The LFO+ Page
7-44
Each function-parameter’s subpage contains the programmable parameters of the highlighted
function-parameter. By assigning control sources to modulate a function-parameter, you
can enable real-time control of your program’s sound and behavior. You can assign Src1 to
any control source, and can specify its maximum value with the Depth parameter. Src2 is
dierent—you can assign it to any control source, but can also assign a control source to its
maximum value with the DptCtl parameter. You can then specify the range of Src2’s depth
with the MinDepth and MaxDepth parameters.
Note: e Forte features an easy shortcut for quickly assigning any of the realtime
controllers (sliders, wheels, buttons, etc.) to a currently selected parameter (such as
the Src1 and Src2 parameters above). Simply hold the Enter button and move the
desired controller.
The LFO+ Page
is page provides access to a number of oscillators, envelopes, and functions used to build a
VAST program.
About LFOs
LFOs are low-frequency oscillators. LFOs are used to automate the modulation of a
parameter based on the shape and frequency of an audio waveform. You’ll use the LFO page
to dene the behavior of the two LFOs available to each layer. LFOs are periodic (repeating)
control sources. e basic elements are the rate, which denes how frequently the LFO
repeats, and shape, which denes the waveform of the modulation signal it generates.
