Setting Sculpture’s Glide (Portamento) Time
The Glide parameter controls the portamento time. This is the amount of time it takes
for the pitch of one played note to travel to the pitch of another played note.
The Glide parameter behavior depends on the chosen keyboard mode.
• If the keyboard mode is set to Poly or Mono, and Glide is set to a value other than 0,
portamento is active.
• If Legato is chosen, and Glide is set to a value other than 0, you need to play legato
(press a new key while holding the old one) to activate portamento. If you don’t play
in a legato style, portamento won’t work. This behavior is also known as fingered
portamento.
Using Sculpture’s Amplitude Envelope Parameters
The parameters discussed in this section apply on a per-voice basis. This is a straightforward
ADSR envelope that scales the pickup signals before passing them on to the Waveshaper
and filter. The positioning of the amplitude envelope at this point in the signal path
produces more natural sounding results because you can control signal levels before
sending them to the Waveshaper (if used). The Waveshaper can have a significant impact
on the spectral content of the sound, which can lead to synthetic sounding results.
• Attack—Soft and Hard slider(s): Divided into two halves. The lower slider half (Soft)
determines the attack time when the incoming MIDI note is played at maximum velocity.
The upper slider half (Hard) determines the attack time when the incoming MIDI note
is played at minimum velocity. You can adjust both slider halves simultaneously by
dragging in the space between them.
Important: The attack time parameters of the amplitude envelope have a major impact
on the way a single note is retriggered. When both Attack Soft and Hard are set to a
value of 0, the vibrating string is retriggered. If either of these parameters is set to a
value above 0, a new note will be triggered. Sonically, the retriggering of a vibrating
string will result in different harmonics being heard during the attack phase.
• Decay slider: Defines the decay time. The decay time is the amount of time that it takes
for the signal to fall to the sustain level, following the initial strike/attack time.
