Right now i´m trying to get to use feedback assistant to help with feedback on two mics and one guitar, and unfortunately the feedback assistant is only available for the whole output mix of mainLR or the AUX outputs.
Therefore in theory i can´t have specific frequencies cut for specific instruments, but specific frequencies cuts that affect all of the mix.
I found a workaround using a smal jack to jack cable in which i rout the output of a channel to one aux(aux1), then connect that oux to another input(input16) and therefore then i can use out1 as a feedback processor and input16 for the rest, yet if there was a chance to route AUX1 to MainLR i would not need to use a jack jack cable which also makes me effectively use two channels for one voice input.
Besides that all of the rest is great and having seen some of the suggestions i 100% agree with getting a high contrast version, in the daytime when playing outdoors it´s pretty hard to see.
Thanks!!
