@dannytaurus JPverb and Greyhole Reverbs developed by Julian Parker have been moved to MIT licence some months ago (don't remember the exact date...) after discussion with Julian himself.
im guessing after ableton, logic, cubase, and reaper--
fl studio and studio one are the next 2 you should test with.
and looks like a fl studio trial can test thirdparty plugins, but studio one you woudd need a pro license or subscription. But I havent tried those 2 so I could be wrong.
@Christoph-Hart Awesome,
Primarily interested in the accessibility side, but a little confused about delivering future expansions and whether or not I need to send expansions to NI for approval... - or if it's just the initial functionality/integration...
