CHAPTER 6
Synthesis Parameters
-  RATEREDUCER  Continuous reduction of
the digital sampling rate; generates digital
aliasing. 
-  RATE+FLW  The RateReducer with keyfol-
low; the sampling rate follows the played
pitch.
-  LOWPASS  1-pole low-pass filter for moder-
ate processing of high frequencies. 
-  LOW+FLW  The low-pass filter with keyfol-
low; the cutoff frequency follows the played
pitch.
-  HIGHPASS  1-pole high-pass filter for mod-
erate processing of low frequencies. 
-  HIGH+FLW  The high-pass filter with keyfol-
low; the cutoff frequency follows the played
pitch.
To reiterate the point, the amount of distortion,
intensity of the DSP effects, and the cutoff fre-
quencies of the 1- pole filter are controlled via
the OSC VOL knob.

FILTER ROUTING
This feature offers four filter routing options
which allow you to operate the filters in series
or in parallel:
-  SER-4  The filters are switched in series; with
two poles each (12dB), both filters have the
same slope for a total of four filter poles
(24dB).
-  SER-6  The filters are switched in series; Fil-
ter-1 has four poles (24dB), Filter-2 has two
poles (12dB) so the overall slope is equivalent
to six poles (36dB).
-  PAR-4  The filters are switched in parallel and
feature two poles each (12dB).
-  SPLIT  The filters are switched in parallel and
feature two poles each (12dB). Additionally,
they receive independent input signal s (more
on this later). The stereo position of the sig-
nals can also be manipulated via the parame-
t e r   T W I N   M O D E   PA N   S P R E A D   ( s e e
appropriate section) in the EDIT menu.

Regardless of which FILTER ROUTING option
you chose, the SATURATION stage is always
post-Filter-1.
KEY FOLLOW FILTER 1/2
Determines the extent to which the filter fre-
quency follows the pitch (Note Number) and the
Pitch Bend. Depending on the FILT SELECT
setting, KEY FOLLOW affects the first filter, the
second filter or both filters. The function uses C
1 (MIDI Note Number 36) as a neutral starting
point or base note: Regardless of the KEY FOL-
LOW value, the filter frequency is not influenced
