Topic: How can I send Midi signals with Points of Interest in Virtual DJ?

This topic is old and might contain outdated or incorrect information.

Hello,

I have lights and a DMX controller for them. I'd like to be able to add Points of Interests in a song, and when the POIs are reached during playback, a signal is sent to a midi controller, which sends the signal to the DMX controller, which triggers a new light scene.

How can I do this?

Thanks

I understand your logic but wont work .Keep in mind that DMX software support MIDI IN ( physical buttons pushed, sliders moving etc). So even if you send "signal" from VDJ to a MIDI controller, all you will do is to light up some leds, not to push any button ;)


I got the Chauvet Obey 70, and I have a Chauvet Swarm 5 FX and Chauvet Scorpion FX RGB. Is my best bet just to program Chases for particular songs, then hit those Chases as the song starts? Or is there a better option? Because that limits the number of songs I can do this for, and if I mis time it at the start, I'm screwed. Plus, it only cycles through the Scenes at the speed of the sliders, so I'll have to manually set them before each song starts.

You can do this, but it's a lot of trouble if you don't have any "programming" experience.
VirtualDj CANNOT send RAW MIDI data to a MIDI device.
Therefore you will have to define the MIDI device as a MIDI controller.
Once you define your MIDI device as a controller you can control it's "LEDs" through VirtualDj. In order to achieve your final goal you'll have to create a mapper for your device that uses variables to control the leds.
Finally you control these variables through your POI's

It sounds complicated, doesn't it ?

Example:
POI:
type=action, action=repeat_start_instant 'StartFunkyChase' 10ms 2 & toggle "$Chase1"
Mapper:
key=LED_CHASE1 action=get_var '$Chase1'
Device definition:
<led note="0x17" name="LED_CHASE1" channel="1" />

What happens here is that once the POI is triggered, MIDI note 0x17 (in HEX, which is 23 in decimal) will be triggered to ON and then 10ms later to OFF.

Now, if your DMX software is using this note to start a chase (and the MIDI mode is set to gate, not toggle) then the chase should start.
