Microfreak/UG/07 Filter/01 Modifying Sound/04 Cutoff Frequency
07.01.04 Cutoff frequency
- The cutoff frequency is where filtering takes place. Feeding a filter's output back into itself creates a resonance peak around the cutoff. The Resonance knob controls this effect; the LFO or envelopes can also modulate resonance when assigned in the Matrix.
- Filters attenuate frequencies gradually above or below the cutoff. This slope, or roll-off, depends on the number of poles: a four-pole filter has a steeper roll-off than a two-pole filter. The MicroFreak filter rolls off at 12 dB per octave.
- The Cutoff knob moves the cutoff point from about 30 Hz at its fully counter-clockwise position to above 15 kHz at its fully clockwise position.
