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 Forte SE 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.
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.
