Straight from the Big Knob manual:
When you have a 2-track recording device connected to both the inputs & the outputs on the Big Knob, you run the risk of creating a feedback loop. If the recording device is in record, record pause, or input monitor mode, the signal can go from the 2-TRACK outputs through the the recording device and back into the 2-TRACK inputs, creating a circular loop that results in a terrible howl. You must remember to turn off the 2-TRACK INPUT SOURCE SELECT button when recording to your 2-track recorder!
Now, it also shows to run main mix outputs from the PC audio interface to the DAW MIX Input source inputs of the Big Knob. Then, connect stereo outputs from the Big Knob into main stereo inputs of the PC audio interface.
So, would this not cause an automatic feedback loop everytime you tried to record or arm record anything in the DAW? You'd have outs from the interface -> big knob & then outs from the big knob -> interface.
How could you ever record anything plugged into the Mackie Big Knob source inputs to the computer through the audio interface if the manual says not to, because of feedback loop?
Would the following routing cause a feedback loop?:
Interface Main Mix 1/2 Stereo Outputs -> Big Knob DAW MIX Input Source Stereo Input
Big Knob stereo DAW OUTPUT -> Interface Main Stereo Input 1/2
Stereo synth connected to Big Knob Source A Inputs
Turntable connected to Big Knob Phono Preamp Inputs
How could I monitor, play-live & record my stereo synth and/or turntable while backing audio is playing from the PC without causing feedback loops?
There has to be a way to mix all the audio coming from the PC, along with whatever is connected to the Big Knob, otherwise, why would it even have inputs?
