Blofeld User´s Manual
Colour
-64...+63
Colourizes the noise signal. A value of 0 produces White
Noise while positive values lower the bass area. Negative
values dampens the higher noise frequencies.
The Filter Section
The Blofeld offers two filter that use the same parameters
for editing.

A detailled introduction of the filters can be found in
the chapter „Sound Synthesis Basics“ of this manual.
The most important controls of the filters can be found in
the Parameter matrix.

Filter Section Parameter Controls
Cutoff
0...127
Controls the cutoff frequency for the low pass and high
pass filter types, the center frequency for the band pass
and notch filter types, and the delay length of the comb
filter types.
•
When a low pass type is selected via the
Type
parameter, all frequencies above the cutoff
frequency are damped.
•
When a high pass type is selected, all frequencies
below the cutoff frequency are damped.
•
When a band pass type is selected, only
frequencies near the cutoff setting will be passed
through.
•
When a notch type is selected, the frequencies
around the cutoff frequency are damped.
•
When a comb type is selected, the frequencies
near the cutoff frequency are emphasized (comb+)
or attenuated (comb-).
You can bring more movement into the sound by
modulating the cutoff frequency via the LFOs, the
envelopes or the
Keytrack
parameter of the filter. At a
value of
64
and a
Resonance
value of
114
, the filter
oscillates with 440Hz, which is equal to A3 (the Comb+
type oscillates one octave higher). Tuning is scaled in
semitone steps. When
Keytrack
is set to
+100%
, the filter
can be played in a tempered scale.
