use_synth :tb303
Emulation of the classic Roland TB-303 Bass Line synthesiser. Overdrive the res (i.e. use very large values) for that classic late 80s acid sound.
Introduced in v2.0
| note: |
Note to play. Either a MIDI number or a symbol representing a note. For example:
Default: 52
|
| 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: 2
|
| cutoff: |
The maximum cutoff value as a MIDI note
Default: 120
|
| cutoff_min: |
The minimum cutoff value.
Default: 30
|
| cutoff_attack: |
Attack time for cutoff filter. Amount of time (in beats) for sound to reach full cutoff value. Default value is set to match amp envelope’s attack value.
Default: attack
|
| cutoff_decay: |
Decay time for cutoff filter. Amount of time (in beats) for sound to move from full cutoff value (cutoff attack level) to the cutoff sustain level. Default value is set to match amp envelope’s decay value.
Default: decay
|
| cutoff_sustain: |
Amount of time for cutoff value to remain at sustain level in beats. Default value is set to match amp envelope’s sustain value.
Default: sustain
|
| cutoff_release: |
Amount of time (in beats) for sound to move from cutoff sustain value to cutoff min value. Default value is set to match amp envelope’s release value.
Default: release
|
| cutoff_attack_level: |
The peak cutoff (value of cutoff at peak of attack) as a value between 0 and 1 where 0 is the :cutoff_min and 1 is the :cutoff value
Default: 1
|
| cutoff_decay_level: |
The level of cutoff after the decay phase as a value between 0 and 1 where 0 is the :cutoff_min and 1 is the :cutoff value
Default: cutoff_sustain_level
|
| cutoff_sustain_level: |
The sustain cutoff (value of cutoff at sustain time) as a value between 0 and 1 where 0 is the :cutoff_min and 1 is the :cutoff value.
Default: 1
|
| res: |
Filter resonance as a value between 0 and 1. Large amounts of resonance (a res: near 1) can create a whistling sound around the cutoff frequency. Smaller values produce less resonance.
Default: 0.9
|
| wave: |
Wave type - 0 saw, 1 pulse, 2 triangle. Different waves will produce different sounds.
Default: 0
|
| 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
