The current wrapper implementations seem to completely omit the processMode field when calling into the setupProcess/process functions, hence the field is always set to kRealtime (0) in all formats but VST3 even when the processing is taking place in an offline/prefetch context.
Can I expect a proper implementation in a future version of the SDK? I really need that feature in order to detect whether my plugin is running in a non-realtime context.
For now we support only the Offline processing information for VST2 (Vst2Wrapper::updateProcessLevel ())
I put it on the todo list for a next SDK version for AUv3, AU and AAX
