Highpass -> Lowpass
In this mode, the Lowpass and Highpass filters are connected in series and both sets of
Lowpass and Highpass parameters are exposed and independently editable to create the
overall filter response. The maximum rolloff slope of each filter is limited to 24dB/
octave in this mode.
In Highpass -> Lowpass mode, the effect does not place any limitations on the
Frequency parameters of one filter relative to the other. In normal use, the Highpass
Freq parameter will be less than the Lowpass Freq parameter, creating a bandpass-type
response:
However, if the Highpass Freq parameter is greater than the Lowpass Frequency
parameter, the passband effectively disappears, since the part of the spectrum which is
above the highpass and below the lowpass is non-existent. As a result, you'll hear a
rapidly attenuating bandpass response as the corner frequencies diverge.
Note that while the Highpass -> Lowpass combination appears the same as the Band
Pass filter, this mode is different in several important respects:
• The rolloff points are independently adjustable as individual frequencies rather
than specified as a combination of center frequency and bandwidth.
• The rolloff slope of each High and Low filter can be specified separately while the
Bandpass and Band Cut filters use the same slope.
• The Resonance of each High and Low filter can be specified separately while the
Bandpass filter uses the same Resonance at high and low corner frequencies.
Highpass || Lowpass
In this mode, the Lowpass and Highpass filters are connected either in parallel, and
both sets of Lowpass and Highpass parameters are exposed and independently editable
to create the overall filter response. The maximum rolloff slope of each filter is limited
to 24dB/octave in this mode.
In Highpass || Lowpass mode, the effect does not place any limitations on the Freq
parameters of one filter relative to the other. In normal use, the Highpass Freq
parameter will be higher than the Lowpass Freq parameter, creating a bandcut-type
response:
