Anyone doing a virtual sound check routinely at each gig? Next week will be my first gig with our new XR18. I'll be setting everything up, running sound from the stage, and playing guitar and singing, so I'll have plenty of things to worry about. More than likely I'll just use my iPad to get the mix right out front with my bandmates playing, and then blend in my guitar and vocals as best as I can with feedback from friends in the audience. On the other hand, by laptop is going to be there anyway, so it occurs to me that I could record a song with all of us playing and let us all listen out front together. Pros/cons? Pitfalls of which to be aware?
