Gcx switcher

Hi!!! I am new here, my question is. ¿It is possible to control the GCX Guitar Audio Switcher with other devices? like a zoom g9.2tt

The GCX responds to MIDI Control Change messages 80-87 for Latching and 104-111 for Momentary on MIDI channel 16. A data value of 64 or higher will activate a loop and a data value of 63 or lower will deactivate a loop. In order to have preset style control, your controller will need to be able to send a string consisting of all eight Control Change messages. Check the manuals for your controllers, or contact the manufacturer to find if these message types and behavior are possible.
