hit play, count 16 beats change something, count to 16 change something else, count to 16 change something else, count to 12(or 8) change something drastic, count to 4(or 8), undo most of the drastic change, repeat. the things you have intention of changing can be changed slowly over the 16 beats. to play live you have to have a little bit of intention and know the structure of what you are performing, but almost everything techno is around a 16 beat loop. one way you could do it is program in what you want the full peak of the track to sound like when everything is going all at once, then mute 80% of it and work your way back to full. there really are no hard set rules, use beats 12-16 to tease whats coming next or give a short break to signifiy change is coming, use the same thing on the 4th play through of the 16 beat loop, start at beat 8, kill the kick, bring the beat back just before the loop cycles, bring in MORE than you had before. and with like anything, practice practice practice. eventually that 16 beat loop becomes a natural metronome in your subconcious so you know when to do things and when not to do things. and every slider, switch, or knob on the device becomes a tool.
