Forum: VirtualDJ Skins - Topic: Calculate the BPM difference

Hello,

I search a solution to calculate the difference between the deck 1 BMP value and the deck 1 BMP value.

It is possible ??

No.

ok,

and it's possible to put de bpm value in a variable ? ex : set '$MYVAR' %Bpm

I'm afraid no, too...

I am really unlucky...

I search a possibility to have an "alarm" if my 2 songs are not Synchronized.

I have found Trick, I placed a button which flashes if the pith is 0 % :

<button action="deck 1 pitch 100% ? blink 400ms : off">
<size width="131" height="40"/>
<pos x="243" y="198"/>
<selected x="438" y="1320"/>
</button>

if you have another idea ?


(sorry for my english)

If all you need to know is if both tracks are synchronized then you can use the following:
<button action="deck 1 get beatdiff 50% ? on : off">
<size width="131" height="40"/>
<pos x="243" y="198"/>
<selected x="438" y="1320"/>
</button>

The above code relies on the CBG info. The button will turn on every time two CBG squares are aligned.

If you want to know if both tracks (LEFT/RIGHT) have the same BPM then you could download "Watchdog" plug-in. However you need to be a Professional Edition User in order to download plug-ins.

Effectively that I want knowl it's if the 2 titles have the same BPM. :(

Hi you need a textzone in your skin with the format
"`get browsed_song 'bpmcompat'`" This reads the diff between the playing track and the browsed track.
"`deck 1 get loaded_song 'bpmcompat'`" This reads the diff between the track on deck 2 and 1 (maybe "deck 1" isn't necessary)

Thank you very much ! I did not know this command !

But it don't work if I test this :
<textzone>
<size width="86" height="31"/>
<pos x="855" y="990"/>
<text font="Tahoma" size="15" color="#006767" align="right" format="`get loaded_song 'bpmcompat'`"/>
</textzone>

or this
<textzone>
<size width="86" height="31"/>
<pos x="855" y="990"/>
<text font="Tahoma" size="15" color="#006767" align="right" format="`deck 1 get loaded_song 'bpmcompat'`"/>
</textzone>

the result is strang : I put the same song on the deck 1 et deck 2. If the 2 pitch are on 0, the résult is 0. But if I put the two pitch on another value, for example +3% on the 2 desk, I have a résult <> 0 !?!

(again sorry for my english)

hm....

You use a skin that's version 7 ?.cause it workted fine here.

I use one of the skin that I made I even (http://fr.virtualdj.com/addons/12335/2_SCREENS_Millenium_Skin.html )

I studied the bpmcompat command. If I use the Textzone, this fonction calculate the différence between the current BPM and the original BPM of the loaded song :

1 is this Textzone :
<textzone>
<size width="54" height="31"/>
<pos x="312" y="989"/>
<text font="Tahoma" size="15" color="#006767" align="right" format="`get loaded_song 'bpmcompat'`"/>
</textzone>

2 is this :
<textzone>
<size width="36" height="31"/>
<pos x="380" y="989"/>
<text font="Tahoma" size="15" color="#006767" align="right" format="`deck 1 get loaded_song 'bpmcompat'`"/>
</textzone>

and 3 is this :
<textzone>
<size width="29" height="31"/>
<pos x="912" y="990"/>
<text font="Tahoma" size="15" color="#006767" align="right" format="`deck 2 get loaded_song 'bpmcompat'`"/>
</textzone>


You can see that the 2 songs are synchronized, but the bpmcompat calculate a difference of 3.1 ! This is also the difference between the original and the current bpm..

However in the Browser, the calcul is correct (between the songs in the browser and the masterdeck)

As I told you, there is a plug-in you can use for that. You can even use it on skins or controllers!
http://www.virtualdj.com/addons/12817/WatchDog.html
This plug-in will set a variable to "TRUE" when the bpm difference of the loaded songs is less than 0.03 BPM
You can query this variable to do whatever you want to do:
var_equal "$WD_BPM_LR_SYNC" 1 ? hands_up : hands_down

However you have to be a PRO user in order to download it.

PS: I'm not advertising my plug-in. I wanted the same thing as you and since there was NO WAY to get via native VDJ Script commands I created a plug-in for it...

I thought that with my license I could not download your plug, but I made a mistake !

Ok, I have download the WatchDog, install it and activate it in VDJ.

Then I created a button :

<button action="var_equal '$WD_BPM_LR_SYNC' 1 ? on : off">
<size width="20" height="18"/>
<pos x="480" y="433"/>
<over x="+0" y="+1028"/>
<selected x="440" y="1680"/>
</button>

but it don't work...

Sorry, my mistake. The variable you should query is "$WD_BPMLR_SYNC"

It work very well !!!

Thank you very much !!!
