Sound Parameter
Blofeld User´s Manual 70
Polarity positive / negative
Determines whether the feedback signal is fed back into
the delay line as is, or is inverted beforehand.
Cutoff 0…127
Dampens the signal produced by the Delay effect. This
filter is routed before the feedback circuitry meaning that
adjacent taps of the Delay will be dampened further. This
creates the typical “high frequency loss” that often
happens in natural echoes. A setting of 127 means that
the signal isn’t filtered, while lower settings filter the high
frequencies of the feedback signal.
Reverb
w
This effect type is only available for the Effect 2 unit.
The Reverb effect is probably the most widely used effect
in music production. It is used to add a realistic ambience
to clean and dry audio recorded in a studio. Very
complicated mathematical algorithms are needed to
simulate the complexity of a natural reverb. As a result,
good reverb processors are very expensive. The Blofeld’s
reverb effects don’t intend to simulate the perfect natural
room, rather they are an addition to the Blofeld´s sound
synthesis to make it more 3 dimensional and expressive.
HighPass 0…127
Determines the frequency where the lower frequency
parts are divided from the effect signal. This parameter
works in the same way as the highpass filter in the
Blofeld´s sound synthesis. A natural reverb doesn´t
produce all frequencies equally so the highpass cuts the
lower frequencies to produce a more realistic reverb
effect.
LowPass 0…127
Determines the frequency where the higher frequency
parts are divided from the effect signal. This parameter
works in the same way as the lowpass filter in the
Blofeld´s sound synthesis. A natural reverb doesn´t
produce all frequencies equally so the lowpass cuts the
higher frequencies to produce a more realistic reverb
effect.
Diffusion 0...127
Determines the consistency of different room materials.
Lower settings produce a cold strong reflection like a
