I’m having problems with midi events (note-ons, note-offs, controllers) being intermittently dropped (not received by the plugin) on AAX Windows (32 and 64 bit versions). The problem is specific to AAX Windows. AAX Mac works fine as does all other formats (RTAS, VST, AU). I have tested under PT10 and PT11 dev and prerelease builds.
I notice that in the juce_AAX_wrapper.cpp process() function there is this comment:
// (This 8-byte alignment is a workaround to a bug in the AAX SDK. Hopefully can be
// removed in future when the packet structure size is fixed)
I don’t know if that might be related.
