Let me try this again... I don't think I was clear enough.
The Stereo Effects Loop uses"Direct Output / Send" and both "Return Input" and "Alternative Input".
In the manual:
1) Like the Monitor Cab Off feature, the KEMPER Kone mode is only available for the MONITOR OUTPUT, as well as for the built-in power amp and is dedicated to your personal monitoring. The other outputs are not affected by these features.
2) If you select the option"Monitor Stereo", MONITOR OUTPUT and DIRECT OUTPUT become one logical pair of stereo outputs.
This tells me that if I enable Monitor Stereo in order to use two Kones in stereo, the "Send" necessary for my effects loop is gone.
The loop is absolutely involved if your goal is to use both a Loop and stereo Kones because that one jack can only do one thing at a time.
Seems like a giant oversight - not allowing the main outputs to send to Kones. I mean - not everybody uses the main outputs to send to FOH.
Unless there's a software patch coming, this seems to be a non-starter for using Kones in a stereo rig with stereo effects in the loop (including the Mimiq doubler, the rotary speaker effect where I can control the ramp rate and engage the high speed via envelope control, the Lexicon Vortex and any other stereo gizmo I feel like using.
