I'm reading the factory mapping of your controller and I can already see how the pad pages are mapped.
I'll try to explain why you had this behavior when changing pages to other than the factory ones on the controller.
Just imagine folders and files in Windows. Folders are named with the numbers 1, 2, 3, 4... files are named with the letters A, B, C, D...
The pad pages are also divided into "pad page 1", "pad page 2"... and "pad page sampler" and "pad page loop." When loading pad page 1, the pad page "something" must also be loaded.
You can change which page will load for pad page 1.
You can set all the numbers from pad page 1 to pad page 4 to the same pad page.
The factory mapping says
1. Cue
2. Loop
3. Sampler
4. Effect
Therefore, you can try changing the mapping by entering the names of your desired pages instead of a number. Then, the pages with the specified names should load.
The modified script should look something like this:
<map value="CUES_MODE" action="pad_page 'pml cues'" />
<map value="LOOP_MODE" action="pad_page 'pml loop'" />
<map value="SAMPLER_MODE" action="pad_page 'pml sampler'" />
<map value="EFFECT_MODE" action="pad_page 'pml effects'" />
You can find the exact names of the pad pages in the settings.xml file somewhere in the line with the most recently loaded pad pages.
I assume PML stands for party mix l? But you can use the regular Cue, Loop, Sampler, Effect pages.
One last thing, you can go to mallmuzik/tools/external controllers/edit mapping and import the file for your controller there, then check the F1 help.
Also, check if you haven't added:
'P' to change the default pad page switches to quick pad page selection mode, or return to the default pad page switches.
If you've added quick pad page selection, try removing this switch.
Press "p" in the mapping editor and confirm the switch removal.
Keep a copy of the factory mapping, and if you have any problems, don't reinstall VDJ. Simply overwrite the controller mapping file in the VirtualDJ/mappers or custom mappers folder, or preferably in both locations. ;)
Below is the factory mapping file; I hope it helps.
