Brute Factor
The Brute Factor feature drastically alters the filter characteristics so
expect highly unpredictable results at extreme settings. You have
been warned!
The Brute Factor is a special MicroBrute feature inspired by a common
patch used on a famous vintage mono-synthesizer that connected the
headphone output to the external audio input. The result is a kind of
feedback loop that’s ideal for raspy and grungy sounds. This patch has
been implemented internally to the MicroBrute, and is controlled by the
Brute Factor knob.
This knob’s normal position is fully counter-clockwise, which disables the Brute Factor;
turning up the knob gradually adds distortion to the sound. For low Brute Factor settings,
the distortion is smooth and gentle but becomes harsher as you turn up the knob. When
turned up above about 75% of the way, the MicroBrute can go berserk and produce
barely controllable, crazy feedback sounds.
ENV Amt (envelope amount)
The ENV Amt lets you control the amplitude and polarity of the
envelope signals sent to modulate the filter cutoff frequency. At the 0
position (12 o'clock), no envelope modulation occurs. When turned
counter-clockwise (below the 0 mark), the ENV Amt knob sends an
increasing amount of the inverted ADSR envelope. When turned
clockwise (beyond the 0 mark) the ENV Amt knob sends an increasing amount of
the standard, positive-going ADSR envelope. This effect is additive so as you add
ENV amount, you may need to turn the filter cutoff down to get the desired effect.
