12/24DB MULTI MODE FILTER
The resonant 12/24dB lo/hi/band-pass filter gives control of both the low and high filter cutoffs. Its flexi-
bility can make it function as a variable gap bandpass filter as well.
MULTI MODE FILTER MAIN
BASE sets the base cutoff frequency of the fil-
ter. Sweeping this parameter with WIDTH set
to the max value makes the multi mode filter
act as a high pass filter.
WIDTH controls the distance between the low
pass and high pass cutoff frequencies. When
BASE is set to its minimum value, sweeping
this parameter makes the multi mode filter act
as a low pass filter.
Q controls the amount of resonance applied to
the cutoff frequency or frequencies set in the
multi mode filter SETUP menu.
DEPTH controls how much the filter envelope
affects the cutoff frequency or frequencies.
Negative values invert the envelope.
ATK sets the attack time of the filter envelope.
DEC sets the decay time of the filter envelope.
MULTI MODE FILTER SETUP
HP sets the high pass filter slope. Select
between 12 dB or 24 dB.
LP sets the low pass filter slope. Select
between 12 dB or 24 dB.
ENV selects which parameter the filter enve-
lope will affect.
HOLD controls whether the filter envelope
should be affected by the HOLD parameter of
the AMP MAIN page or not.
Q selects how the resonance will affect the cut-
off frequencies. It can affect the BASE,
WIDTH, both of them or none.
DIST sets the headroom of the filter. The
higher the value, the lower the headroom.
