I setup 2 DMX tracks to see what was going on, because I noticed my lights were not doing what I had programmed them to do.
The first track output is going to VST’s DMX Mixer so that I could see what signal was coming from the automation track.
The second track output is going to the lights.
I didn’t check all 11 channels, but channels 1 and 2 on VST DMX mixer is doing the following:
Channel 1 on mixer is only going to 91 even though the automation track is set to 127.
Channel 2 on the mixer is only going to 5 even though the automation track is set to 7.
So, the higher up the scale I go in the automation track the greater the error in the mixer setting.
FYI, I am only testing with a single light with 11 channels. I don’t have a DMX terminator on the light (am waiting for it to be delivered) however this shouldn’t be a problem with a single light setup.
I did some further testing on this problem. The following was tested on Channel 1.
I created an automation track using the draw tools. The automation track was set to 255, but when I play the automation track back to the mixer and the lights it sends a 183 setting.
I tried recording the fader movements to create an automation track. I moved the slider all the way to 255, the automation track recorded 255, however when I play the automation track back to the mixer and the lights it sends a 204 setting.
That’s only the project. If a project uses assets (like DMX clips) you need to export your project as an archive. Use the function “Menu / File / Save Archive…”, select an empty folder, zip it and drop it here.
After spending considerable time trying to figure out a work around for this issue, I discovered the Volume control on the DMX Track is affecting the channel values but, in a logarithmic scale. You probably figured this out already, but as far as I know DMX does function like audio, the values are linear, not logarithmic.
The upside is I do have a workaround (although very sensitive). The volume control allows me to get the values close to what they should be.
Just tested version 3.0.20, the problem with incorrect DMX signal is still there, but now the workaround of using the Volume control on the DMX track no longer works so I cannot program anything above 183 on any DMX channel. I can select 255, but the system only moves to 183.
This is a real problem or am I missing something??
OK, I see what you’ve done. I don’t believe DMX was on the original mixer channels. I see how I can control the DMX output with it. If I set it to zero it sets the DMX output to the proper setting from the automation track.
