Everyone knows that one of the greatest new features in Live 4 is the addition of MIDI. Another is the enhanced routing setup, and the two instruments, Impulse and Simpler, have caused a lot of excitement as well. But with all the hype these features have received, some may have missed what I find to be one of the most amazing additions to Live of all: Follow Actions. Anyone, from novice to pro, can see how MIDI support and virtual instruments make composition a snap, but the true beauty of Follow Actions may only be apparent to those deeply familiar with the use of Live as an improvising and rearranging tool. While the use of Follow Actions can take many (infinite?) forms, the rules that Follow Actions adhere to are few and simple. This means that once you understand their parameters, you'll be able to invent all kinds of new uses for Follow Actions on your own.
