NOISE

A simple noise generator. Use the Noise parameter to control the noise initial amplitude.
SW + SHP (Sawtooth + Shaper)
This oscillator is capable of basic FM Synthesis. Its distinctive parameter is Pch Coar. This
oscillator must come after the sound source in an algorithm (either keymap or oscillator)
in order to hear the effect of Pch Coar, which can radically change whatever the oscillator
receives as an input. Works well placed after a Sine source.
SINE+ [Aliased (not recommended)]
Same as 2 block version, but without the Sine+Am parameter.
SAW+ [Aliased (not recommended)]
A saw oscillator that can add an input signal to its output.
NOISE+ [Aliased (not recommended)]
A noise oscillator that can add an input signal to its output.
2 Block:
SINE+
A sine oscillator that can add an input signal to its output. The Sin+ Pch and Sine+ Am
parameters affect the pitch and amplitude of the sine waveform without affecting the pitch of
the input source.

RES NOISE

A noise generator combined with a low pass filter with resonance control. Use the Noiz Frq
parameter to control the cut off frequency of the filter. Use the Noiz Q parameter to control
the amplitude of the resonance (a boost or cut at the cut off frequency). One technique for
use of this function is to set a high value for Noiz Q (so that you hear a the resonance create
a tone,) and then on the DSP CTL page set C4 as an initial frequency for Noiz Frq, and
set Keytrk to 100ct/key on the Noiz Frq sub page. Doing this causes the noise resonance
frequency to match the note of the key played.

SHAPED SAW

The Shaped Saw oscillator is a sawtooth oscillator with the ability to morph its output shape
between sawtooth and sine wave (without crossfading). This oscillator's distinctive parameter
is Shape, which controls the morphing. With Shape set to 0, the oscillator produces a pure
sawtooth wave. With Shape set to 127, the oscillator produces a pure sine wave. Values in
between morph between the two wave shapes.
