Highpass (HP)
Click the button under the HP label to engage the highpass filter. The highpass filter is
a 2 pole (12 dB/Oct.) design. A Highpass filter reduces the level of frequencies that fall
below the cutoff frequency. It is useful for situations where you would like to suppress
the bass and bass drum in a sample, for example, or for creating classic highpass filter
sweeps.
Bandpass (BP)
Click the button under the BP label to engage the bandpass filter. The bandpass filter is
a 2 pole (12 dB/Oct.) design. A Bandpass filter only allows the frequency bands directly
surrounding the cutoff frequency to pass. Frequencies which fall outside these
boundaries will be cut.
Drive
This knob allows the filter input to be overdriven. Turning Drive up leads to a more
dense and saturated signal, which introduces additional harmonics.
Cutoff
Adjust this knob to set the cutoff frequency of the filter. As you turn this knob to the
left, an increasing number of high frequencies are filtered from the signal. The Cutoff
value also serves as the starting point for any modulation involving the filter.
Resonance
Turning up Resonance leads to an emphasis of the frequency area surrounding the
frequency defined by the Cutoff parameter. Very high Resonance values introduce self
oscillation, and cause the filter to produce a sound (a sine wave) on its own.
Simultaneous Control of Cutoff and Resonance
Click and drag on the chain symbol located between the Cutoff and the Resonance
knobs to control both parameters simultaneously: vertical mouse movements alter
Cutoff, and horizontal mouse movements affect Resonance values. This way you can
experiment with different filter cutoff and resonances while maintaining the
relationship between the two parameters.
