This function uses a two-pole lowpass filter to give you a sharper transition in bass response
than PARA BASS. Like PARA BASS, there are control-input pages for cutoff frequency and
amplitude, which are identical to those for PARA BASS. There is also a control-input page for
resonance (also known as “q”), which can boost or cut the amplitude of the partials near the
cutoff frequency.

You’ll get the best transition in bass response with a resonance setting of -6 dB. There’s a small
frequency range above the cutoff frequency where the response reverses direction (if you’re
cutting the amplitude, for example, you’ll get a slight boost just above the cutoff frequency). The
higher you set the resonance, the larger this reversal will be, resulting in unusual—but possibly
useful—response curves at high resonance values.
