Note Slider Settings

Figure 4.39. Note Slider Settings

On this dialog you can adjust the appearance and behavior of the Overtone Sliders (which are also called Note Sliders). Most of those settings can also be found on the toolbar.

Fixate note sliders on screen

If this setting is active, the note sliders are fixated on the screen and will stay in the same position regardless of how the time range of the Analyzer View is changed. In VoceVista Video Free Edition the sliders are always fixated on the screen. When the sliders are not fixated on the screen, each slider belongs to a specific time range of the recording, like the notes in a piece of music. This allows to represent an entire recording as a melody comprised of musical notes, which can also be exported as a MIDI file.

Number of Overtone Sliders

This is the number of distinct sliders shown. Each slider can have a separate fundamental frequency. The number of sliders can only be changed through this control if the sliders are fixated on the screen. Otherwise, sliders can be added and deleted through the commands ToolsInsert note slider at selection and ToolsDelete note selected sliders.

Note Slider Labels

Show note name

Show the name of a slider’s note, such as A3+12ct. The second part of the name shows the difference in cent between the exact pitch of the slider, and the named note on the piano.

Show frequency

Show the pitch of a slider’s frequency, such as 220 Hz.

Hide middle labels

If this option is activated, the note name and frequency will only be shown for the fundamental, and for the highest displayed overtone, and the lowest displayed undertone of each slider.


This option makes the sliders transparent so that the spectrogram underneath can still be seen. This can make it easier to position sliders accurately. The amount of transparency requires some experimentation for each situation. It can be adjusted here, but the transparency can also be adjusted through a slider on the status bar.

Undertone octaves only

This option will hide all undertones that are not an octave of the fundamental. This can be useful when constructing scales, where tones are used across many octaves.

Play top labels

Checking this option will cause the highest visible overtone of each slider to be played together with the fundamental, when the fundamental is played by clicking on it. This can be used to play overtone melodies together with the fundamental.


When moving a slider along the frequency axis while this option is enabled, the slider will snap to the nearest piano note or spectral peak. This behavior can be reversed when the ALT key is pressed while moving a slider (for more keyboard modifiers, including the possibility to snap to other sliders, refer to Table 4.2, “Overtone Slider Mouse Commands”).

no snapping

The sliders can be moved freely.

snap to nearest musical note

The slider will snap to the frequency that represents the nearest note on the piano.

snap to nearest peak in spectrum

The slider will snap to the nearest maximum in the spectrum. This allows to accurately measure the loudest frequencies in a recording.


highlight note borders

Checking this option will draw the note borders with high contrast, which can be useful when editing note sliders.
