Polarizing Mixer

The polarizing application resembles the mixer. The difference is the possible inversion of the signals. New 
shapes can be created when mixing for example LFO- or VCO-waveform-signals in- and out-of-phase.

VC-Mixer

By including the channel’s 

CV IN

r

, the mixing proportion can be altered dynamically. Thus you can create 

lively sounds using CV- or audio-source at the channels’ 

INPUT

q

.

Ring Modulator

In case two continuous signals with consistently changing positive and negative amplitudes (waveforms) are fed 
into inputs 

CV IN

 

r

 and 

INPUT

 

q

, ring modulation will be applied. Ring modulation will multiply two signals 

including their harmonics, creating sums and differences. This can result in pretty complex signals. While the 
use of sine waves often leads to results being usable in a musical way, waveforms with stronger harmonic content 
usually lead to disharmonic signals. In audio applications, ring modulation is often used to create metallic and 
atonal sounds.

The signal being present at the 

INPUT

 

q

 connector is the carrier, while the signal fed to the 

CV IN

 

r

 input is the 

modulator. To achieve mathematical correct results, set
