. Remember to place folders on the root not embedded. Although, many have three folder deep too and they all work. There is no limit.
Hey sir,I think it actually memorizes ALL 8 of those buttons under that specific name you select - not just one of the buttons. You can basically prepare a set of sounds, rhythms and other stuff for one song or even your most favorite ones and then just quickly load them. If you press only the left/right button, it will toggle the memory banks. I suggest you read into user manual - these are great machines. I have one too, but don’t have as much time to use it as I would wish.
