So there are four of us in my band. Keyboard/vocals, percussion/vocals, guitar, and bass. On some of our recorded tracks there are additional instrument lines e.g. banjo or synth. These are normally quiet brief lines maybe lasting a couple of seconds at most. We want to incorporate these lines into our live performances so are looking at a way to trigger them. We are hesitant to go down the road of bringing a laptop to our live gigs (mainly because it seems more likely for something to go wrong - although maybe this is misguided) so we began looking into hardware-based alternatives and came across the Roland SPD-SX sampling pad. This makes sense for us because the person best equipped in any given song to trigger these is most likely going to be the person on percussion.
Our main concern is ensuring that we play at the right tempo so that the samples are in time when triggered. The only solution to this that I can think of is using a click matched to the original samples. Is there any other potential solution to this? Also, is there any other alternative to the Roland SPD-SX that you would recommend? Appreciate any other info/tips on using samples like this live. Thanks in advance!
