Vowel

This effect filters the input to match a human voice singing a certain vowel sound. Human singing voice sounds are easily achieved with a source of a saw wave with a little vibrato.

Introduced in v2.10

Options

amp:

The amplitude of the sound. Typically a value between 0 and 1. Higher amplitudes may be used, but won’t make the sound louder, they will just reduce the quality of all the sounds currently being played (due to compression.)

Default: 1
Must be zero or greater
May be changed whilst playing
Has slide options to shape changes

pre_amp:

Amplification applied to the input signal immediately before it is passed to the FX.

Default: 1
Must be zero or greater
May be changed whilst playing
Has slide options to shape changes

vowel_sound:

1,2,3,4,5 => A,E,I,O,U

Default: 1
Must be one of the following values: [1, 2, 3, 4, 5]
May be changed whilst playing

voice:

0,1,2,3,4 => Soprano,Alto,Counter Tenor, Tenor, Bass

Default: 0
Must be one of the following values: [0, 1, 2, 3, 4]
May be changed whilst playing

Slide Options

Any parameter that is slidable has three additional options named _slide, _slide_curve, and _slide_shape. For example, 'amp' is slidable, so you can also set amp_slide, amp_slide_curve, and amp_slide_shape with the following effects:

_slide:

Amount of time (in beats) for the parameter value to change. A long parameter_slide value means that the parameter takes a long time to slide from the previous value to the new value. A parameter_slide of 0 means that the parameter instantly changes to the new value.

Default: 0

_slide_shape:

Shape of curve. 0: step, 1: linear, 3: sine, 4: welch, 5: custom (use *_slide_curve: opt e.g. amp_slide_curve:), 6: squared, 7: cubed.

Default: 5

_slide_curve:

Shape of the slide curve (only honoured if slide shape is 5). 0 means linear and positive and negative numbers curve the segment up and down respectively.

Default: 0
