I'm using it to control Vienna Symphonic Library's Synchron articulations. Do not use SoundFlow, but have an Elgato StreamDeck XL and StreamDeck+. Using Avid's Pro Tools API and KeyboardMaestro to detect which track is selected, and automatically change pages of articulations on StreamDecks (XL for articulations for the relevant track, + for context-sensitive knobs based on selected articulation. Working well so far.
