Do AU PlugIns work in CUBASE 11 in any way ?
I believe this is a no, but with Apple Silicon losing VST2, it would be nice if 12 did. Steinberg releases its own instruments as AU.
How is cubasis handling that? (sort of a cubase for ipad)
I dont think apple will allow VST on ipads, least not if it going to be shared upon different vendors. And Apple will apply the same rules on Mac when ever they have the opportunity. For example plugin vendors that sell their stuff for both Mac and ipads can’t do VST. And for small plugin vendors the app store is appealing.
