SC-808 Maracas

use_synth :sc808_maracas

Maracas of the SC808 drum machine based on Yoshinosuke Horiuchi’s implementation of the legendary rhythm composer from the early 80s. This is a percussive synth, so it does not use the standard envelope parameters, neither does it feature slideable parameters.

Introduced in v4.5

Options

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

hpf:

High pass filter cutoff value for the maracas. A MIDI note representing the lowest frequencies allowed to be present in the sound. A high value like 100 makes the sound thin and whispy, a low value like 40 removes just the lower bass components of the sound.

Default: 113
Must be zero or greater, must be a value less than 119
May be changed whilst playing
Has slide options to shape changes

click:

Amount of initial click to the maraca sound. 0 is no click and 1 is a hard click.

Default: 1
Must be a value between 0 and 1 inclusively
Can not be changed once set

decay:

Amount of decay for the maracas. Higher numbers increase the decay duration.

Default: 0.1
Must be greater than zero
Can not be changed once set

decay_curve:

Curve value for the decay of the maracas

Default: -20
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
