Sound Generation
35
the lowest octave of a piano, which sounds quite metallic. This is because
the physical qualities of those heavy-gauge piano strings, found in the
lowest octave, are quite similar to those of metal tines or plates.
▶
Press AP Tune (Comb Filter) until AP Reson is highlighted in the display.
▶
Sweep the Encoder across the entire range while playing some notes. Then
dial in approx. [ 50.0 % ].
ߊ The resonance parameter of the allpass filter adds a lot of sound-sculpt-
ing potential. Explore the interaction between AP Tune and AP Reson
carefully. They produce approximations of sonic characteristics that are
similar to metal tines, plates, and more.
▶
Reset all AP Tune parameters to their default values.
Varying the Exciter Settings (Oscillator A)
Even when the Oscillator signal is not audible, its qualities are crucial to the
resulting sound. Envelope shape, pitch, and overtone structure of the exciter have a
profound impact on the resonator (Comb Filter).
Envelope shape:
▶
Press Sustain (Envelope A).
▶
Set the Encoder to approx. [ 30.0 % ]
▶
Press Attack (Envelope A).
▶
Set the Encoder to [ 100 ms ]
▶
Press Decay 2 (Envelope A).
▶
Set the value to [ 100 ms ] (default).
ߊ Oscillator A – the exciter of the Comb Filter – will no longer provide a
short ping but a steady tone.
▶
Press Pitch (Oscillator A).
▶
Sweep the Encoder slowly across the entire range and play notes. Then dial
in [ 48.00 st ]. Enjoy...
ߊ Depending on Oscillator 1 Pitch, you will find interesting resonating
frequencies as well as frequency cancellations. The sonic character is
sometimes reminiscent of (over)blown reeds or bowed strings.
