Featuring automatic on-the-fly compilation of the script, ability to insert variable and function names into the code by pressing Ctrl+Space in the code editor(*) and, finally there’s the ability for me to add script “factory” presets. (The factory preset shown in the video is a bit lame, but I will try to come up with some cool ones for the next release. Stuff like the pitch sequencer thing shown in the video.)
(*) This should be a lot nicer, but it’s a bit tricky feature to do as well as you may know from things like Visual Studio or Qt Creator coding IDEs…

Looking forward to this feature! Laurie Anderson, would be proud 😀
What do I need to wright the scripts? Knowing C++, etc.? Or is it a matter of knowing the “formulas”?
Basic understanding of programming (using variables and arrays) and math (to do something meaningful with the variables via operators and functions) are needed. The eel2 language (by Justin Frankel/Cockos/Nullsoft) used isn’t very complicated. There are no functions that can be defined in the program code itself, no classes/objects, no types besides “numbers” for the variables etc. Note that this feature of course isn’t in any way something one *
must* use, it’s just there to allow results that the GUI knobs and envelopes might not be able to do.
