If the sinusoid waveform of an LFO modulates the volume of an amplifier, the sound 
will increase in volume then disappear in a varying manner following the speed (the 

frequency) of this LFO. This will produce a tremolo effect. 

 

 

A sinusoid waveform on an LFO modulating the frequency of an oscillator would 
produce a vibrato effect. The frequency of this oscillator will thus be modulated up 

and down. 

 

 

With an LFO sinusoid wave modulating the cut-off frequency of a lightly resonant low-
pass filter, you will obtain a «wah wah» effect. 

 

 
 

 
 

 
 

 
 
 

 
 

 
 

 
 

 
 
 

 
 

 
 

 
 

 
 
 

 
 

 

 

 

 
Now to finish, here is the diagram of a complete synthesis voice on the CS-80V 
containing: 

 

 

1 oscillator (VCO) 

 

1 noise module 

 

1 mixer (mixing of the 2 VCO and the noise module towards the low-pass and high-

pass filters) 

 

2 filters (VCF) high-pass and low-pass 

 

1 amplifier (VCA) 

 

2 envelopes (one for the filters and the other for the VCA) 

 

1 LFO
