Emulation of the classic Roland TB-303 Bass Line synthesiser. Overdrive the res (i.e. use very small values) for that classic late 80s acid sound.

Introduced in v2.0

 note:

Note to play. Either a MIDI number or a symbol representing a note. For example: 30, 52, :C, :C2, :Eb4, or :Ds3
Default: 52
must be zero or greater
May be changed whilst playing
Has slide parameters to shape changes

 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

 pan:

Position of sound in stereo. With headphones on, this means how much of the sound is in the left ear, and how much is in the right ear. With a value of -1, the soundis completely in the left ear, a value of 0 puts the sound equally in both ears and a value of 1 puts the sound in the right ear. Values in between -1 and 1 move the sound accordingly.
Default: 0
must be a value between -1 and 1 inclusively
May be changed whilst playing
Has slide parameters to shape changes

 attack:

Amount of time (in seconds) for sound to reach full amplitude (attack_level). A short attack (i.e. 0.01) makes the initial part of the sound very percussive like a sharp tap. A longer attack (i.e 1) fades the sound in gently. Full length of sound is attack + decay + sustain + release.
Default: 0
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 decay:

Amount of time (in seconds) for the sound to move from full amplitude (attack_level) to the sustain amplitude (sustain_level).
Default: 0
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 sustain:

Amount of time (in seconds) for sound to remain at sustain level amplitude. Longer sustain values result in longer sounds. Full length of sound is attack + decay + sustain + release.
Default: 0
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 release:

Amount of time (in seconds) for sound to move from sustain level amplitude to silent. A short release (i.e. 0.01) makes the final part of the sound very percussive (potentially resulting in a click). A longer release (i.e 1) fades the sound out gently. Full length of sound is attack + decay + sustain + release.
Default: 1
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 attack_level:

Amplitude level reached after attack phase and immediately before decay phase
Default: 1
must be zero or greater
Can not be changed once set

 sustain_level:

Amplitude level reached after decay phase and immediately before release phase.
Default: 1
must be zero or greater
Can not be changed once set

 env_curve:

Select the shape of the curve between levels in the envelope. 1=linear, 2=exponential, 3=sine, 4=welch, 6=squared, 7=cubed
Default: 2
must be one of the following values: [1, 2, 3, 4, 6, 7]
Can not be changed once set

 cutoff:

The maximum cutoff value as a MIDI note
Default: 120
must be a value less than or equal to 130
May be changed whilst playing
Has slide parameters to shape changes

 cutoff_min:

The minimum cutoff value.
Default: 30
must be a value less than or equal to 130
May be changed whilst playing
Has slide parameters to shape changes

 cutoff_attack:

Attack time for cutoff filter. Amount of time (in seconds) for sound to reach full cutoff value. Default value is set to match amp envelope's attack value.
Default: attack
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 cutoff_decay:

Decay time for cutoff filter. Amount of time (in seconds) for sound to reach full cutoff value. Default value is set to match amp envelope's decay value.
Default: decay
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 cutoff_sustain:

Amount of time for cutoff value to remain at sustain level in seconds. Default value is set to match amp envelope's sustain value.
Default: sustain
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 cutoff_release:

Amount of time (in seconds) for sound to move from cutoff sustain value to cutoff min value. Default value is set to match amp envelope's release value.
Default: release
must be zero or greater
Can not be changed once set
Scaled with current BPM value

 cutoff_attack_level:

The peak cutoff (value of cutoff at peak of attack) as a value between 0 and 1 where 0 is the :cutoff_min and 1 is the :cutoff value
Default: 1
must be a value between 0 and 1 inclusively
Can not be changed once set

 cutoff_sustain_level:

The sustain cutoff (value of cutoff at sustain time) as a value between 0 and 1 where 0 is the :cutoff_min and 1 is the :cutoff value.
Default: 1
must be a value between 0 and 1 inclusively
Can not be changed once set

 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: 0.1
must be greater than zero,must be a value less than or equal to 1
May be changed whilst playing
Has slide parameters to shape changes

 wave:

Wave type - 0 saw, 1 pulse, 2 triangle. Different waves will produce different sounds.
Default: 0
must be one of the following values: [0, 1, 2]
May be changed whilst playing

 pulse_width:

The width of the pulse wave as a value between 0 and 1. A width of 0.5 will produce a square wave. Different values will change the timbre of the sound. Only valid if wave is type pulse.
Default: 0.5
must be a value between 0 and 1 exclusively
May be changed whilst playing
Has slide parameters to shape changes

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
