Would IExtendedSpeakerArrangement be equivalent to the VST2 behavior ?
Using VST2 and Juce, we used to declare a number of supported in/out configs, specifying only the number of channels, e.g., {2, 2}, {1, 2}, {6, 2}, {6, 6}…
Then the user could choose his loudspeaker layout directly in the plugin. That worked fine basically.
Would be nice to have a simple interface like this in VST3.
Thanks,
Charles
