I’m not familiar with the chord pad feature, but here some general info:
The normal midi to track routing using the MG plugin, doesn’t reach modules of DAW’s that expect an external midi keyboard.
On macos it is easy to run the MG standalone with virtual midi output port: this will work just as external midi keyboard with a DAW: enabled midi input from MG will then enable MG as a midi keyboard.
Regrettably on windows, MG standalone via virtual midi is error prone because of ASIO often permitting only 1 connected app. if you want to try neverheless, use loopMIDI
