● LOW FREQUENCY OSCILLATOR (LFO) - The LFO produces various
patterns of cyclical change. Applying the LFO to the pitch component produces
vibrato; applying it to the filter component produces wah-wah; applying it to the
amplifier component produces tremolo.
● CONTROLLERS - Controllers such as the pitch and modulation wheels,
aftertouch, and optional foot controllers can be used to control the sound in a
variety of ways. Some controllers such as the pitch bend wheel can directly
determine the pitch. You can assign the various other controllers to control many
aspects of the sound. For example, you might assign aftertouch so that the
amount of vibrato (LFO modulation to the wave component) increases as you
apply pressure to the keyboard after the initial attack.
