MIDI Outputs
You can create virtual MIDI destinations in Vezér's MIDI Preferences, output to that MIDI nodes which ones will be available as inputs in other apps - but you can send MIDI messages to any MIDI inputs. Destinations other then Vezér's dedicated outputs will be listed on the MIDI output popup.
For safety, if you select a MIDI destination Vezér will automatically disable it in the MIDI Input Preferences to disallow MIDI "short circuits" - because it could result in weird behaviours if you send MIDI from Vezér back to the app. However, you are able to re-enable that input manually.
OSC Outputs
Similarly to the MIDI outputs, you can create any number of OSC Outputs to send to, and its possible to assign different OSC Outputs for each Track.
Vezér can auto-discover OSC inputs of some applications which supports this feature.
Art-Net Outputs
Similarly to the MIDI and OSC outputs, you can create any number of Art-Net Outputs to send to, and its possible to assign different Art-Net Outputs for each Track.
