well yes, there is no support for a DMXControl 2-like custom control panel anymore. But there is a reason for that. We have unified the access to device properties in the device control on the right side of DMXControl 3. Just select the fixture in the Stage View and the device properties will pop up in the device control. There is now also an inbuilt support for RGBx-Colors (e.g. RGBWAUV, lime, indigo etc.). So you now only specify the color-channel in the DDF and if needed the position in the color circle. DMXControl 3 then adds the color entry in the device control and a possibility to control the specified color. Slider and dropdowns are also supported in the device control. But they are now automatically generated according to the specified device properties. For example DMXControl 3 adds a slider for the amber property by clicking on the amber entry in the device control and the arrow on the right side of this entry. An example for dropdowns is attached. Just add a "rawstep" block in the DDF.
You are right, there is very few documentation especially in english. But we have now for a few months a DDF documentation in our german Wiki https://wiki-de.dmxcontrol-pro…index.php?title=DDF_DMXC3 It is not translated yet, but maybe it is helpful for you anyway to determine, how to specify the device properties in the DDF. And if you have any questions about that, just ask here in the thread / forum
Edit: The DDF for the Eurolite PS-4 HCL should be in a way similar to the DMXC3 DDF of the ADJ HexPar 5P RGBWAUV (12CH Mode). If you attach the manual / DMX address table then I can create a DDF for you. The other way would be you create the DDF and attach it here with the address table and I will review it for you
