Hi all. I have a show coming up where the lead singer also plays the whistle. They want to use the same mic for both vocals and whistles and they sing and play during the same songs. As you can imagine there is a totally different eq and compression between the two sources. I want to route the source mic across two channels and then use a softkey to toggle between the channels with one muted when the other is open and visa versa. The critical factor is that the change needs to be instantaneous and that there is no chance of having both channels muted at the same time. I can live with sitting on one softkey or toggling between two. Do I need to create two scenes and toggle between them with two softkeys or is there another way. thanks
