Similar to my setup. I may be able to help. Firstly connect the FI midi out to the hub midi in. When you change chanel on the FI the hub should switch channels also. This will check the connection between the FI and the hub. As the connection between the switcher and FI seems to be working.
Another thing to check is that you have scanned pedals. By pressing and holding one of the buttons on the hub.
With this type of setup, it's usually acceptable to have everything run on the same chanel. Use the looper function to switch pedals on and off.
Thanks, I tried that & it does work until you turn everything off then the hub seems to forget what you told it to turn on and off.
Not sure where the issue is!
I've just received an email from the looper manufacturer telling me how to program the looper to send out the commands assigned to each switch on a seperate midi channel, so I'm going to set the FI to Channel 1 & Hub to channel 2 to see if that helps.
