Unlike the original CS-80 LFO where only the sine waveforms were available, the wave 

can be set with the «WAVE FORM» selector. The waveforms available are sine, saw-up, 
saw-down, square, noise and random. 

 
This LFO can function in three modes chosen on the «LFO MODE» selector: «FREE», 

meaning that all LFOs of each of the polyphonic voices function independently of the 
others; «TRIGG», meaning that the LFO restarts at the beginning of its waveform each 

time that the polyphonic voice is activated; and finally «MONO», where only the LFO of 
the first polyphonic voice is used. 
 

The latter allows us to bring a general effect to all of the voices at the same time, like the 
original CS-80. 

 
It is possible to synchronize the LFO speed with the tempo of the host application with 

the «MIDI SYNC» button. 
 

The signal from the oscillators then goes through two filters in a series, one high-pass 
and one low-pass. The cut-off frequency and the resonance of each of these filters can be 
set with the green and red «HPF» and «LPF» faders (above or below the labels).  

 

 

 

By clicking on these labels, it is possible to activate or deactivate a filter in order to save 

on calculation power. 
 

The «24dB» button lets us go from a 12dB filter to a 24dB filter. The two low-pass and 
high-pass filters are simultaneously modified. 
 

 

 
The filters are modulated by an envelope where the «IL» (Initial Level), «AL» (Attack 
Level), «A»(Attack), «D»(Decay) and «R»(Release) settings function in the following 

manner: 
 

 «IL» represents the start of the envelope relative to the frequency of the filter. The filter 
frequency will be modulated starting with a frequency inferior to the frequency setting. 

The more «IL» is increased, the lower the starting frequency will be.
