Can you clarify what is requested?
There is a utility called MIDI TCP driver that will create a virtual MIDI port on a Mac. The Qu/GLD/dLive mixer will send and respond to MIDI messages on this port, including simple Program Changes for Scene recall. While this doesn’t address MIDI integration with physical MIDI equipment (such as external FX mentioned by Steph), it works with software based DAWs, plugins or show control software. There is no need to use hex code on the computer side when running the MIDI TCP driver. e.g. a program change to 0 in Qlab will recall Scene 1 on dLive etc.
