Forum: VirtualDJ Technical Support

Which LEDs ? Of the PADs ? Or the PAD_PAGE buttons ?
And how did you "customized" them, if not through VirtualDJ ? (It's not clear to me because you say that they reset when VirtualDJ starts, which implies you had them configured somehow prior running VirtualDJ)

Still, it's not very clear to me what you have done.

Anyway, the colors of pad pages are controlled by this part of the XP2 mapper:

<map value="LED_PADMODE_1" action="pad_pages 1 ? color 'white' : off" />
<map value="LED_PADMODE_2" action="pad_pages 2 ? color 'cyan' : off" />
<map value="LED_PADMODE_3" action="pad_pages 3 ? color '#ff4000' : off" />
<map value="LED_PADMODE_4" action="pad_pages 4 ? color 'orange' : off" />
<map value="LED_PADMODE_5" action="pad_pages 5 ? color 'yellow' : off" />
<map value="LED_PADMODE_6" action="pad_pages 6 ? color 'yellow' : off" />
<map value="LED_PADMODE_7" action="pad_pages 7 ? color 'yellow' : off " />
<map value="LED_PADMODE_8" action="pad_pages 8 ? color 'yellow' : off" />

Keep in mind that modes 5,6,7,8 are SHIFT+1,2,3,4
You need to edit the colors you want there.

pad_pages is an alias, and it was meant to be used with numbers (pad_pages 1)
pad_page is the correct script to use in most cases. It accepts both numbers and text

Is it possible to paste here the related parts of your mapper ? (a direct copy/paste) ?

It's more complicated than that.
The unit offers 2 modes. Serato and Rekordbox (besides the mediocre Generic MIDI)
At first we opted for Serato mode since it was easier to handle some leds and stuff, including pad page buttons colors.
However due to some performance issues, at a later point we decided to switch to Rekordbox mode instead.
In Rekordbox mode when the device initializes, it uses the default Rekordbox violet colors for the pad page buttons.
To counteract that, we manually send the correct colors (based on the default mapping) once upon device initialization. This is done on definition level. That's why the device shows the colors of the default pages correctly.
If we remove that code from the definition, then the buttons will start violet, and stay violet until you use a pad page button.

I may have a "dirty" solution to your problem, that I also may be able to fine tune at some point later.
For the moment please try to append this code at the end of your ONINIT key:
& deck all pad_page 'rmx-500' & wait 50ms & deck all pad_page 'rmx-1000 drums + rmx-500 drums' & wait 50ms & deck all pad_page 'turnado' & wait 50ms & deck all pad_page 'effector' & wait 50ms & deck all pad_page 'pad fx 2' & wait 50ms & deck all pad_page 'pad fx 3' & wait 50ms & deck all pad_page 'stems + hotcues' & wait 50ms & deck all pad_page 'rmx-1000'
It should "fix" your issue.

Why ?
Does it matter ?
I mean, the buttons have RGB leds. We could literally use "any" color for any button.

Remember, our goal is NOT to provide an exact copy of other software behavior, but to utilize the controller the best way possible to get the most out of VirtualDJ.

So, why should the colors of the PAD MODE buttons should be an exact match of Rekordbox or Serato colors ?
Does it affect functionality or improves anything ?

PS: Even Rekordbox and Serato use two different color schemes. So, why should VirtualDJ use one of the two, and not use a third distinct scheme ?

As I said, it's because of the device firmware.
After some more testing I remembered why it's set that way.
The unit initializes in RB mode with "violet" leds on "main" layer and yellow leds on "shifted" layer.
As you found out (and I was able to confirm) if you don't use the shift button to switch layer (since it's a hardware layer) you can't actually change the led colors for modes 5 to 8 and even our definition "hack" trick doesn't work.
So, the best we can do is to provide a uniform "yellow" second (shifted) layer and a multi color first layer.

I agree that it would be best to have different colors for all the pad modes. But, despite the unit having RGB leds, Rekordbox does not seem to care enough for this*. So, they baked some stuff to the firmware (in RB mode) that makes working with pad page button leds a little more tricky.
*-> Rekordbox uses 4 violet and 4 yellow page modes.

PS: Generally we prefer that devices just provide buttons, sliders, leds e.t.c. for the software to use as it likes.
However, Serato at first and Rekordbox later decided that for some "functions" it would be better to be handled via devices firmware. There are plenty examples of such controllers where the firmware does some "weird" stuff:
A few days ago I replied on another user on this forum for a limitation of DDJ-800 (and I think DDJ-1000 as well). The "Seek <<" (back) button doesn't work when you are near the start of a track! That's not a VirtualDJ limitation or bug. That's baked in the device firmware. Instead of Rekordbox checking if it can go backwards or not, the device does it instead based on the time elapsed and BPM info of the track. And then it decides whether or not to send the button press (MIDI message) to the software!
Such firmware "functions" cannot be bypassed by us. Also such "functions" will some times play an important role to decide if we are going to use "Rekordbox" or "Serato" mode for devices that support both (such as XP2)
Just stay assured that we really try our best to provide the best user experience possible, even when some devices have questionable functionality built in.
