Introduction
FILTER ROUTING
The final parameter we’ll discuss 
for the time being is FILTER ROUT-
ING. This feature offers several fil-
ter routing options which allow 
you to operate the filters in series, 
i.e. patch one after the other in the 
signal chain, or in parallel, which 
means side by side in the signal 
chain:
SER-4    The filters are switched in 
series; with two poles each (12dB/
Okt.), both filters have the same 
slope for a total of four filter poles 
(24dB/Okt.).
SER-6    The filters are switched in 
series; Filter-1 has four poles (24dB/
Okt.), Filter-2 has two poles (12dB/
Okt.) so the overall slope is equiva-
lent to six poles (36dB/Okt.).
PAR-4    The filters are switched in 
parallel and feature two poles each 
(12dB/Okt.).
SPLIT    The filters are switched in 
parallel and feature two poles each 
(12dB/Okt.). Additionally, they 
receive independent input signals 
(more on this later). Each of the 
two oscillators routes its signal 
into one of the two filters whose 
signals can be spread in the pan-
orama via a parameter called UNI-
SON Pan Spread.
