Bassdrum of the SC808 drum machine based on Yoshinosuke Horiuchi’s implementation of the legendary rhythm composer from the early 80s.

Introduced in v4.5

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: 32
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

decay:

Internal decay of the bass drum in seconds. Drive it up to 5 or so, in order to get that bass carpet, often featured in hip-hop. Note, you need to increase the duration of the envelope (e.g. the release: opt) to hear this internal decay.

Default: 2
Must be zero or greater
Can not be changed once set

decay_curve:

Curve value for the decay of the bass drum

Default: -7
Can not be changed once set

attenuation:

Base frequency attenuation. Use values around 0.2 or lower for giving the bassdrum a more artificial sound.

Default: 1
Must be zero or greater
Can not be changed once set

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
