Modulations
The modulation options can be very important for the emulation of acoustic
instruments. As a simple example, the introduction of vibrato into a trumpet sound
over time.
Many “classic” synthesizer sounds also rely as much on modulation as they do on the
basic sound source components—the VCO, VCF, and VCA.
Here’s a number of quick modulation tips …
• Let’s say you want to modulate the timbre of Object 2, with the LFO, for example. To
do so, click on the LFO 1 or 2 Tab, press the 1 or 2 button, select the desired Source/
Target and value. That’s it!
• To control any modulation with an external controller, such as your keyboard’s
modulation wheel, set the desired “Via” parameter to CtrlA or CtrlB respectively. By
default, the Mod Wheel is set to CtrlA.
• The “Bouncing” damp Type available to Object 3 affects the sound in a very
interesting way, but it cannot be run synchronously with the song tempo. To create a
similar effect to the “Bouncing” Object—but in-sync, you could use a “Disturb” object
Type, and move it by modulating its vertical position (Timbre) with an LFO.
“Breath” control is available to all users of Sculpture, even if you don’t own a breath
controller. To do so, record breath controller modulations into the recordable envelopes
(using a mod wheel or other controller), and then reassign the recorded modulation
path (use the CtrlEnv 1 and/or 2 parameters) with each NoteOn.
