a great example and maybe a possible source of inspiration for this articulations feature, in my opinion, could be the amazing SkiSwitcher and ARTzID
http://www.skiswitcher.com
the key feature is that articulations get "embedded" inside the notes themselves, instead of being triggered by messages or keyswitches.
Hope this could be of any help...thanks for your amazing work Schwa!
All the best!
