Oscillator type list

WAVE FORM

(Wave form)

This oscillator type provides two oscillators whose waveform you can modify continuously. OSC EDIT2 adjusts the pitch of oscillator 2 (i.e., the pitch difference relative to oscillator 1), letting you create detuned sounds or octave-doubled sounds.

WAVE ..........................................

Saw, Pulse, Tri, Sin

Selects the basic waveform for the wave form oscillator. Oscillator 1 and oscillator 2 will have the same waveform.

Saw: A sawtooth wave is the most widely used waveform on an analog synthesizer. It is suitable for creating a wide range of sounds including synth basses and synth leads. Adjusting the OSC EDIT1 value will modify the waveform as shown in the illustration below. At a setting of 0 the waveform will be a standard sawtooth wave, and at a setting of 127 it will be a square wave.

Pulse: A pulse waveform produces a tone that is often heard in electronic music. OSC EDIT1 adjusts the pulse width. At a setting of 0 the waveform will be a basic square wave, and as you increase the setting the pulse width will decrease, producing a more clavi-like tone. At a setting of 127 the pulse width will be 0, meaning that there will be no sound. By selecting a triangle wave as the modulation type and applying modulation to OSC EDIT 1, you can produce a PWM (Pulse Width Modu- lation) effect, giving depth to the sound.

Tri: A triangle wave has a stronger fundamental and fewer overtones than a sawtooth wave or pulse wave. It is suitable for mellow bass or arpeggiated sounds. Adjusting the OSC EDIT1 value will modify the waveform as shown in the illustration below. At a setting of 0 the waveform will be a basic triangle wave, and at a setting of 127 it will be a triangle wave of one octave and a fifth higher.

Sin: A sine wave contains only the fundamental with no overtones, producing an extremely mild tone for which it is difficult to hear the effect of subsequent filtering.

Adjusting the OSC EDIT1 value will modify the waveform as shown in the illustration below, changing the overtones that are produced. At a setting of 0 the waveform will be a basic sine wave.

OSC EDIT1: Waveform ..................................

0...127

This continuously modifies the shape of the wave- form. The waveform shape will change in the same way for oscillator 1 and oscillator 2.

OSC EDIT2: OSC2Ptch

..............................

-63...+63

This adjusts the pitch of oscillator 2. A value of ±63 creates a pitch difference of ±2 octaves, and a value of 47 creates a pitch difference of ±1 octave. For values in the region of 0, only the sound of oscillator 1 will be output.

DUAL OSC

(Dual oscillator)

This oscillator type provides two oscillators that output basic waveforms. You can choose the combination of waveforms for the two oscillators.

WAVE ......................................................................

 

twenty different combinations of Osc1 (Saw, Squ, Tri,

Sin) + Osc2 (Saw, Squ, Tri, Sin, Ns [=Noise])

 

OSC EDIT1: OSCBlnce ...................................

0...127

Adjusts the volume balance of oscillator 1 and oscillator

2.A setting of 0 outputs only oscillator 1, and a setting of

127outputs only oscillator 2.

OSC EDIT2: OSC2Ptch ..............................

-63...+63

Adjusts the pitch of oscillator 2. A value of ±63 creates a pitch difference of ±2 octaves, and a value of 47 creates a pitch difference of ±1 octave. With a value of 0, the pitch

will be the same as the pitch of oscillator 1.
