So if I understand you correctly... I'm going on a witch hunt!!! Thank you for the info I'll have plenty to research and a direction to travel. there's definitelynot much room in there. I did find another reason to want this feature as well. I bought a Zoom H5 to help record ideas when I'm just noodling around. with this feature I could feed the loops through the aux and record it all together instead of using multiple cords to input the different channels. Well with the ADAM casing being so large maybe the ultras can get bigger qith more features. But at what point have you added it all but the power amp? And what price difference would make you buy that over the amp?
