what software should I use?

The question is a little more broad than what software should I use.
I am in an acoustic three piece. I play percussion, there is a guitarist and a singer. We need to fill some background or create some background ambiance. I would be controlling the digital sounds so it would need to be something that I could have timed out and start it at the beginning of the song/set or something with buttons that I could press/hit/etc while playing. Would ableton live be something I am looking for with a midi controller or something? I am pretty new to the digital music idea but not new to computers. Any help would be appreciated!
