Using Gig Performer for keyboard (General MIDI/internal patch) changes

Hello! Please forgive me if I lack any proper terminology needed to explain things. I was interested in using Gig Performer as an alternative to Mainstage, mainly, using it to control patch changes for my MIDI-connected keyboard. My question is this -

I believe that it is possible to use the program to change sounds that are used with a MIDI keyboard. I was wondering if it is possible to use or set up an environment where I can use Gig Performer for internal (keyboard-specific) patch changes. I use a Hammond SKX Pro that has both factory patches, user-created patches, and General MIDI.

Thank you for your time and consideration!

It is possible. Please check out these blog articles:
