My approach for live situations:
Tracks 1-4 are pad, synth, thru and sfx.
Tracks 5-8 : snare/clap, hat, kick, master.
Drum parts are improvised and created on the time of playing.
50% is blueprinted for what goes with what
50% is the chance to explore and make mistakes.
In a live situation, if a " mistake" is made, it provides the opportunity to wing it. The pressure of having the possibility of the inevitable is what keeps your decisions precise but also prepared to control a situation if it goes beyond your means.
