BossGuitar69 In practice, monitoring your live audio signal through mobius is not exactly obscure, but from past comments, it is most often not used. This is because it is better when possible to monitor your live signal "direct" rather than all the way through the computer to reduce latency. All Mobius needs to do then is receive that audio and delay it, and play it back but you're not depending on it for your main signal. If you are not using other plugins in the host to process your instrument sound but rather using hardware amp modelers or mutli-effects, this is what you want to do. If that's your situation, then most audio interfaces have some mechanism for direct monitoring in addition to passing the audio into the computer.
If you ARE using other plugins in the host for your instrument sound, then even then people seem to usually use host routing to effectively split the signal from the audio interface into two chains, one for effects processing and one for looping, but there is a lot of variability on that. For example, post processing the Mobius output "wet" mixed with the "dry" live signal.
For simpler signal chains of Audio Interface->Plugin Host->Amp Modeler->Mobius->Audio Interface then yes, through-Mobius monitoring is convenient and should be presented more visibly.
For others reading this I'm curious, how many monitor through Mobius?
