OK, 4x users - can you confirm that the mic input can work simultaneously as the line inputs? This is huge for me - the manual says they are always active, the menu icon shows a routing pic that suggests the same, but the sound will not work unless I switch the audio input from "mic" to "line"
Users, please test this on your units, and tell me what I might be missing, thanks!

This is one of the only times I can remember that I was unable to bring a new instrument out on the job right away. Makes me sad that I can't.
