I've been recording vocals with magix for a long time. I think my first one was 7. I just recently bought 15 and still also use 10. Before I was using a Logitech computer mic that always worked with no problem. I then tried a M-Audio mic. That when this first happened. When I plugged it in Magix stops playing music so I have no way of telling if I'm on point with my vocals. It will record though, only I have to unplug my mic to hear what I recorded and ofcourse it's not on beat. So I returned that mic just thinking it was a mic issue. Now a year later I forked out more money and got a AKG Perception 220 mic, and I'm having the same issues. I also have a brand new dell laptop that I tried it with, and its the same thing as my desktop. I don't have an interface for the mic, I use a usb splitter so the mic can plug into my comp. I'm not really sure what a interface does. So maybe that's the problem. Or is it that Magix doesn't except these higher grade mics. I really dont have the money to spend on Logic or Cakewalk and Magix serves my purposes. Please tell me how to resolve this issue.
