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