FILTER

TYPE (Filter Type)

is is used to select the lter type. e resulting sound will be dierent depending on the selected

lter type. For LPF, HPF, BPF and BRF, the digits at the end of the lter name (6, 12, 24) indicates the

lter characteristics (dB/oct). e larger the value, the more abruptly that the lter will cut o the

sound at the cuto frequency.

LPF 12, LPF 24:

is cuts out the parts of the sound which are higher than the cuto frequen-

cy. Low Pass is the most common type of lter, and is used to make bright timbres sound darker.

HPF12, HPF24:

is cuts out the parts of the sound which are lower than the cuto frequency.

ese lters are eective when the low end is too strong, or when you want a thinner sound.

BPF6, BPF12:

is cuts out all parts of the sound, both highs and lows, except for the region

around the cuto frequency. Because of this, the sound can change dramatically depending on

the cuto setting and the Operator’s sound settings. With low resonance settings, you can use the

Band Pass lter to create telephone or vintage phonograph sounds. With higher resonance

settings, it can create buzzy or nasal timbres.

BRF6, BRF12:

ese are also called “notch lters” because of the dip in the midrange levels.

Only the parts of the sound at and directly around the cuto frequency are cut o. Try modulat-

ing the cuto with an LFO to create phaser-like eects. is lter type–also called a notch

lter–cuts only the parts of the sound directly around the cuto frequency. Try modulating the

cuto with an LFO to create phaser-like eects.

LPF MS-20, HPF MS-20:

Both of these are 12dB/oct lters that can self-oscillate and replicate

the distinctive tonal character of the Korg MS-20. If the input level is high, raising Resonance will

cause increasing amounts of saturation and overdrive, creating a more aggressive tone.

LPF Poly6:

is is a 24dB/oct lter that can self-oscillate, which replicates the powerful yet

sweet tonal character of the Korg Polysix.

ENABLE

Switches the lter eect on/o.

CUTOFF

Sets the cuto frequency of the lter in Hz. As explained above, the cuto frequency eect will dier

depending on the type you select. e range of most lter types is from 6.489 Hz to 23.68 kHz, but

the range of the MS-20 LPF/HPF and LPF Poly6 is from 12.98 Hz to +21.10 kHz.
