SUBTRACTOR SYNTHESIZER

106

D 24 dB Lowpass (LP 24)

Lowpass filters lets low frequencies pass and cuts out the high frequencies.

This filter type has a fairly steep roll-off curve (24dB/Octave). Many classic

synthesizers (Minimoog/Prophet 5 etc.) use this filter type.

The darker curve illustrates the roll-off curve of the 24dB Lowpass Filter. The lighter

curve in the middle represents the filter characteristic when the Resonance parameter is

raised.

D 12 dB Lowpass (LP 12)

This type of lowpass filter is also widely used in analog synthesizers (Ober-

heim, 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.
