I see Nuendo calling prepareToPlay shortly before AND after starting audio callbacks. I added a lock which makes me very nervous but it’s only gonna get used once at about 3 buffers into processing.
Maybe your “bypass processing” bool is a safer idea, but it would mean outputting dry signal (or silence) for an entire buffer… or you’d have to check it before using every contentious object… but even that won’t be 100% safe.
