The way preset buttons work, switching to another page doesn't get you new presets, it will still display the first N presets in your current song. (where N is the number of preset buttons you have.)
There probably should be some option for bank buttons to move through all of the presets in a song, instead of always moving to the next song.
That's not available yet, so you have a few other options:
- Add hold functions to your preset buttons. If you have preset buttons 1-6, adding hold functions to the preset buttons will make those buttons recall presets 7-12 when held.
- Use a Preset + and Preset - buttons to advance through the preset list one at a time.
