OSCILLATOR
The oscillator and its signal mixer
The oscillator delivers three basic waveforms: sawtooth, pulse, triangle wave and our
new PLL Overtone oscillator. The bottom row of knobs on the oscillator are the level
controls for each waveform. The upper row of knobs are waveshaper controls for
each of the waves. The MicroBrute allows you to blend and mix the different
waveforms to create more complex sounds.
Saw and Ultrasaw
The level of the Saw (sawtooth) waveform is controlled with the knob
labeled with the saw icon. Turning it counter-clockwise completely mutes
the signal, while turning it up increases the level. When the Ultrasaw knob is
fully counter-clockwise, only the saw signal is audible. Turning this knob
clockwise mixes more Ultrasaw sound in with the plain saw signal. The
Ultrasaw consists of two copies of the plain saw; these can be modulated
by patching the LFO to the SAW control in the MOD MATRIX. The phase shift
of one copy is modulated at a constant rate (.5Hz), while the second
copy’s phase shift modulation rate can be controlled with the SAW CV
input
Square and Pulse Width
The level of the Square wave is controlled with the knob labeled with
the square symbol.
Turning it down completely mutes the signal and moving it up increases
its level. When the Pulse Width knob is fully counter-clockwise it creates
a 50% square pulse. Turning the Pulse Width knob clockwise transforms
the square wave into an asymmetrical pulse whose width can be
increased up to 90%. The pulse can also be modulated using the LFO,
Envelope or Keyboard by using the PWM patch point in the Mod Matrix.
