Versatile wobble FX. Will repeatedly modulate a range of filters (rlpf, rhpf) between two cutoff values using a range of control wave forms (saw, pulse, tri, sine). You may alter the phase duration of the wobble, and the resonance of the filter. Combines well with the dsaw synth for crazy dub wobbles. Cutoff value is at cutoff_min at the start of phase

Introduced in v2.0

 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, it 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 parameters to shape changes

 mix:

The amount (percentage) of FX present in the resulting sound represented as a value between 0 and 1. For example, a mix of 0 means that only the original sound is heard, a mix of 1 means that only the FX is heard (typically the default) and a mix of 0.5 means that half the original and half of the FX is heard.
Default: 1
must be a value between 0 and 1 inclusively
May be changed whilst playing
Has slide parameters 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 parameters to shape changes
Scaled with current BPM value

 phase:

The phase duration (in seconds) for filter modulation cycles
Default: 0.5
must be greater than zero
May be changed whilst playing
Has slide parameters to shape changes
Scaled with current BPM value

 cutoff_min:

Minimum (MIDI) note filter will move to whilst wobbling. Choose a lower note for a higher range of movement. Full range of movement is the distance between cutoff_max and cutoff_min
Default: 60
must be zero or greater,must be a value less than 130
May be changed whilst playing
Has slide parameters to shape changes

 cutoff_max:

Maximum (MIDI) note filter will move to whilst wobbling. Choose a higher note for a higher range of movement. Full range of movement is the distance between cutoff_max and cutoff_min
Default: 120
must be zero or greater,must be a value less than 130
May be changed whilst playing
Has slide parameters to shape changes

 res:

Filter resonance. Large amounts of resonance (a res: near 0) can create a whistling sound around the cutoff frequency. Smaller values produce more resonance.
Default: 0.2
must be greater than zero
May be changed whilst playing
Has slide parameters to shape changes

 phase_offset:

Initial modulation phase offset (a value between 0 and 1).
Default: 0
must be a value between 0 and 1 inclusively
Can not be changed once set

 wave:

Wave shape of wobble. Use 0 for saw wave, 1 for pulse, 2 for triangle wave and 3 for a sine wave.
Default: 0
must be one of the following values: [0, 1, 2, 3]
May be changed whilst playing

 pulse_width:

Only valid if wave is type pulse.
Default: 0.5
must be zero or greater
May be changed whilst playing
Has slide parameters to shape changes

 filter:

Filter used for wobble effect. Use 0 for a resonant low pass filter or 1 for a rsonant high pass filter
Default: 0
must be one of the following values: [0, 1]
May be changed whilst playing

Slide Parameters

Any parameter that is slidable has three additional parameters 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 seconds) 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 curvature param), 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
