0 – None: The filter is bypassed and has no effect on the sound.
1 – Lowpass: The response attenuates high frequencies above a user-settable cutoff frequency, but lets low
frequencies pass through.
2 – Highpass:
The response attenuates low frequencies below a user-settable cutoff frequency, but lets high
frequencies pass through.
3 – Bandpass:
The response peaks at the cutoff frequency; frequencies above and below that frequency are
attenuated.
4 – Bandreject:
The response is reduced at the cutoff frequency; frequencies above and below that frequency
are not affected.
Cutoff (0 to 127)
This sets the initial filter cutoff frequency to which modulation can be applied. 0 is the minimum possible
frequency, 127 the maximum.
Min Cutoff (0 to 127)
Minimum cutoff sets a lower frequency limit. Example: With a lowpass filter response, bringing the filter
cutoff down below the signal’s lowest frequency will mute the sound. Setting a minimum cutoff frequency can
prevent this from happening.
Res (0 to 127)
Resonance creates an amplitude peak at the cutoff frequency (except in Bandreject mode), where it creates an
amplitude dip). The maximum resonance is set close to the point of self-oscillation, and will resonate
according to the frequency content of the waveform that is being filtered.
Dyn (on or off)
Enabling the ‘Dyn’amic option increases the overall resonance by dynamically scaling the Q (in addition to the
cutoff frequency of the filter) in accordance with changes of envelope and/or external control.
MIDI Control Section
Cutoff Controller
This parameter assigns a MIDI controller to provide real-time continuous control over the filter cutoff
frequency.
