Hi,
i checked it with my own plugin and the plugin example.
getNumInputChannels() returns 2, even when its used as a mono plugin.
With an older version of the vstwrapper, cubase provided two valid pointers, so this was not a problem, now it delivers only one.
I’m not sure, maybe it has to do something how isOutputConnected/getSpeakerArrangement is handled inside the plugin.
Best regards
