> I have the delay/echo setup on fx3 and I want to use button 3 to mute the input of the effect. do I need to set the effect in a mute group?
I don’t have a CQ, but in the manual I find that I can assign to a softkey “Mute … for specific channels” and I would assume that it works the same with a single FX.
Perhaps you could test it on your CQ.
> I’m presuming that the default button choice of mute will kill the effect entirely and cut off the tail. I’m using fx3 as a long delay throw.
In the manual I see that I can choose a Mute Mode for FX:
“Set “Trails On” to hear any reverb or delay trail fade out naturally when muting an FX unit. Set Trails Off to have the FX mute instantly”
> is there a way to side chain a compressor on 2 guitar channels being fed by the lead vocal channel?
The manual contains a block diagram and there is no side chain for compressors – so I’m afraid it won’t be possible.
