Creating movement with the LFO

One way that I can add constant modulation to the signal that's periodic is using this LFO that's down here in the bottom. So an LFO is much like an audio-rate oscillator, like these ones above--the primary oscillator and sub-oscillator-- in that it generates a periodic waveform, so even some of the same types of waveforms: triangle waveform, square waveform. The difference is instead of sending to the amplifier so that we can hear the signal, it's sending a control signal. For example, I could assign this to modulate the filter cutoff.

And instead of it being like an envelope where it's a one-time deal, it's going to consistently modulate this cutoff in a periodic way. And I can set the rate with this Rate control here. So you can see that goes in hertz. Hertz are cycles per second, so it can be a fraction of a hertz, or it can go all the way up to almost 25 Hz. If we go the other direction with this, we can see its divisions of the beat, like quarter notes, dotted half n...
