Can’t you program drum fills and such to be the cues, you know like the bands used to do 
I bet it will be nicer to perform when you feel from the music that the next part is coming, instead of looking for it at a tiny screen. And it might just be better for the audience too.[/quote]
Sorry - I wasn’t clear. What I’m saying is that I get caught up in the other aspects of the performance and end up failing to queue up the pattern change at the right spot. Or worse, I fat-finger it and switch to the wrong pattern.
I wouldn’t worry about it if I was just doing a DJ set on my own - but when the vocalist and drummer are depending on me to make the change at the same spot every time I am a lot more comfortable when it’s foolproof and I can focus on the other aspects of performance.
