Cutoff
Controls the influence of the mod wheel on the filter cutoff.
Osc1/2/3 Wave
These parameters control the influence of the mod wheel on the waveform of the
three main oscillators.
NOTE
These controls are only available if the selected oscillator type supports
waveform modulation.
Filter Section
Filter Shape
LP24, 18, 12, and 6 are low-pass filters with 24, 18, 12, and 6
dB/oct.
Frequencies above the cutoff are attenuated.
BP12 and BP24 are band-pass filters with 12 and 24
dB/oct. Frequencies
below and above the cutoff are attenuated.
HP6+LP18 and HP6+LP12 are combinations of a high-pass filter with 6
dB/
oct and a low-pass filter with 18 and 12
dB/oct, respectively (asymmetric
band-pass filter). Frequencies below and above the cutoff are attenuated.
Attenuation is more pronounced for the frequencies above the cutoff.
HP12+LP6 and HP18+LP6 are combinations of a high-pass filter with 12
and 18
dB/oct and a low-pass filter with 6
dB/oct (asymmetric band-pass
filter). Frequencies below and above the cutoff are attenuated. Attenuation
is more pronounced for the frequencies below the cutoff.
HP24, 18, 12, and 6 are high-pass filters with 24, 18, 12, and 6
dB/oct.
Frequencies below the cutoff are attenuated.
BR12 and BR24 are band-reject filters with 12 and 24
dB/oct. Frequencies
around the cutoff are attenuated.
BR12+LP6 and BR12+LP12 are combinations of a band-reject filter with 12
dB/oct and a low-pass filter with 6 and 12
dB/oct, respectively. Frequencies
around and above the cutoff are attenuated.
BP12+BR12 is a band-pass filter with 12
dB/oct plus a band-reject filter
with 12
dB/oct. Frequencies below, above, and around the cutoff are
attenuated.
HP6+BR12 and HP12+BR12 are combinations of a high-pass filter with 6
and 12
dB/oct and a band-reject filter with 12
dB/oct. Frequencies below
and around the cutoff are attenuated.
AP is an all-pass filter with 18
dB/oct. Frequencies around the cutoff are
attenuated.
AP+LP6 is an all-pass filter with 18
dB/oct plus a low-pass filter with 6
dB/
oct. Frequencies around and above the cutoff are attenuated.
HP6+AP is a high-pass filter with 6
dB/oct plus an all-pass filter with 18
dB/oct. Frequencies around and below the cutoff are attenuated.
