MS-20 LP and HP: ese 12dB/octave, self-resonating lters lovingly recreate the distinctive timbral signature of the
classic Korg MS-20. Raising Resonance will cause increasing amounts of saturation and overdrive, creating a more
aggressive tone. Input volume can have a strong eect on this character; for more information, see “Gain” on page 31.
Polysix: is 24dB/octave, self-resonating low-pass lter provides the strong, sweet sound of the classic Korg Polysix.
Cuto
[-4.00 or +8.00…+136.00 or +138.00 semitones]
is controls the cuto frequency of the lter, in semitones mapped to MIDI note numbers (60.00 = middle C). e
frequency in Hz is also shown. e specic eect of the cuto frequency will change depending on the selected Type, as
described above. Most lter types have a range of -4.00 to +138.00, but the MS-20 LP/HP and Polysix range from +8.00
to +136.00.
Resonance
[0.00…100.00%]
Resonance emphasizes the frequencies around the cuto frequency, as shown in the diagram below.
When this is set to 0, there is no emphasis, and frequencies beyond the cuto will simply diminish smoothly.
At medium settings, the resonance will alter the timbre of the lter, making it sound more nasal, or more extreme.
At very high settings, the resonance can be heard as a separate, whistling pitch.
Low Resonance
High Resonance
Trim
[0…100]
is adjusts the volume level at the input to the lter. If you notice that the sound is distorting, especially with high
Resonance settings, you can turn the level down here.
Out (Output Level)
[0…100]
is controls the output level of the lter.
