Chapter 24 Sculpture 361
Voices
When Keyboard Mode is set to Poly, this parameter limits the number of simultaneously
sounding voices to the set value. A value of 16 voices is the maximum polyphony of
Sculpture.
Keyboard Mode
Here, you can select between the Mono, Legato or Poly Keyboard Modes.
You can switch between mono and poly modes by clicking on the Poly and Mono
buttons. The Portamento, the duration of which is set by the Glide Time parameter,
affects legato performances. As long as you don’t release the key of the previously
struck note before pressing a new key, you’ll hear the glide or portamento. If you
release every note before striking another key (portato or even staccato style), the glide
effect will not be audible.
When the Legato button is activated, a further side-effect occurs. The Amplitude
Envelope is not retriggered—the sound is sustained and the Attack phase of newly
played notes is not retriggered. These behaviors are sometimes referred to as Single
Trigger and Multi Trigger modes.
All modes simply retrigger a (potentially sounding) voice with the same pitch, instead
of allocating a new one. As such, multiple triggering of a given note results in slight
timbral variations, depending on the current “state” of the model at note-on time.
If Sculpture’s String is still vibrating for a specific note, retriggering that same note will
interact with the ongoing vibration, or current “state” of the string.
Important: A “true” retrigger of the vibrating string will only happen if both Attack
sliders of the Amplitude Envelope are set to zero. If either slider is set to any other value,
a new voice will be allocated with each retriggered note.
