An LFO (Low Frequency Oscillator) provides repeating waveforms (usually between .1 and 250Hz) that may be used for control and timing in voltage-controlled modular synthesizer applications. LFO's are generally used to create slow modulations such as vibrato and tremelo in electronic music equipment. see also moog
I'm trying to patch the LFO through the modulation bus and into filter bank but I don't have enough 1/4" cable!

LFO (Low Frequency Oscillation) is an effect in music production hardware & software which limits the amount of output of a bass, synth, etc at a desired speed which produces a wavy-like sound.

Definition for wider audience:

Since I started using the LFO effect in Reason 5 my beats now go WOMP WOMP WOMP

A electronic and techno music group. The name is based on the Low-Frequency Oscilator that they use in their music. The group formerly consisted of Gez Varley and Mark Bell, but now it is just Mark Bell.
LFO's last album was in 2003. I really wish they made another.

One of the worst boybands I've ever seen and heard. No longer exists.
LFO member: I like girls that wear Abercrombie and Fitch.
Fag: I'm a girl! I wear Abercrombie and Fitch! Do you love me?
LFO members: Oh no. Our cover's blown.
(They then run away like girls)

And I like girls who chew Copenhagen and SPIT! *Dry heaves, Loogie snorts, and spits*
Use this on someone who loves the LFO group.
