set_skin_offset(). So if we create a wallpaper sprite which is as double as high as our ui_size (in this case 2 x 608px) we can put 2 wallpapers into this one image file like shown on the left. The visible area is only from 0 pixel to 608 pixel.
We can now set a button for example which moves the background skin 608 pixel vertically to put the second wallpaper into the visible area. This short demo video shows how it works:

on init
make_perfview
set_ui_height_px(540)
set_control_par_str($INST_WALLPAPER_ID,$CONTROL_PAR_PICTURE,"wallpaper")
declare $count
declare ui_button $switch_wp
set_control_par_str(get_ui_id($switch_wp),$CONTROL_PAR_PICTURE,"btn_1")
set_control_par_str(get_ui_id($switch_wp),$CONTROL_PAR_TEXT,"")
set_control_par(get_ui_id($switch_wp),$CONTROL_PAR_WIDTH,40)
set_control_par(get_ui_id($switch_wp),$CONTROL_PAR_HEIGHT,40)
set_control_par(get_ui_id($switch_wp),$CONTROL_PAR_POS_X,296)
set_control_par(get_ui_id($switch_wp),$CONTROL_PAR_POS_Y,430)
end on
on ui_control($switch_wp)
if ($switch_wp=1)
$count := 0
{set_skin_offset(608)}
while ($count<609)
set_skin_offset($count)
wait(1000) {set to zero to switch instantly or remove this whole while loop}
inc($count)
end while
else
set_skin_offset(0)
end if
end on
For the video demonstration we did a slow animation but of course usually you wanna switch the wallpaper instantly. With wait(0) there will be no animation.
Or you can remove the whole while loop (but don’t forget to add the set_skin_offset(608) again then)
Set Skin Offset vs Label element layer
You can also set a background wallpaper via label element. It’s up to you which method you prefer the most. Both have advantages and disadvantages.
With the label element it is much easier to design a background image. We can work with layer groups in our graphics tool. This way we can for example reposition elements for all our Kontakt menu screens at once. With set skin offset however we have to create a long image “tube”. which no longer allows us to rearrange elements at once.
The set_skin_offset method however is somewhat easier to handle when it comes to coding. It’s also less error prone. Also we can wallpaper the first 68px (where the Kontakt panel resides) which is not possible with the label element layer.
Set Skin offset (this)
Remove the row
Column: 1
Cons
- cumbersome graphic design
especially when working with many similar wallpaper-screens and graphic layers
Column: 2
Pros
- covers the whole area
including the first 68px which cant be addressed by KSP - slightly easier coding
Label Element (learn more)
Remove the row
Column: 1
Cons
- doesn’t cover the first 68px
- slightly more complicated coding
Column: 2
Pros
- better graphic design workflow: less frustration and mistakes
especially when working with many similar wallpaper-screens and graphic layers - redundant graphic design work can be better achieved
since in your graphics tool all wallpaper screens are layered on top of each other we can for example test different backgrounds for all screens at once

if I want to make displaying notes on the virtual fretboard the notes pressed on the MIDI keyboard .how it works?YummyBeats
uh sorry that's a little too complex for the comments here. Extemporaneously, I would work with an array matrix (holding the x & y positions for each note)
