Using 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 filter. This is quite similar to the waveshaping of oscillators in synthesizers such as Korg’s O1/W.
- Waveshaper On/Off button: Enables or disables the Waveshaper.
- Type menu: Choose one of four waveshaping curves. See table below.
- Input Scale knob (morphable): Attenuates or amplifies the input signal, prior to processing by the Waveshaper. Positive values result in a richer harmonic spectrum. Any level increase introduced by the 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): Impact is dependent on the type of Waveshaper selected. See table below.
Type | Variation controls | Value of 0.0 | Negative values | Positive values |
|---|---|---|---|---|
VariDrive | Wet/dry ratio | Provides shaped signal only. | Reduce shaped signal and add dry signal. | Raise shaped signal and add phase-inverted dry signal, making sound sharper. |
| Bias—which alters the symmetry of the shaping curve. | Results in symmetrical shaping. | Alter symmetry. | Alter symmetry. |
