maybe a little strange that my first post is not a problem, but I want to introduce you to tools. If it doesn't fit here, let me know, but I think it's ok since the tools are open source (GPL-3.0). Last year I was allowed to do the tech for a very technical play (classical musicians, Reaper, TouchDesigner, Kinect and of course GrandMA3).
After a while I came across the program Chataigne, which was the perfect glue for me. Since then I use Chataigne to get Midi, OSC or other triggers into GrandMA3 and build my timecode sequences in Chataigne.
The other tool is a small step sequencer, which I use to control the lights in a club to electronic music. At some point it was too monotonous for me to push faders to not so much changing music and for me this is the possibility to go a bit deeper into the music. My working title for the tool is SLPS. Feel free to let me know if you have feature requests
