Send midi Tonality and scale information

Hello. I am working with the Quad Cortex to be able to work with the voice harmonies. I have already managed to incorporate a voice track with several effects but I would be interested in using the minivoicer effect, transmitting via MIDI the tonality and scale messages of the song I am playing so that the voice effects can adapt to that tonality.
Has anyone managed to transmit this Tonality and scale information to the quad cortex via midi?

Thank you
