FILTERS
Mode Meaning
Split Mode The lters are also routed in parallel with 2 poles each, but each lter receives a different set of
signals: Oscillator1 and the sub-oscillator are sent to lter1, oscillator2 (including FM), oscillator 3
and noise are sent to lter2. The ring modulator is disabled.
There is no difference between Serial 4 and Serial 6 if one of the “analog” lter modes is selected .
¦ Filter Balance
-64 to +63: Put as simply as possible, this is the relative contribution of each lter to the overall output of the
lter section. Actually a complex set of cross-fades, but the result is highly intuitive: At 64 you can only hear
the output of Filter1. At 0, both lters contribute equally. At +63 you can only hear the output of Filter2.
¦ Cutoff Link
Position Meaning
Off The lter1 CUTOFF knob only affects lter1.
On The upper CUTOFF knob also controls lter2. The lower knob (CUTOFF 2) becomes a bipolar (64
to +63) offset to lter1 cutoff instead of an independant value.
¦ Key Follow Base
C-2 to G8: The pivot-note for Key Follow. Notes below and above this point will be affected by Key Follow.
¦ Pan Spread
0 to 127: The stereo width of the Split mode signal i.e. the relative levels of the left and right signals. Pan
Spread also applies to Unison sounds, and is therefore mirrored in the Master edit menu. Modulation desti-
nation “Pan Spread“.
Only visible here in Split mode (see “Routing” above).
¦ Mode
Mode Meaning
Low Pass LP. Allows frequencies below the cutoff point to pass through i.e rejects those above the cutoff
point.
High Pass HP. Allows frequencies above the cutoff point to pass through i.e. rejects those below the cutoff
point.
Band Pass BP. Allows frequencies close to the cutoff point to pass through i.e. simultaneously rejects those
above and below the cutoff point.
Band Stop BS. Rejects frequencies close to the cutoff point (within a certain “band”) i.e. allows frequencies
above or below the cutoff point to pass through. Note that Resonance effectively narrows this
band, making the effect less obvious.
Note that lter2 does not offer “analog” modes.
¦ Key Follow
0 to 127: How much cutoff 2 follows the MIDI note and pitch bender.
Modulation destination “Filter2 Key Follow”.
¦ Env Polarity
Positive, Negative: The effect of Env Amount on lter2 cutoff can be inverted by setting this parameter to
Negative.
Common
¦ Routing
Mode Meaning
Serial 4 The lters are routed in series, with 2 poles each.
Serial 6 The lters are routed in series, lter1 has 4 poles and lter2 has 2 poles.
Parallel 4 The lters are routed in parallel with 2 poles each.
