That's not what I said,
I mean , you can send for example Stereo Guitar -> XLR L&R outputs / Backing tracks L&R-> Jack L&R outputs / Click -> Send 1 Output
Then send all to the mixer which have Aux outputs I presume.
Each Bandmember have his/her own aux dedicated and can make his own mix with what is connected to the mixer.
With the mixer you can simply have the click in the Aux Outputs and put the volume to 0 to frontstage
(excuse my english)
