How To Control DMX Lights From A Computer Using QLC+ and uDMX Adapters

[@mikelorenz4861]

It’s nice to learn how DMX works. I figured it was similar to MIDI. It seems the possible variations are pretty much limitless. Thank for your clarity.

HOLY CRAP I WAS SEARCHING FOREVER FOR A TUTORIAL ON THIS!!!! THANK YOUUUUUU

Cool. I had been trying out Freestyler2 software but this looks more suited to what I want!

[@kazemzahedi1047]

Hi Thanks for the great video. I have a set of DMX512 LED pixel lights. These are plane basic fixtures. Can I use QLC+ to set the address of the fixtures, before I can use them

[@trevor1564]

Is there a way to have the scenes fade between

[@Storytimewithallen]

Can you add music to the software?

[@lifebarier]

Hod do I make it react to music on its own? preferably not via microphone but 3.5 input or something?

[@DynamismImpulse]

SO.. about that end channel terminator?? How important is it?

[@showmanderek]

Great video. Thank you for the insight. I have a question regarding not know what kind or how many fixtures a particular venue may have. If I am creating a light show to run in sync with click tracks, how will i know that the show I create in QLC+ will work in every venue. For instance, if one venue has 16 ChavetSlim Par 56 fixtures, and 4 moving fixtures (name any brand and model) but the next venue has less, more, or even none.

[@TonyTascioglu]

Unfortunately, I don't think you can ensure that. You can prepare for the most you might encounter, but you'll have to do "patching" at every show to map the channels their lights are on to the fixtures on your show regardless.

[@CBR1100-d8q]

Thank u tony Can I add music with the program?

[@sirobellino]

Exploring different ways to control my dmx lights, this is by far the most simple technique. Just one question at 11:58 with the output, what exactly is "uDMX" referring to? the cable adapter? thanks.

[@ManuelSantofimia]

Thanks! I really learned how to set up the program. But when I run the show manager after creating different intensities in my light as you do, nothing changes! Do I have to do anything else in order to make it work?

[@johnkinghorn7427]

This video was excellent, thank you. I have a set up with several ADJ lights chained together, but up in the ceiling area of a hall. The first light has a DMX in leading to a port in the wall. Everything works perfectly, using 'lightkey' software and a simple DMX convertor box. However, when I close the software, and unplug the cable from the wall port, the first light turns on and stays a dark red colour. The light is too high to manually turn off. Is there a simple fix for this? The only way to turn the light off at the moment is through the master fuse box, which can't be a good thing! Thank you for any advice you can give

[@chacon1312]

Sometimes this can be a setting in the light itself. e.g. when it loses DMX value (computer powers off or cable is unplugged) it defaults to a red color. Worth checking if possible for you!

[@ambroise105]

Hi, is it possible to control lyre or par using bash command line? by using QLC+ ?

[@eldi]

Hi Tony, thanks for the guide. This is a step closer to what I want to do, but in essence I'd like to connect all of my lights, lasers etc., and I'd like to make them synchronize with each other - I assume I can do this through DMX and use my comptuer as the controller. But I would also like to download pre-built laser effects / shows for different lights, and then make the controlling unit take sound as input. Is this possible and how can I do this?

[@Anton-du-Fleur]

I have QLC+ 4 and a uDMX Lixada dongle . it says on input/output the System timer accuracy : Bad I am new to this can you suggest anything i can do? The install instructions with the disc not in english..... I have windows 11 on laptop

[@fabz1509]

Deserves a thumbs up. Very informative and fantastic money saver. However not sure why you went into hyper mode at around the 20 min. With such fast cursor movements? Got quite confusing. Something to be mindful for your future videos. Thanks again.

[@TonyTascioglu]

Thanks for the kind words! As for the hyper mode, I will try to keep it in mind for future videos!

[@dlgdlnrd]

Our school has already a DMX connector and lights built-in in our studio. I'm planning to buy the USB to DMX converter but it's way to short to connect it in the lights. Can I connect the DMX converter to the existing DMX cable? Won't there be any problems like delay or worst, a power shortage that could harm my laptop? Anyway, thank you for this video. I learned a lot and will be using this software. These kind of softwares really help a student like me with no budget and just starting with program lights.

