This is a sound generator capable of producing low frequencies. On analog synthesizers, it is also called LFO(*1).

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)	Vibrato (voice, violin, etc.)
Vibration of Timbre/Sound	Wah Wah (woodwinds, etc.)
Vibration of Volume (AMP)	Tremolo (organ, electric piano, etc.)

To understand the LFO effect, let’s select the basic patch [PRESET D-8]once again.

Press [PRESET] Press [D] Press [8]

P ress the [DESTINATION1] button and select the target for the LFO

to process. Try the vibrato effect here by selecting PITCH1.

Y ou can switch the vibrato waveform by pressing the [SHAPE] button.

Additionally, turning the [RATE] knob will change the speed

of vibrato. Try out various settings for vibrato with different waveforms and speeds. For example, the human voice or a violin would typically have a vibrato rate of 2 to 7 cycles per second.

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.
