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
PC3A 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 is possible to create with the user
amplitude
envelope, and they are useful when trying to mimic specific instrument amplitude envelopes.
When using this technique, remember that
the maximum amplitude of each key is set by the
current keymap. You can still control the overall parameters of a natural envelope by using the
ENVCTL page. See the programs
213 Perc>Morph>Bass
&
315
ElectroPercSynth
for examples
of KVA layers that use this technique. Each program uses percussion keymaps with natural
envelopes to produce a fast, percussive attack. Also note that when using a KVA oscillator and a
keymap other than
999 Silence,
the layer will use the name of the keymap in the info box on the
main Program page, even though it is not the true sound source of the layer.
Note:
The samples from a keymap are not heard when using an oscillator, unless an algorithm is used to
route the keymap signal around the oscillator and into a MIX function block, or unless it is an oscillator
that processes its audio input.
