Dual mode oscillator parameters
Semi field: Adjust the tuning of oscillator2 in semitone steps.
Detune field: Fine-tune both oscillators in cents. One hundred cents equals one
semitone step.
Balance slider: Set the level balance between the two oscillator signals.
Logic Pro EVOC20 PolySynth oscillator FMmode
In FMmode, oscillator1 generates a sine wave. The Wave 1 parameter has no effect in this
mode.
FMmode oscillator parameters
Ratio coarse field: Drag to adjust the frequency ratio between oscillator2 and
oscillator1 in semitone steps.
Ratio fine field: Drag to adjust the frequency ratio between oscillator2 and oscillator1
in cents. One hundred cents equals one semitone step.
FMInt slider: Drag to determine the intensity of modulation. Higher values result in a
more complex waveform with more overtones.
Logic Pro EVOC20 PolySynth noise generator
The noise generator provides a further sound source that can be used alongside the two
oscillators.
Important: The noise generator in the oscillator section is independent of the noise
generator in the U/V detection area. For further information about voiced and unvoiced
signals, see Logic Pro EVOC20 PolySynth (U/V) detection.
