Tracking oscillator parameters
• FMRatio field: Set the ratio between Oscillators1 and 2, which defines the basic
character of the sound. Even-numbered values or their multiples produce harmonic
sounds, whereas odd-numbered values or their multiples produce inharmonic, metallic
sounds.
• An FMRatio of 1.000 produces results resembling a sawtooth waveform.
• An FMRatio of 2.000 produces results resembling a square wave with a pulse width
of 50%.
• An FMRatio of 3.000 produces results resembling a square wave with a pulse width
of 33%.
• 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.
MainStage 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.
