ADDITIVE OSC
The additive oscillator creates a waveform by adding three
oscillators. This is a good way to make organ or bell sounds.

Harmonics
WAVE ............................................ Saw, Squ, Tri, Sin
Selects the basic waveform.
OSC EDIT1: OSC2Harm ..................... 00.25...32.00
Specifies the pitch of oscillator 2 as a harmonic multiple
of oscillator 1.
OSC EDIT2: OSC3Harm ..................... 00.25...32.00
Specifies the pitch of oscillator 3 as a harmonic multiple
of oscillator 1.
COMB OSC
This oscillator type contains an internal comb filter, and modifies
a basic waveform by passing it through the comb filter to change
the tone. By using the LFO to modulate the frequency (OSC EDIT2)
of the comb filter, you can create the same result as a flanger
effect.
Level NoteNo. + Comb Pitch
Feedback
WAVE ................................. Saw, Squ, Tri, Sin, Noise
Selects the basic waveform of the oscillator.
OSC EDIT1: Feedback ................................... 0...127
Raises the amount of feedback returned to the comb fil-
ter. As the feedback amount increases, the comb filter ef-
fect will be applied, boosting the overtones at multiples
of the frequency specified by OSC EDIT2.
OSC EDIT2: CombPtch ................................... 0...127
Adjusts the frequency that will be the axis of the comb
filter. At a value of 0 this will be the basic pitch; a value of
31 is one octave higher, 63 is two octaves higher, 95 is three
octaves higher, and 127 is four octaves higher.

FORMANT OSC
The formant oscillator type can produce a sound reminiscent
of a human voice. By moving the formant width (OSC EDIT1)
you can change between different vowels.
Formant Width
Formant Shift
WAVE ........................................................ --- (none)
OSC EDIT1: Formant .....................................0...127
Controls the frequency difference between the two
formants. This produces a change similar to varying the
shape and size of your mouth when producing "vowel"
tones.
OSC EDIT2: Offset ..................................... -63...+63
Moves the formant frequency components upward or
downward in pitch.
NOISE OSC
The noise oscillator contains an internal noise generator and
filters, allowing you to create a variety of noise sounds. Since
the filters resonate to oscillation, you can also use this to cre-
ate pitched sounds.
Noise
Rate
Generator
WAVE ........................................................ --- (none)
OSC EDIT1: Rate ...........................................0...127
Adjusts the character of the source noise (the speed of the
random cycle). Raising this value will slow the timing at
which noise is generated.
OSC EDIT2: Color ..................................... -63...+63
Adjusts the mix balance between the LPF (Low Pass Fil-
ter) and HPF (High Pass Filter) that are placed after the
noise generator. With a value of -63 only the LPF is heard,
and with a value of +63 only the HPF is heard.
