Basic Synthesis Model—LFOs
The effect of a low frequency oscillator (LFO) applied to various elements of a synthesizer, first with a constant LFO and then with the LFO amount controlled by the modulation wheel. There are four segments to this video:
1) when applied to pitch it creates vibrato,
2) when applied to amplitude it creates tremolo,
3) when applied to the cutoff frequency of a low pass filter it creates wah-wah,
4) when applied to the center frequency of a notch filter it changes the middle of the note's spectrum.
