Editing VAST Programs With KVA Oscillators
4 Block:
SYNC SAW
Sync Saw consists of two saw waves, one that you hear (the slave) and one that controls the
slave (the master). This oscillator's distinctive parameter is SyncOff, which controls the offset
of the slave and master waves. With SyncOff set to 0, the master has no effect on the slave.
When an offset is set, the slave restarts its wave cycle every time the master wave completes
a cycle. Offsets cause the slave to restart its cycle in the middle of normal sawtooth cycles,
which causes the slave's waveform shape and sound to be altered.
SUPER SAW
The Super Saw oscillator consists of two saw waves. This oscillator's distinctive parameter is
Detune, which has settings from 0-50 cents, allowing you to detune both of the saw waves
by up to 50 cents away from the root pitch of the key played. Detune affects both saw waves,
one is detuned above the original root pitch, and the other is detuned below the original root
pitch.
TRIPLE SAW
The Triple Saw oscillator consists of three saw waves. This oscillator's distinctive parameter
is Detune, which has settings from 0-50 cents, allowing you to detune two of the saw waves
by up to 50 cents away from the root pitch of the key played. Detune affects two of the
saw waves, one is detuned above the original root pitch, and the other is detuned below the
original root pitch. The third saw wave always plays the root pitch and is not affected by
Detune.

Use Of Keymaps and Natural Amplitude Envelopes With KVA Oscillators:
Keymaps are important in layers using KVA oscillators, even though their samples are
not usually heard in these layers (see the note below for exceptions). Keymap selection
is important because the maximum amplitude set for each key in the keymap is applied
to the oscillator. For most uses of KVA oscillators, users will want to use the 999 Silence
keymap because each key in the keymap is set to the same maximum amplitude, unlike
many instrument keymaps. The 999 Silence keymap ensures uniform amplitude behavior
of an oscillator, and with the amplitude envelope set to user mode, users can easily shape all
aspects of an oscillator's amplitude. The K2700 also has the ability to apply natural amplitude
envelopes to oscillators. With an amplitude envelope set to natural mode, each oscillator
note takes on the amplitude qualities of each sample in a keymap (with each note relative
to sample key placement). Each sample in a keymap has a natural envelope that was created
during it's original development process. Natural envelopes have much more detail than what
