Pages

The "left most" page is always the Sequencer ("Seq") page, where you can edit the steps of the currently selected pattern.

Each track has multiple pages, where different aspects of the track can be modified. These pages are accessed by turning the value knob left or right. Turning the value knob to the right will scroll through the other pages, covering everything from sound design to side chaining and patch presets.

Sequencer

The "left-most" page is always the Sequencer ("Seq") page, where you can edit the steps of the currently selected pattern. This is the most important page where a pattern's steps can be modified in detail. This page shows which steps currently have notes assigned to them via the LED grid, whereas most other pages show which 1-16 buttons have parameters behind them that you can modify.

Note that in pages other than the Sequencer ("Seq") pages, holding down write temporarily reveals which steps currently have notes assigned to them, as if you were on the Sequencer ("Seq") page. Letting go of write will once again show which 1-16 buttons have parameters behind them that you can modify.

Patch (and selecting presets)

The "right-most" page is the Patch ("Pach") page, where you can select preset patches and - through the context menu - perform things like backing up patches, or copying them to other tracks.

Holding any button with lit up LED and then turning the value knob, will load a preset. Note that you can, for example, load a Ki (kick category) patch onto, say your 3/Ld/Lead track if you so wish.
