Hello community.
For what it is worth,
I do all the VSL programming with Cubase expression maps, and I do like to have all the articulations handy. I spent much time in building my own VI presets and in organizing the expression maps as efficiently as possible, with this very problem in mind (too many articulation slots fill the screen). So I made use of the 4 levels of intrication in the user defined articulations. Still in progress, but it works quite well. Here is my map for all dimension strings, and the screenprint of the Cubase lane showing it.
