A pair of detuned pulse waves passed through a low pass filter. Two pulse waves with slightly different frequencies generates a nice thick sound which can be used as a basis for some nice bass sounds. Thicken the sound by increasing the detune value, or create an octave-playing synth by choosing a detune of 12 (12 MIDI notes is an octave). Each pulse wave can also have individual widths (although the default is for the detuned pulse to mirror the width of the main pulse).

Introduced in v2.8

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

detune:

Distance (in MIDI notes) between components of sound. Affects thickness, sense of tuning and harmony. Tiny values such as 0.1 create a thick sound. Larger values such as 0.5 make the tuning sound strange. Even bigger values such as 5 create chord-like sounds.

Default: 0.1
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

dpulse_width:

The width of the second detuned 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: pulse_width
Must be a value between 0 and 1 exclusively
May be changed whilst playing
Has slide options to shape changes
