A simple triangle wave with a low pass filter.

Introduced in v2.0

Options

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 options 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, 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

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 sound is 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 options to shape changes

attack:

Amount of time (in beats) 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 beats) 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 beats) 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 beats) 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

decay_level:

Amplitude level reached after decay phase and immediately before sustain phase. Defaults to sustain_level unless explicitly set

Default: sustain_level
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:

MIDI note representing the highest frequencies allowed to be present in the sound. A low value like 30 makes the sound round and dull, a high value like 100 makes the sound buzzy and crispy.

Default: 100
Must be zero or greater,must be a value less than 131
May be changed whilst playing
Has slide options to shape changes

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 options to shape changes

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
