It would be nice to be able to have Manycam accept MIDI messages to do certain things. For example: Sliders that can control volume input levels, buttons that can switch presets, etc.
Third party MIDI-to-keystroke apps can accomplish some of this, but it’s clumsy (eg. converting a MIDI button’s signal to a virtual “alt+1” keystroke to change the preset).
It would be very useful for those using mixers or keyboards in real time environments.
