The Pulse Width Modulator; The Metalizer - Arturia Microbrute User Manual

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

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