[@TonyTascioglu]

It should be no problem to add a DMX cable between the adapter and the lights. You can extend it quite a bit before you run into signalling issues. Delay is inconsequential, electrical signals are basically the speed of light. Interference may be, since these USB devices don't have the strongest output, but I haven't run into issues (yet). If your school is older like mine was, you may need to convert the 3 pin DMX into 5 pin DMX - most dimmer racks are 5-pin vs new lights that are 3-pin . If so, you can solder yourself an adapter, the 5 pin signalling is the same, the remaining 2 pins are unused :) The main thing I'd be concerned about is if you have some no name cheap "LED Par" lights like the one I use in this video - I've seen the power supply of one of those fail which could have sent live AC power down the DMX port.

[@meinbherpieg4723]

Can you control scenes values using midi switch controllers? Ideally I'd like something i can stomp on while playing to activate a new scene.

[@TonyTascioglu]

Yes, I believe it should be possible, I believe you can map MIDI inputs to DMX outputs. A good starting point might be from the replies on www.qlcplus.org/forum/viewtopic.php?t=8457 or through www.qlcplus.org/old/docs/html_en_EN/midiplugin.html

[@allenpoling6854]

HI, I acquired a 2780 Laser show box that runs through a test mode of all the images line a running man, happy birthday, a shark, and many others. It has DMX and I have a USB to DMX cable. Can this box be controlled like a DMX light so I can pick individual images?

[@TonyTascioglu]

Probably - it depends on the light and what parameters it allows to be set over DMX

[@AlexandreGauvin]

Outputs on a mixer are actually male and inputs on a microphone female (mistake at 7:30). Not opposed as you say.

[@OffGridandOutdoors]

I'm sure I'm not asking correctly, but what do I need on a windows PC so that QLC+ can hear midi commands from a presentation program like ProPresenter 7? I know pp7 will send the command, and I know QLC+ can hear them, but is there some other software that needs to be running to let both applications (pp7 and qlc+) communicate on the same pc?

[@TonyTascioglu]

I know on Linux, Jack can route any MIDI application to any other MIDI application. If you're trying to essentially loop a MIDI device, I'm not sure how Windows and Mac handle it. You might be able to use something like this to create a virtual MIDI port for routing: www.tobias-erichsen.de/software/loopmidi.html

[@OffGridandOutdoors]

@@TonyTascioglu thanks I figured it out. Tobias Erichsen's little program running on a PC ... loopMIDI ... does the trick.

Unfortunately, I don't have a Mac, so I can't check if it works or not. You might be able to find responses on Reddit or somewhere if people have experience with it.

[@pickypete0]

I was about to install Freestyler...never heard of QLC which is better. i just got my dongle in and the instructions suck its a UDMX adapter from Amazon. this qlc seems to be easier if all you did to start up was what you showed

[@TonyTascioglu]

I remember using Freestyler back when I used Windows... I couldn't get it working on Linux though, hence why i switched to QLC. The setup on Linux is as I just showed it, it's pretty simple, and auto-detected. However, I have no idea how complicated the driver install is on Windows, if it's supported. Historically, these cheap adapters have had a questionable track record on Windows, sometimes requiring unsigned driver installs which I'd want to avoid...

[@johncuria]

Great tutorial! I'm having a 40'x60' steel building constructed to house my large audio system mostly comprised of JBL SRX series loudspeakers. Would like to start my retirement hobby by developing lighting effects tailored to specific audio recordings and have them synched during playback (automatically control the lighting when ever I launch the audio playback). Can the QLC program allow me to do that or would I need additional software/hardware?

[@TonyTascioglu]

As far as I know, yes. There's also other software more specialized to do music based light shows, Vixen comes to mind for example as I used it some years ago to synchronize Christmas lights.

