I could help you with that, in fact I just “released” the Toontracks’ Orchestral Percussion perc maps, so all those techniques are included, that is why it rings a bell to me… (available freely in another thread)
You could study how I’ve mapped them (because they are available in the first place, and what playback techniques I created)
One thing I don’t know is whether there is a better way to notate those different techniques. I admit that I created my own way of notating them that seemed logical to me but I would perfectly understand if it’s something that should be changed!
