use_synth :chipnoise
Generates noise whose values are either -1 or 1 (like a pulse or square wave) with one of 16 particular frequencies. This is similar to the noise channel on the 2A03 chip used in the NES games console, although it lacks the same Pseudo-Random Number Generator (PRNG) and doesn’t implement the 2A03’s lesser used noise mode. The amplitude envelope defaults to moving by step to keep that 16 bit feel and this synth also has a slight soft clipping to better imitate the original sound of the device. Use for retro effects, hand claps, snare drums and hi-hats.
Introduced in v2.10
| 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
|
| 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
|
| 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
|
| decay: |
Amount of time (in beats) for the sound to move from full amplitude (attack_level) to the sustain amplitude (sustain_level).
Default: 0
|
| 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
|
| 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
|
| attack_level: |
Amplitude level reached after attack phase and immediately before decay phase
Default: 1
|
| decay_level: |
Amplitude level reached after decay phase and immediately before sustain phase. Defaults to sustain_level unless explicitly set
Default: sustain_level
|
| sustain_level: |
Amplitude level reached after decay phase and immediately before release phase.
Default: 1
|
| 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: 0
|
| freq_band: |
Which of the 16 frequency bands to use, from 0 to 15. These range from 220Hz to 225kHz as on the original chip. This arg will accept floats but round to the nearest integer to allow for sweeping through the 16 set points with envelopes.
Default: 0