Well, tutorial is good, but I'll keep my lights on auto mode as it seems too convoluted for me

[@anhellehna6858]

Excellent explanation!! 👍💯 I would like to connect the dmx lights directly to the computer. I actually use FL Studio for the music production. Is there any way to control the dmx lights with FL Studio? Which VST should I use? I tend to use DMXIS plugin inside FL Studio, but I am not sure if that would work. I find the automation in FL Studio very easy. Therefore, if possible, I wouldn’t change the DAW. Actually, I don’t know how I can use MIDI notes to control dmx lights. Is it possible in general? Then, how should I set the MIDI in/out settings to trigger dmx lights? Hope you could help me, because I don’t find any detailed source about that in the Internet. Wish you a nice day.

[@TonyTascioglu]

The naive way to do this would be MIDI out from FL-Studio, through loopback, into QLC. I know QLC works fine with hardware MIDI controllers, so it should be possible to do using software as well. You might need some software to act as a midi-loopback to send the output from FL directly to QLC. I found the QLC MIDI plugin page very handy to try to set it up, here is the link: www.qlcplus.org/docs/html_en_EN/midiplugin.html MIDI loopback on Windows if you need it: www.tobias-erichsen.de/software/loopmidi.html

[@kiyoshidev9781]

This is plug and play???, I saw Freestyler that it needs to set specific channels for it to work properly on generic lights.

[@TonyTascioglu]

The base functionality (if you know the DMX channels and have the drivers) is relatively plug and play. However, if you want to create proper features for all of these lights, then that definitely takes a bit of time to define the DMX channels and values - especially since they aren't very well documented for these cheap lights.

[@kiyoshidev9781]

@@TonyTascioglu Thank you for this info!

[@KWMATIK]

artnet gate is the best interface to QLC+ , any usb dmx512 is obsolete solution

[@TonyTascioglu]

While I agree that artnet is definitely more modern, getting such a setup is also very costly. One of the big selling points of using uDMX adapters is that if you're just starting out, it's a much lower barrier of entry.

[@CHGOfficial512]

you got it working? i got exactly same setup but i can't get working rgb, strobing and total dimming, only function selection works :(

[@TonyTascioglu]

Are the channels mapped in a weird way? I know some DMX lights (particularly more complicated ones) often have multiple DMX modes with different channels. I haven't heard of a 3 or 4 channel mode on these ones, but if there is a menu option, that might be a setting. On the other hand, have you checked that you're using the same DMX start address on both the computer and light? Seems weird that the channel for function selection would work but not the others...

[@CHGOfficial512]

@@TonyTascioglu I missed the fact that first channel is central channel since it wasnt in user guide. But after a while it suddenly cut off. Maybe i accidentally selected some option or it just overheated ( dmx module got pretty warm) So trying again tomorrow

[@Ben-d1i]

It says the app doesn’t work anymore I’m not sure why

[@TonyTascioglu]

As per the QLC+ website, it's still maintained and releasing versions, so you might want to try filing a bug report with the devs!

[@myleslux6983]

How come your QLC program looks so much different from mine? Making it really hard to follow this tutorial lol

[@TonyTascioglu]

Could be a few things, I used QLC+, not the C based QLC, and, I used the beta of QLC+ version 5, whereas if you install a stable release, it is likely still version 4. Aside from that, small UI changes are likely due to QLC+ picking up system themes.

[@julianklietz6558]

so, how important is a terminator now?

[@TonyTascioglu]

I'm pretty sure the rule of thumb is to always terminate a DMX connection to avoid random noise on the line (usually from reflections on the line) , though from personal experience, it's usually only be an issue if you're daisy chaining multiple fixtures. A terminator is surprisingly simple, just attach a ~120 ohm resistor between pins 2 and 3 on the final DMX output.

[@julianklietz6558]

@@TonyTascioglu Allright, the highest amount of fixtures i have ever driven at one time is like three. That might then be why ive never had any problems with noise and interference and such, eh?

[@ludvigbergsaker8745]

Could you make a tutorial on how to connect midi to qlc+ 5.0?

[@TonyTascioglu]

If you're on Linux, you can do this natively with JACK (or Pipewire). You can use QJackCtl's graph to connect any MIDI inputs to QLC.
