LFO
A slow, repeating wave — sine, triangle, saw up, saw down, square, or sample-and-hold — that you plug into almost any knob in the patch to make it move on its own, in time with the music if you like.

What it does
LFO is a modulator: it makes a moving value that can drive any control on the canvas. It takes control signal in and gives control signal out.
Try it
Sync an LFO to a quarter note and wire it to a filter's cutoff for an automatic wobble.

Controls
Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
