Help for mapping VuMeter on DDJ-1000

Postby Capitaine_Fracasse » Mon Apr 06, 2020 4:32 pm

Hello guys and girls !

I am working on a mapping for the DDJ-1000, but I am unable to map Vu Meter with the output “VuMeter”.

In traktor the Vu Meter work perfectly by doing this : https://i.imgur.com/5JmL1SU.png .
So, I try this in Mixxx :
Code: Select all
<output>
                <group>[Channel1]</group>
                <key>VuMeter</key>
           <description>VuMeter CH1</description>
                <status>0xB0</status>
                <midino>0x02</midino>
           <on>0x7F</on>
           <off>0x0</off>
                <minimum>0</minimum>
           <minimum>1</minimum>
</output>

In compliance with the manufacturer information: https://i.imgur.com/frEbGej.png

But the only thing I get is a “Peak” (red led) for a specific volume level like the maximum value is sent to the DDJ each time a specific volume level is reach. I tryied different value for on, off, minimum and maximum, but the only change is that the “Peak” is shown at different volume level, still like he max value is sent to the DDJ.
I tryied the advice shown in the Mixxx Forum for the MC6000MK2 :

Code: Select all
 <output>
                <group>[Channel1]</group>
                <key>VuMeter</key>
                <status>0xB0</status>
                <midino>0x53</midino>
                <on>0x01</on>
                <minimum>0.2</minimum>
            </output>
            <output>
                <group>[Channel1]</group>
                <key>VuMeter</key>
                <status>0xB0</status>
                <midino>0x54</midino>
                <on>0x01</on>
                <minimum>0.4</minimum>
            </output>
            <output>
                <group>[Channel1]</group>
                <key>VuMeter</key>
                <status>0xB0</status>
                <midino>0x55</midino>
                <on>0x01</on>
                <minimum>0.6</minimum>
            </output>


I adapt the output port value, but the behavior of the Vu Meter leds are the same.

Note that It’s not possible in the DDJ-1000 to output an audio to the channels 1,2,3,4, when the device is used as “midi”, the mixer part for channels 1,2,3,4 are totally midi if the channel are not use as “external” (device). The audio output work only for Master, Booth and Headphone when the device is used as midi.

Can someone have an idea, how to map the Vu Meter ?

Well I figure out :D

The DDJ-1000 VuMeter Led trick work like this in Mixxx :

<off> : must be set to "0x00"
<on> : it is the VueMeter level. "0x00" mean the lowest level, and "0x7F" the highest -> Peak (red led)
----------> Note that the first led light at "0x40" when I experience it.
<minimun> - <maximum> : from "0" to "1" depend of the actual volume level of the playing track

Example :

Code: Select all
<!-- From volume level "0.5" to "0.7" first led in the VuMeter (0x40) is on -->
            <output>
                <group>[Channel1]</group>
                <key>VuMeter</key>
                <status>0xB0</status>
                <midino>0x02</midino>
                <on>0x40</on>
                <maximum>0.7</maximum>
                <minimum>0.5</minimum>
            </output>
<!-- From volume level "0.71" to "1" the top green led in the VuMeter (0x50) is on -->
            <output>
                <group>[Channel1]</group>
                <key>VuMeter</key>
                <status>0xB0</status>
                <midino>0x02</midino>
                <on>0x50</on>
                <minimum>0.71</minimum>
            </output>


So it is "large" values to see something significant (the Eurêka things...), it can be finest with middle school maths.
