The Pulse Width Modulator (or PWM) takes the square wave and changes the 
ratio between the time the waveform is at maximum or minimum. The square wave 
corresponds to a 50% Pulse Width (PW). The pulse width can be set over a wide range 
(50% to 90%) making it possible to create a wide variety of tones from hollow and rich to 
nasal and thin. Figure 21. On the MicroBrute, the pulse width control can be controlled 
by the LFO, ENVELOPE or KEYBOARD CV OUT by patching it in the MOD MATRIX

The Metalizer takes the basic triangular waveform and “warps/folds” it to create 
very complex jagged waveforms that are rich in high harmonics. This results in “metallic” 
sounds that are ideal for harsher tones that fit well in dance music or lead sounds that 
need to cut through a mix. The Metalizer has a default connection to the ENVELOPE via 
the MOD MATRIX. By turning up the ENVELOPE AMOUNT control and turning up the 
METALIZER knob, you will hear the effect. It can also of course be controlled via the LFO 
or Keyboard CV. Figure 22
