Here is a link to a video of my Long Island-based 80’s band, The Breakfast Club, performing Voices Carry (by 'Til Tuesday). You can see my (new) laptop with Gig Performer to the right of me (my left).
I use Setlist mode and switch between song parts with one the three buttons on my Casio CTK-7200 that transmits midi. (I converted my preexisting Casio CTK-7200 (and PX350) to use as a controller keyboards, while still using their internal sounds where it makes sense to do so).
