Editing VAST Programs With KVA Oscillators

Editing VAST Programs With KVA Oscillators
The K2700 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 K2700's internal processing power and
complex signal routing capabilities. Though the K2700 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. Program Edit Keymap Page: Set the Keymap parameter to 999 Silence.
2. Program Edit Amp Envelope Page: Set the Envelope mode to User, and adjust the
amplitude envelope to your liking (see
3-65).
3. Program Edit Wiring Alg Page: Pick an Algorithm and set an Oscillator (see
Oscillator Type on page
Further basic VAST settings that you will likely want to adjust are:
• Monophonic On/Off (see
• Level Velocity Tracking (see

above settings, and then setting and listening to each type of oscillator. Once you understand
how to do this, see
