Editing VAST Programs With KVA Oscillators
The Forte SE 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 SE’s internal processing power and
complex signal routing capabilities. Though the Forte SE 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
Minimal Settings for 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:
1. EditProg:KEYMAP Page: Set the Keymap parameter to 999 Silence.
2. EditProg:AMPENV Page: Set the Envelope mode to User, and adjust the amplitude
envelope to your liking (see
The Amplitude Envelope (AMPENV) Page on page 7-48
3. EditProg:ALG Page: Pick an Algorithm and set an Oscillator (see
).
Further basic VAST settings that you will likely want to adjust are:
• Monophonic On/Off (see
• Level Velocity Tracking (see
The DSP Control (DSPCTL) Page on page 7-38
)
Read the
section below to learn about how to set each type of
oscillator. After doing this, you can experiment with making KVA programs by following
the above settings, and then setting and listening to each type of oscillator. Once you
understand how to do this, read on to the
Advanced Use Of KVA Oscillators on page 7-75
(see below) to learn how to make your KVA patches more expressive through the use of DSP
modulation.
Pitch Settings for KVA Oscillators
Each oscillator (except for noise functions) has its own pitch parameters, and is unaffected by
pitch settings that would normally affect keymaps (such as those on the Keymap page). On a
program layer, the coarse pitch parameter for the oscillator in use can be found on both the
DSPCTL and DSPMOD pages, in the parameters list below the standard Pitch parameter
