i am developing a plugin which does not support pure mono. So Cubase is loading a stereo version of it into the mono channel. Audio is fed only into the left plugin input and taken only from the left plugin output.
Now what I experience is that this works for VST but as a VST3 plugin the buffer on the (unused) right plugin channel is not flushed by Cubase/VST3/JUCE (don’t really know which one is the culprit). So audio is accumulating on the right plugin channel which due to the plugins algorithm also gets output on the left plugin channel.
Below you find a test plugin to demonstrate. The jucer file you just need to rename back from .jucer.txt to .jucer
Any idea what to do about it?
