> SATURATION
Saturation is the term used to describe the distortion effect applied to the output of filter 1.
Some types just add overtones, whilst others can be used to completely warp the sound
beyond all recognition. Saturation is always post-filter 1 and pre-filter 2, so you can use fil-
ter 2 to remove unwanted overtones if you like. Choose between the following types:
Off, Light, Soft, Middle, Hard, Digital, Shaper, Rectifier, BitReduce, RateReduce, Rate+Flw,
LowPass*, Low+Flw*, HighPass* and High+Flw*.
NOTE: Flw means that the amount of saturation applied will be adjusted according to the
MIDI note number (Keyfollow).
NOTE: *These last four options aren't really saturation effects at all, instead they are addi-
tional 1-pole filters.
> OSC VOL
Between values of –64 and 0, this adjusts the overall level of the 3 oscillators and the sub-
oscillator. From 0 to +63, this increases the level of saturation applied to filter 1. If Saturation
is set to Off, then values above 0 will have no effect.
> FILTER ROUTING
Determines the way in which the output of the mixer section is routed through the filters.
NOTE: The more poles a filter has, the more severe the filtering effect.
> Serial 4:
The output of the mixer section is routed through filter 1 (+saturation) into filter 2.
Both filters are 2 pole, with a 12dB/Oct slope. This results in a 4 pole filter with a 24 dB
slope.
> Serial 6:
The output of the mixer section is routed through filter 1 (+saturation) intofFilter 2.
Filter 1 is 4 pole, 24 dB/Oct, and filter 2 is 2 pole, 12 dB/Oct. This results in a 6 pole filter
with a 36 dB slope.
> Parallel 4:
The output of the mixer section is routed through filter 1 (+saturation) and filter 2
simultaneously. Both filters are 2 pole with a 12 dB/Oct slope. In this configuration, the sat-
uration applied to filter 1 is not affected by filter 2.
