•MFB HP 24dB
A multiple feedback (MFB) highpass filter with a 24dB/octave slope.
! Be careful when using this filter type as high Resonance values could generate quite extreme audio levels!
K35 LP 12dB
An “early MS-20 type” of lowpass filter with a 12dB/octave slope. The filter can be driven to self-oscillate.
! Be careful when using this filter type as high Resonance values could generate quite extreme audio levels!
Reso
D Set the resonance amount.
In the SVF Notch filter, the Reso knob controls the width of the notch - from wide to narrow.
Freq
D Set the cutoff frequency (for the HP and LP filter types) or the center frequency (for the BP filter type).
Frequency Modulation
D Turn the Kbd knob to set the keyboard tracking amount.
At 0% the filter is static and doesn’t track the keyboard at all. At 100% the filter tracks the keyboard 1 semitone
per note.
D Click the Frequency Modulation Source box to bring up a menu of the available modulation sources.
The “Inverted” sub-menu contains inverted variations of all modulation sources.
q Use one of the Envelopes (see “The Envelopes section”) as modulation source to create a Filter envelope.
D Set the modulation amount with the Frequency Modulation Amount knob.
D Turn the Velo knob to control the Frequency Modulation Amount from Keyboard Velocity.
q If you want other modulation sources or scaling options, use the Mod Bus, see “The Modulation Bus section”.
