Chug-Chug: 

Summary: 

The sawtooth and wavefolded waveforms of

 neóni

 are mixed 

in lìon. The output of lìon as well as a stepped triangle waveform from 
Cš-L are further mixed via the input and inverting input of I-ō47. The 
low pass output of I-ō47 is sent through the bottom channel of vincâ.
The output of vincâ is sent through tanh[3]. A sub square waveform from 
Cš-L is through-zero frequency modulating and hard synchronizing 

neóni

. A sequencer or keyboard modulates the pitch of 

neóni

 and 

Cš-L. The sequencer or keyboard also triggers cèis. cèis modulates the 
cutoff frequency of I-ō47 and the level of vincâ. Because Cš-L through-
zero frequency modulates and hard synchronized 

neóni

, changing the 

frequency of Cš-L will change the pitch of the sound and changing the 
frequency of 

neóni 

will change the timbre.
