I like the idea of the feedback detection; however it could be better. At present it's difficult to create feedback while in the screen.
I run my monitor buses pre-fader; rendering the gain on the bus useless.
It would be better to include the source channel's strip along side the bus strip in order to adjust channel's volume. Otherwise you have to keep bounding between screens.
Additionally it would be beneficial to add an easy access dial for gain on the source channel.
Mainly, all elements elements involved should be included on the same screen.
Ultimately, you'd think Behringer would have included a feedback destroyer as a FX insert. I'll make that request. Seems simple enough to employ.
