The duo I’m half of has used a beat-buddy for a couple of years now, using drum tracks the other half created in Cubase. It’s worked well and we always do a proper sound check at every gig. We are currently creating some additional backing tracks, played by us, to beef up the overall sound. But it’s a cautious approach as I don’t want to appear just another karaoke act. There are more than enough of those around already.
