@sowylie: what does an LFO do? here's a non-technical explanation i made for no reason. synth stuff all being named with acronyms (in this case, low frequency oscillator) is a fine way to describe what is actually happening sonically, but it can be tough for people to wrap their minds around until you really get used to synthesis. anyway, if you see the letters LFO on your synthesizer or in your music software and weren't totally sure what it was, now you know what it does. go try it
