12 dB Lowpass (LP 12)
This type of lowpass filter is also widely used in analog synthesizers (Oberheim, early Korg synths etc.). It has a
gentler slope (12 dB/Octave), leaving more of the harmonics in the filtered sound compared to the LP 24 filter.
The darker curve illustrates the roll-off curve of the 12dB Lowpass Filter. The lighter curve in the middle represents the filter
characteristic when the Resonance parameter is raised.
Bandpass (BP 12)
A bandpass filter cuts both high and low frequencies, while midrange frequencies are not affected. Each slope in
this filter type has a 12 dB/Octave roll-off.
The darker curve illustrates the roll-off curve of the Bandpass Filter. The lighter curve in the middle represents the filter
characteristic when the Resonance parameter is raised.
