On one end, a laptop-based performer has the option of simply playing a polished, premade audio file that she or he prepared in the recording and editing studio. On the other end, the performer can be creating sound completely from scratch using software-based synthesizers, sequencers, etc. Somewhere in the middle is where the majority of performance setups fall. Incredibly popular is the software tool Ableton Live. This gives a laptop-based performing artist the ability to sequence and trigger software synthesizers, external MIDI-controlled instruments, and internally stored sampled audio clips and loops. This can all be achieved in real-time, with the resulting audio being manipulated by Ableton Live's mixer and effect processors.
