GCPro+ 2GCX+ DSP-256XL+Gmajor: I can't controlling Gmajor

[Alvaroxxx]

Hello, I have 2 GCX Audio switcher, the Digitech DSP-256XL and Gmajor TC.
The connections are:

GCpro midi out to the pedal in the GCX-1
GCX-1 midi out to midi in of GCX-2
GCX-2 midi out to midi in the DSP
DSP midi thru to MIDI IN of GMajor

I control everything but that does not let Gmajor change and controlling the presets and no how.
Can anyone help?

Thanks

Does the G-Major show any MIDI activity when you press Ground Control pro buttons? What MIDI channel have you set the G-Major to respond to, and is the Ground Control set to send on that same channel?

The midi gmajor not active and is in the same channel. If the site change with the Digitech gmajor, the gmajor only change to the preset 4 and digitech is not active

I think you are saying that if you swap the two processors so the MIDI goes to the G-Major first then to the Digitech, that then the Digitech stops responding? If that is the case, try changing out the MIDI cable between the Digitech and the G-Major.

What MIDI channel do you have set for each processor within the Ground Control Pro? What patches are your Ground Control Pro presets programmed to recall on each processor?
