VAST and KB3 Programs

VAST and KB3 Programs
It is important to understand the dierence between VAST programs and KB3 programs.
VAST programs contain up to 32 layers, each of which contains a keymap or KVA oscillator.
Keymaps consists of a number of samples assigned to a particular keyboard range. KVA
oscillators use powerful DSP (digital signal processors) to generate a range of simple and
complex waveforms. See Editing VAST Programs With KVA Oscillators on page 7-72) for
more details. See VAST Program Structure below for details on VAST programs.
KB3 programs use a much dierent architecture. ere are no layers or algorithms, just
a set of oscillators (designed to emulate the tonewheels in a Hammond Organ) that start
running as soon as you select a KB3 program. See KB3 Program Structure for details on KB3
programs.
VAST Program Structure
"Figure 7-1 VAST Program Structure" on page 7-5 depicts the hierarchy of a VAST
program, from individual samples all the way up to Multis, which can contain up to 8
programs.
Every VAST program contains at least one layer. A layer consists of a keymap and an
algorithm for processing the samples contained in the keymap. Each sample is a separate
digital recording of some kind of sound: musical, vocal, industrial, any sound at all.
Individual samples are assigned to specic key ranges (from A 2 to D 3, for example), and
are also assigned to be triggered at specic attack velocities. ese assignments constitute the
keymap.
When you trigger a note, the Forte SE looks to the keymap of each layer of the currently
active VAST program(s) to determine which samples to play. e sound engine then fetches
the requested samples and generates a digital signal representing the sound of the samples.
is signal rst passes through the DSP functions that make up the algorithm. It then passes
through the Forte SE’s eects processor, and nally appears—with some level of eects
applied to it—at one or more of the audio outputs.
e layer is the VAST program’s basic unit of polyphony, that is, each layer constitutes one
of the 128 voice channels the Forte SE can activate at any time. If you have a program that
consists of two layers covering the note range from A 0 to C 8, each key you strike triggers
two voice channels.
Note: One exception to this structure is when using a KVA oscillator, the sound source
for that layer is not derived from a keymap, but is generated at the algorithm stage
(though keymap information is still used to set key range and maximum amplitude).
After this, the structure is the same as described above. See Editing VAST Programs
With KVA Oscillators on page 7-72 for more details.
