Two FX Loops at the same time?

Having another blonde moment here guys.

I've been running my Cali76 and Revival Drive into the front of my Stage and a Stereo FX Loop with my BOSS GT1000 Core in it.

Now I want to move the Revival Drive into a mono FX loop before the amp. Every time I try this I get the message that there is already a loop in the rig.

Does this mean there is a one loop per rig limit?

Also every time I try to set a loop up I am told to use Send 2 and returns 3 and 4.

So what have I missed now?

Sorry about the questions. When I signed up for this trip I did warn you I'd be back picking brains...

Thanks, I’ll try that as soon as I wake up.

So much of the Kemper obvious and easy that I forget at times how much of a complex power house it is.

Worked a treat. I think the problem is that if a soft button isn't lit I've been ignoring what ever is below it considering it to be solely an "options available' indicator rather than an on off function.

Lesson learnt. Thank you.
