The following parameters are common to each oscillator:

Oscillator Tuning Parameters

OCTAVE

• Range is -2 to +2 octaves.

SEMITONE

• Range is -12 to +12 semitones.

FINE

• Range is -50 to +50 cents. 100 cents = 1 semitone, so this parameter lets you

detune the oscillator by as much as a quarter-tone either way. Great for thicken-

ing and doubling the sound.

BEAT

• Range is 0 to 100%. This is a musical fine detune control. When the two oscilla-

tors are detuned by a fixed amount with the FINE control, you will discover that

there is a subtle ‘beating’ effect between them. This beating will be faster for

higher pitched notes and slower for lower pitched notes, and this may not be

desirable. The BEAT control allows you to detune the oscillators so that the beat-

ing is constant for all notes played.

Oscillator Waveform Parameters

SAWTOOTH LEVEL ( )

• Range is 0 to 100 %. Adjusts the oscillator’s sawtooth wave output level.

TRIANGLE LEVEL ( )

• Range is 0 to 100 %. Adjusts the oscillator’s triangle wave output level.

PULSE LEVEL ( )

• Range is 0 to 100 %. Adjusts the oscillator’s pulse wave output level.

PULSE WIDTH

• Range is 0 to 100 %.The oscillator’s pulse wave width is adjustable, where 0%

results in a narrow pulse wave, 50% results in a square wave and 100% results in

a wide pulse wave.

PWM FREQUENCY

• Range is 0 to 100%. PWM stands for Pulse Width Modulation. Each oscillator

has a dedicated LFO to modulate or change its pulse width. This control sets the

speed (or frequency) of the PWM LFO.

PWM DEPTH

• Range is 0 to 100%. This control sets the amount (or depth) of the PWM applied

by the LFO.
