Sorry guys,
I should've posted my findings here because this really is a great tool that Randall does not clarify in the manual, (maybe a newer manual does?) :?
The manual I have DOES speak of each loop in detail and does mention each loop being "independent". However, I think a single line mention in any new manuals going forward that you can "use both simultaneously" would be helpful.
I guess it's kind of a "duh" thing since it does specify independence between the two, but even seasoned gear heads like myself sometimes like to have it spelled out by the manufacturer: "these two loops can be used at the same time" (within the parameters explained for each loop in the manual).
I was able to re-wire my rack and try running some simultaneous combinations, the tests were great and I'll be changing my Rig permanently based off my experiments. Had to order some more gear of course, to make it such.....but once it shows up, I'll make the switch for the long haul.
I LOVE the MTS heads....I've had a few glitches with them since switching from Engl heads last year, but the overall the flexibility with the modules, tubes, MIDI, and loops is outstanding 8)
