I have been struggling to get my new rig to do what I want. I am running a Marshall JMP-1 preamp, a bunch of pedals, and an Eventide Timefactor into a GCX Audio Switcher, and that is all being controlled by a Ground Control Pro. Everything was functioning exactly as I wanted, but once I tried to integrate the Timefactor (I have it connected to the MIDI out of the JMP-1, which is connected to the GCX Midi connector) it ceased to do what I want.

Here is an example: For bank 0-1 I had a clean sound with the JMP-1 (patch 00 on the Marshall LED), and I wanted to use a light reverb (bank 1-2 on the Eventide). Whenever I select that by manually selecting the bank on the delay and the patch on the Marshall, the Ground Control Pro memorizes the Marshall patch fine, but not the eventide. If I use the edit feature on the Ground Control Pro, then I can switch the bank on the eventide, but then it changes the Marshall Patch at the same time. I don't want it to do that.

I am clearly new to MIDI, so go easy on me, but is what I want possible? I tried to create a separate MIDI device channel for the Marshall and the Eventide each, but one seems to be controlled be the other regardless of how I wire it, or what I ask it to do. Any help is appreciated.
 
The Eventide is receiving what midi channel? If you can give it a midi channel that is different from your JMP1 then go into the GCP in settings and scroll down to Bank 2, Bank 1 should be the JMP1, and select the same midi channel number. After you save and exit when you program a preset button under the edit function you should see JMP1 and can choose which midi number then go down (Bank2 could be named Eventide) and choose the midi number for the effect you want. If you go down again you should see GCX 1 and be able to choose the pedals you want. Save and exit and when you push the preset button all should work.

Set the JMP1 to a mid channel
set the eventide to a midi channel
turn on GCX1
 
Yep, Marshall is MIDI channel 1, Eventide is 2. They are still affecting each other whenever I try to adjust one. I suspect it may have to be something adjusted on the Eventide's end (it has a MIDI menu which I tinkered with after 2 frustrating hours. That led to another frustrating hour of accomplishing nothing.)
 
I dont know about the JMP1 but could it be sending a Midi signal to the eventide also? if you unplug the midi into the JMP1 from the gcx and just have Midi out to midi in on the eventide does the JMP still change channels on the eventide?
 
I think I figured it out. The JMP was the problem. I had to set the channel to 1 on the JMP, the guy who helped me set my rack up initially had it set to OMNI, so it was responding to my attemps at controlling the Eventide only. Thanks for the help!
