Sound Generation

• B – the first filter section works as a highpass, the second as a lowpass. Low and
high frequencies are both attenuated and a frequency band with variable width
(“Spread”) passes the S.V. Filter. Particularly at higher Resonance settings, vowel/
vocal-like sounds can be achieved.
• FM provides a Cuto modulation by the Oscillator/Shaper signals A and B. Very
good for aggressive and distorted sounds.
Check out the parameters mentioned above and keep in mind that they all interact
with each other in some way. Use the Default button to reset a parameter value.
Envelope / Key Tracking modulation of Cuto and Resonance:
▶
Press Cuto (State Variable Filter) until Env C is highlighted in the display .
▶
Set the Encoder to [ 70.00 st ].
ߊ You will hear the sound becoming increasingly dull over time since the
Cuto is modulated by Envelope C.
Vary the settings of Envelope C parameters and the modulation depth
(“Env C”). For more dramatic filter “sweeps” set the Resonance of the S.V.
Filter to higher values.
▶
Press Cuto (State Variable Filter) until Key Trk is highlighted in the display.
▶
Sweep the Encoder across the entire range and dial in [ 50.0 % ].
ߊ When set to 0.0 %, Cuto has the same value across the entire keyboard
range. When reducing the Key Tracking value, the Cuto value will
increase in higher keyboard ranges and the sound grows brighter – an
eect you can find with many acoustic instruments.
Please check Env C / Key Trk modulation of the Resonance as well.
Changing the Filter Characteristics:
ߊ The S.V. Filter is a four-pole filter composed of two two-pole filters.
The Spread parameter determines the interval between the two cuto
frequencies of these two parts.
▶
Set the Resonance to [ 80 % ].
▶
Press Spread (State Variable Filter).
▶
By default, Spread is set to 12 semitones. Try settings between 0 and 60
semitones and also vary the Cuto.
ߊ When reducing the Spread value, the two peaks will emphasize each
other and the result will be a very intensely resonating, “peaking” sound.
