Hello, Thanks again to all those who helped with my last question about "Ultimate Newbie Mistakes." Anyway, I ran into my first mixing problem: I am in the middle of my first mix on my 002 system/G4 setup. I will try to be brief but give enough info to convey how I got to where I am. I have a fairly simple song, since it is my first shot at mixing, and I created two different aux tracks for reverb, delay, etc... I bused my snare to the first aux for some reverb (using the "DVerb" included with the 002). Next, I added some compression to my bass (Waves Ren.). My guitars, at this point, did not need anything (at least I could hear). So far, so good. Punchy drums and bass. Clean guitars. Then I started tweaking with vocals. I needed a bit of a longer verb for my voice, so I bused my main vocal to the second aux, which has the same verb but a longer setting. Anyway, I started to notice a really odd ringing when I stop playback. It does not seem to do it during playback, but it is pronounced enough after stopping that the signal is showing up on all tracks which have some type of plug-in. Do I have some weird feedback loop going on? Maybe this is normal? How do I fix it? Does it even need fixing when I record to two tracks? Thanks for helping an extremely green noob!
