The Function of Controls
Chapter LFO
( Low Frequency Oscillator )
4
This is a sound generator capable of producing low
frequencies. On analog synthesizers, it is also called LFO
T
o achieve expressive, animated sounds, many musical instruments are played with cyclic vibration
of sound frequency, volume, and/or timbre. LFO creates these effects for a synthesizer.
Vibration of Frequency (OSC)
Vibration of Timbre/Sound
Vibration of Volume (AMP)
To understand the LFO effect, let's select the basic patch [PRESET D-8] once again.

PCM Synthesizer
On the other end, with high-capacity wave memory, are synthesizers that authentically
reproduce acoustic instruments. These sample-playback synthesizers are useful for a wide
range of genres — from rock, pop, R&B, jazz, classical, and any other style that requires
accurate recreations of realistic instruments and sounds.
