Ok, so I have been using this for a few years and navigate fairly well. Well, it seems that when I use Apogee to connect my instruments, I cannot get my Mics to work all of a sudden. I use phantom power, no help. I use line in, mic xlr, nothing. AND NOW my whole apogee control panel is grey and will not open up to let me select "software instrument, line mic -10" etc. I haven't touched anything unusual. Where do I start my trouble shooting? As of now, I cannot select the type of instrument or mic to use in control panel. But before that disappeared, I was still having trouble getting my mics to work, yet guitar was fine. HELP, this is sooo aggravating....seems like a ghost in the machine. What have I done wrong??
