be adjusted with the PWM & Metalizer knob in the front panel’s LFO section.
Triangle and Metalizer
The level of the Triangle wave and Metalizer is controlled with the
slider potentiometer labeled with the Triangle symbol. Pulling it down
completely mutes the signals and moving it up increases their level.
Turning the Metalizer knob from fully counter-clockwise to fully
clockwise warps the triangle wave’s smooth, flute-like sound into
complex, metallic-sounding waves. The wave warping/folding is also
under the control of two modulators: the Filter envelope, the polarity and amount
of which can be adjusted with the ENV Amt knob; and the LFO [4.2.6], the polarity
and amount of which can be adjusted with the PWM & Metalizer knob [4.2.6.4] in
the front panel’s LFO section.
The sub-oscillator (Sub Osc)
The Sub-oscillator level is controlled with the slider potentiometer
labeled Sub Osc. Pulling it down completely mutes the sub-bass
signal and moving it up increases its level. The Sub Osc Section
contains two toggle switches. The Wave switch selects the sub-
oscillator’s waveshape, which can be either a square wave (grinding
sub-bass sounds) or a sine wave (deep mellow sub-bass sounds). The
Octave switch sets the sub-bass to either one octave (-1) or two octaves (-2)
below the oscillator’s pitch.
Noise
The signal mixer also provides the control of other signals which aren’t
generated by the Oscillator. The Noise slider potentiometer adjusts the
amount of white noise signal sent to the filter. Mixing a small amount of noise
with oscillator waves creates a kind of breathing, natural quality. For example,
mixing the Triangle wave with a small quantity of noise creates a credible flute
sound. Noise is also useful on its own to create various special effects or
nature sounds such as wind, water streams, and rain, as well as percussive sounds
such as cymbals.
Audio In
The Audio In slider potentiometer adjusts the amount of an external audio
source (guitar, microphone, etc.) that can be plugged into the MiniBrute
signal chain via the rear panel Audio In jack [4.3.3]. This makes it possible to
process an external audio signal with the filter and amplifier; also note that
this signal can trigger the envelopes.
