• Pitch pop-up menu and field: Choose a criteria that snaps all pitches to the chosen
value.
• One Note: All pitches are snapped to a single pitch.
• Octaves: All pitches are snapped to the nearest octave.
• Fifths: All pitches are snapped to the nearest fifth.
• Octaves&Fifths: All pitches are snapped to the nearest octave or fifth.
• Chromatic: All pitches are corrected to a chromatic scale.
MainStage Alchemy formant filter controls
Source components are shown only in advanced view. Click the Advanced button to switch
to advanced view, then click the A/B/C/D button to select the source you want to edit.
The parameters in this section are shown when the Formant button is active in an additive
or spectral source subpage.
When audio is imported into the additive or spectral engines with the Formant option
enabled, the signal is analyzed and resonances in the original signal are extracted and
converted into a formant filter shape. See MainStage Alchemy Import browser.
The formant filter scales the amplitude of additive partials or spectral bins over time to
recreate the characteristic resonances of the instrument, rather than processing the audio
signal like a conventional filter.
Formant filter analyzed parameters
The analyzed controls work only if you enable the Formant button in the Import browser
when importing your audio files. This more detailed analysis attempts to determine the
resonant frequencies of the source audio data.
• On/off button: Enable or disable the analyzed formant section.
• Shift knob: Shift the formant filter up or down in semitones. Higher values can make
sounds seem brighter or thinner. Lower values can create a darker, thicker character.
• KTrack knob: Determine how the formant filter tracks notes on the keyboard. At 100%,
filter resonances shift up or down in pitch with the note. Set to lower values to reduce
key tracking which may make some sounds playable over a wider keyboard range.
