Use Sculpture’s Waveshaper
The Waveshaper imposes a nonlinear shaping curve on each voice of the signal coming from the
pickups and amplitude envelope. This reshaped signal is then passed on to the lter. This process
is quite similar to the waveshaping of oscillators in synthesizers such as Korg’s O1/W.
Waveshaper parameters
•
Waveshaper On/O button: Turns the Waveshaper on or o.
•
Type pop-up menu: Select one of four waveshaping curves. See the table.
•
Input Scale knob (morphable): Rotate to cut or boost the input signal, prior to processing
by the Waveshaper. Positive values result in a richer harmonic spectrum. Any level increase
introduced by this parameter is automatically compensated for by the Waveshaper.
Note: Given its impact on the harmonic spectrum, Input Scale should be viewed and used as
a timbral control, rather than a level control. Also note that extreme Input Scale values can
introduce processing noise at the Waveshaper output.
•
Variation knob (morphable): Rotate to change. Impact is dependent on the selected
Waveshaper curve. See the table.
Type Variation controls Value of 0.0 Negative values Positive values
VariDrive Wet/dry ratio Provides shaped
signal only.
Reduces shaped
signal and adds dry
signal.
Raises shaped
signal and adds
phase-inverted
dry signal, making
sound sharper.
