We’ll investigate this.
MG has worked with Studio One for Mac for a decade, and nothing changed on our side for several years. But sometimes we see DAW updates unintentionally break things, and fixing it again in another update, as they become aware.
Apple Silicon has shaken things up a bit and of course we’ll make sure it all works. MGv3 will be Apple Silcon native, as is the MINI version that was intended as a temporary workaround until MGv3 is out.
There is some misinformation in your comments (VST1, MG AU doesn’t send out MIDI), but thanks for editing it.
