Favorites 6: New Parameter
When assigning a physical controller or CC number to a VAST source field, a Parameter
is automatically added to the Parameters Page (unless the physical controller/MIDI CC is
already being used by an existing Parameter on the Parameters Page). In other cases it may
be desirable to manually create a new Parameter. Press the Favorites 6 button to create a
new Parameter. At the prompt, choose a Destination and then name the Parameter. The
Parameter Destination is the default MIDI CC number that the Parameter will send to the
Program. The Destination also becomes the default Control for the Parameter. Once the
parameter is created, you can change its Control on the Parameters Page.
Favorites 9: Edit Description
Press the Favorites 9 button to enter description editor, where you can edit the program
description text. Program descriptions appear on the Parameters page at the bottom of the
Parameters list. The program description can be useful for providing extra information about
a program, keeping notes about parameter assignments, or adding your name when sharing
programs

Editing VAST Programs With KVA Oscillators
The Forte uses KVA oscillators as another way to generate sounds in VAST programs.
Unlike keymaps, which play samples stored in ROM, KVA oscillators create DSP-
generated waveforms every time they are triggered. The KVA oscillators can create a range
of waveforms, from high quality simple waveforms familiar to users of classic analog synths,
to complex waveforms which take advantage of the Forte’s internal processing power and
complex signal routing capabilities. Though the Forte does have keymaps containing
samples of basic synth waveforms, the use of KVA oscillators provides users with better
portamento, more modulation options, higher sound quality, and other advantages which
will be explained in this section. Learning to use KVA oscillators instead of keymaps (where
appropriate) is simple and will increase the versatility of your VAST editing capabilities.
VAST programs using layers with KVA oscillators can also be combined with other layers
using keymaps.
Basic Use of KVA Oscillators

These are the minimal settings that a KVA layer needs in order to function in the style of a
classic analog synth:
