So, for me, I found myself waiting on the screen. Which in a cover band, means everybody else, band, crowd, also has to wait. At the time I didn't realize that the audio was actually changing instantly. So I would hit the foot switch, turn my volume down, and wait for the change...and apologize to my band mates
The whole band is waiting for what? We are talking about milliseconds. If we finished one song i step one performance higher. Slot 1 is autoloaded and after the drummer has started the next song i could have changed the performances ten times. Or do you play a complete show instantly without talking to the crowd or a ten seconds break between the songs?
