• FM Int knob: Determine the intensity of modulation. Higher values result in a more
complex waveform with more overtones.
• At a value of 0, the FM tone generator is disabled and a sawtooth wave is generated.
• At values above 0, the FM tone generator is activated. Higher values result in a more
complex and brighter sound.
• Coarse Tune field: Set the pitch offset of the oscillator in semitones.
• Fine Tune field: Adjust the tuning in hertz.
Logic Pro EVOC 20 TrackOscillator oscillator pitch controls
The tracking oscillator pitch parameters control the automatic pitch correction feature of
the tracking oscillator. They can be used to constrain the pitch of the tracking oscillator to
a scale or chord. This allows subtle or strong pitch corrections and can be used creatively
on unpitched material with high harmonic content, such as cymbals and high-hats.
Tracking oscillator pitch parameters
• Pitch Quantize Strength slider: Determine how pronounced the automatic pitch
correction is.
• Pitch Quantize Glide slider: Set the amount of time pitch correction takes, allowing
sliding transitions to quantized pitches.
• Root/Scale keyboard: Click notes to define the pitch or pitches that the tracking
oscillator is quantized to.
• Root/Scale pop-up menu: Click below Scale to choose the scale that the tracking
oscillator is quantized to.
Note: There are two discrete fields available for this parameter: Root and Scale. The
Root (key) can be changed independently of the scale chosen in the pop-up menu.
• Max Track field: Set the highest frequency. All frequencies above this threshold are
cut, making pitch detection more robust. If pitch detection produces unstable results,
reduce this parameter to the lowest possible setting that allows all appropriate input
signals to be heard or processed.
Choose a root or scale in EVOC 20 TrackOscillator
1. In Logic Pro, click the green value field under Scale to open the pop-up menu.
2. Choose the scale or chord you want to use as the basis for pitch correction.
Note: You can also set the root key of the chosen scale or chord by vertically dragging the
Root (key) field, or by double-clicking the root note and entering a root key between C and
B. The Root parameter is not available when the Root/Scale value is set to “chromatic”
or “user.”
