I have been searching through this forum for some clues as to how to test Midi output of a plugin. Seems that neither the Plugin Host, nor the StandaloneFilterWindow classes have Midi ouput support.
There are threads pertaining to both these issues, with various people offering workarounds...
Yeah, should have explained it better. Midi output does work in the Host, but it’s just universal. There’s no midi out object like there is for midi in.
