with low resonance settings. The 24 dB lter modes attenuate the ltered frequencies to a
much greater degree than the 12 dB modes. The Ladder and SVF lters provide additional
lter architectures.
Filter Frequency (Freq)
This de nes the center or cutoff frequency of the lter. Note that
the resulting frequency may also be modulated by note velocity and by the lter envelope.
Filter Resonance (Res)
This de nes the resonance around the lter frequency of the lowpass
and highpass lters, and the width of the bandpass and notch lters.
Envelope / Filter Switches
These switches toggle the display between the lter's envelope
and its frequency response.
Filter Frequency<Velocity (Freq<Vel)
Filter frequency is modulated by note velocity ac-
cording to this setting.
Filter Frequency<Key (Freq<Key)
Filter frequency is modulated by note pitch according
to this setting. A value of 100% means that the frequency doubles per octave. The center
point for this function is C3.
Filter Envelope Rates<Velocity (Time<Vel)
This parameter exists for lter, pitch, LFO and
volume envelopes. It is therefore listed in the
section on envelopes
.
Filter Frequency<Envelope (Envelope)
Filter frequency is modulated by the lter envelope
according to this setting. A value of 100% means that the envelope can create a maximum
frequency shift of approximately 9 octaves.
Shaper
This chooser selects the curve for the lter's waveshaper.
Drive
This boosts or attenuates the signal level being sent to the waveshaper.
Dry/Wet
This adjusts the balance between the dry signal and the signal processed by the
waveshaper.
LFO Shell and Display
LFO On
This turns the LFO (low-frequency oscillator) on and off. Turning it off when it is
unused saves some CPU power.
