486 Chapter 28 Sculpture
 Two control envelopes can either be used as standard envelopes or as MIDI
controlled modulators—with the ability to record, polyphonically play back (on a
per-voice basis), and modify incoming MIDI controller movements.
All modulation assignments take place within the generators.
First order modulations are where the modulation generator modulates core synthesis
parameters. Second order modulations are where one modulation generator modulates
the parameters of the other modulation generator. These include: LFO Rate
Modulation, VariMod, Morph Envelope Modulation, and A Time Velosens.
Each modulation generator allows you to select one (or in most cases, two) of the core
synthesis parameters as a modulation target. The same target can be selected for all
modulators, if desired.
Modules such as the LFOs and control envelopes also offer via modulations (a freely
modulatable amount/intensity—the scaling factor—of the modulation source output
level). These are sidechain modulations.
Some modulation generator parameters—for example LFO rates, can be modulated by
selecting the desired modulation source and amount.
To access the desired modulation generator, click on the corresponding button in this
section of the Sculpture interface. Once a modulation source has been activated, the
corresponding button label will be lit.
LFO 1 and 2
The two full-featured LFOs offer several possibilities that go beyond the Vibrato LFO
and jitter generators described below.
Waveform
This menu allows you to choose the waveform used for LFO modulation. Options
are: Sine, Triangle, Sawtooth, Rectangle Unipolar, Rectangle Bipolar, Sample&Hold,
Sample&Hold with Lag, Filtered Noise.
 The triangular wave is well suited for vibrato effects.
