I’ve always been a bit confused why some plugin manufacturers (like UAD and Waves) provide mono versions of their VST plugins and most don’t.
The way channels are set up in Cubase, a mono audio channel always stays mono and a stereo channel stays stereo, no matter what plugins you insert. So I imagine if I insert a plugin in a channel it should just load the mono or stereo version, depending on the channel. And that’s what the plugins seem to do.
Or is it that they always load the stereo version and I don’t know it because the user interface in both mono and stereo looks the same?
I did some testing with the UAD plugins. I found that it makes absolutely no difference (in sound or DSP load) whether I use the stereo or mono versions on mono channels. Obviously using the mono version on a stereo channel is no good.
With the Waves, it’s a bit different because mono and stereo versions often have differing surfaces. So if I load a stereo plugin in a mono channel, the level meter on one side just stays at zero. But sound-wise there is no difference either.
So can I safely delete the mono versions and just use the stereo plugins?
