    Feedback Elimination
    For live use, i have my macbook doing all of my vocal effects through logic 8. I have had considerable problems with feedback and was wondering if anyone here knows of any plugins that i could use instead of my almost useless Sabine fbx2400 and the completely useless Behringer feedback "destroyer". Please take into consideration that we use heavy distortion, delay and reverb on our vocals. We also use Sure Beta 57a mics (that supposedly have the highest gain before feedback of any mic) and that we use NO onstage monitors. Any help would be great, especially considering we have not had one person point in us the right direction for years now. Thanks Ben

    Hi Ben, the first thing I can think of to cause that is if you have software monitoring on in your preferences. Should be by the 24 bit recording check box too. Make sure it's unselected. What's your soundcard to record it? Does it have a software mixer to control the channels? Check those for feeding signals in to each other or you may have multiple busses and one may be doing something long forgotten about! See what you find out. Cheers John

    Re: Feedback Elimination
    I am not recording, just direct monitoring, using logic as a live effects processor. The problem is coming from the effects. But all of the noise gates and EQing does not take care of the feedback problem created by the distortion, delay and reverb. So basically, all I am asking is if there is an AU Plugin that acts as a feedback eliminating device (like the ones stated above), and if anyone knows of any other tips or tricks for eliminating feedback in a heavily effected live vocal performance. thanks -ben

    Hi Ben, I'm still not sure I follow exactly. Software monitoring will impact direct monitoring as well as recording by the way, I was thinking more feedback generated from effects signals going back in to a mic going back out of your monitoring in to you mic etc. But from what I can gather, you're just chucking loads of feedback on to your signals and you want to tame it. Is that right? Reverb and distortion won't give any feedback by themselves unless it's from a scenario I outlined above. The feedback controls are in the delay plug in. There's no feedback eliminating device that I'm aware of, you just want to play with resonance, feedback threshold, delay time length and cross channel feedback.. off the top of my head. Noise gates will help create your own decay envelopes for sounds but if the feedback is heavy, the amplitude will not drop to a level for the noise gate to kick in rendering it pretty useless. Does this make sense?
