STIPULATED (I do pay attention @Vortico) that Bridge is deprecated:
As far as I can tell, if you add a CV-MIDI module and specify Bridge as the type, it just doesn’t work. You can’t select a device, which makes a certain sort of sense, but I don’t think it actually passes MIDI out.
I tried it with Ableton, and while I can select the VCV Bridge VST as a midi source, nothing comes out of it.
I was curious why @midiguru23 was asking about using MIDI loopback drivers to do this.
Now more than ever, we need that Rack 2.0 VST!
