In this tutorial I explain how to send OSC (Open Sound Control) commands to QLC+ in order to activate buttons and sliders. Using Show Control software, you can play back audio cues, call up lighting cues (using OSC commands) and call up projection cues. As such you can synchronize and coordinate all the technical aspects of a performance.
QLC+ is an excellent open source lighting control program that works with Windows PCs, Macs and Linux. In this video tutorial I am using the Windows PC version 4.12.7. You can find more information about the program here: www.qlcplus.org/
Please consider donating to the creators as a program like this would cost several hundred dollars if it were not open source.
I also maintain a website for community theater techs where I provide some information and resources for controlling lighting, audio and using show control in theater productions. My website can be found here:

Thanks for the video, very helpful! I have a question, you mentioned you are using another laptop for the projections, which software are you using?

Hello When I did community theater I was using Microsoft PowerPoint. There were some issues with PowerPoint the main one being that it preferred video files that were in native windows format. (files with the .wmv suffix) Also it would sometimes balk at playing a slide with a video sequence out of order. Now that I am retired and more miserly, I use Apache Open Office. Their presentation program is called "Impress". It seems to work very well at video and still image slides. www.openoffice.org/download/index.html As projection becomes more and more important to theatrical productions, I have been looking into some ways to do projection mapping on a budget. I have found an open source program that allows you to do this and natively accepts midi messages so you can integrate it into your show control setup. The program is VPT8 which stands for Video Projection Tool version 8. The only downside is it has a steep learning curve and there are not a lot of tutorials available. You can find the program here: hcgilje.wordpress.com/vpt/ I hope to make some tutorials for it in the near future. Ed Richards

Amazing thank you! Would it be a similar process to using OSC triggers from a streamdeck or is midi easier?

Thank you Edward for your interesting tutorial. I am also involved in community theatre and have used SCS (Show Cue Systems) for years for sound and lighting. It is exceptional software for sound but if the lighting plot gets complicated it is difficult to manage on SCS thus the interest in QLC+. I am sending OSC commands to QLC+ from SCS and I know they are reaching QLC+ as the packets are being received but they do not register on the profile I have set up. I am obviously not sending the commands properly. I have tried the "/page1/start" command without success. I may not have the QLC+ page set up properly. Any help would be grateful.

Hello. I did some investigating and the problem seems to be with the format of the SCS OSC message. I used a OSC monitor program and sent an OSC message from the following show control software: CSC Show Control, Multiplay 3.0 and the demo version of Show Cue Systems. The OSC message I sent was /page1/button1 1.0 When I sent the message from CSC Show Control or Multiplay 3.0 the OSC Monitor shows me this - /page1/button1, 1f The"f" stands for float since I sent a decimal data value When I send the same message from Show Cue System the OSC Monitor shows me this - /page1/button1 1.0 Notice the missing comma separator and it doesn't indicate "1f" even though I sent a decimal data value I know that QLC+ does respond to the OSC message from CSC Show Control and Multiplay 3.0 I will send an email to the folks at Show Cue Systems to see if they have an answer to this. Meanwhile: You could use SCS to send Midi Note On/Off messages to QLC+ and control it that way. See my video about using CSC Show Control Midi Messages ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g3ytXCF_YBk.html Let me know if you need help with that. Ed Richards

Good news!! The folks at SCS gave me a solution. You need to use a specific syntax in your OSC message for example: /page1/button1 ,f 1 or /page1/button1 ,f 1.0 make sure there is a space after the locator (/page1/button1) then type ,f (comma f) then a space and either 1 or 1.0 I made a quick video for you to make sure you have everything correct ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-30e8rB-xSbA.html This should work Ed Richards

​@@edwardrichards7722 Hello Edward, I can't believe you went to so much trouble to make the video showing the solution. It works perfectly now with both the chaser or button/sliders. I must email you sometime to let you know what we are doing in Amateur Theatre here in Ireland. Kind regards, Seán.

Hi, quick question how can you send a OSC message from QLC to a console?
@edwardrichards7722
@edwardrichards7722 2 месяца назад
Hello I am a little confused by your question. QLC+ is a software lighting console so why would you need to send OSC commands to a hardware lighting console? If you want to send OSC commands to a hardware lighting console then you need to use show control software. QLC+ does understand OSC commands and it can send OSC feedback. For example: Using the "Touch OSC" app, I can design a remote interface that will send OSC messages to my computer running the QLC+ lighting software and so control various widgets in my QLC+ Virtual Console. These widgets can send feedback to the "Touch OSC" app to reflect whether they have been activated or changed. So a fader on my Touch OSC layout would be able to move a fader in my QLC+ virtual console. Also, if I move that fader in my virtual console, it would send a feedback message to my Touch OSC layout and so move that fader. Hope this makes sense? Ed Richards

Thanks for the answer now I actually understand why I couldn't find a way, and instead a show control software was what I was looking for
