5.4.3. Resonance
This knob lets you create a resonance peak at the cutoff frequency. Turning it clockwise
emphasizes the partials at the cutoff frequency, and the sound becomes more aggressive.
When the knob reaches its last quarter zone, the filter starts to oscillate on its own. However,
this oscillating behavior depends on the cutoff frequency; the MiniBrute 2S filter oscillates
within a range beginning around 180Hz up to approximately 8kHz. To extend the oscillation
range, use the Brute Factor knob.
5.4.4. FM knob
The FM knob lets you control the amplitude and polarity of the envelope signal sent
to modulate the filter cutoff frequency. At the middle position (12 o'clock), no envelope
modulation occurs. When turned counter-clockwise (below the center), the FM knob sends
an increasing amount of the inverted ADSR envelope. When turned clockwise (above the
center) the FM knob sends an increasing amount of the standard, positive-going ADSR
envelope.
: If you do not hear the effect of a negative-going filter envelope, try raising the Cutoff frequency.
Conversely, if you do not hear the effect of a positive-going filter envelope, try lowering the Cutoff
frequency.
5.4.4.1. ADSR (the filter envelope)
The letters "ADSR" are silkscreened under the FM knob because this connection has been
pre-wired for you. However this connection can be bypassed through the patch bay [p.58].
The ADSR Envelope [p.0] is covered extensively in the Basics of Synthesis [p.46] chapter.
