JukeGen

procedually generated jukebox

Install

$ npm install jukegen

or

$ yarn add jukegen

Use

import JukeGen from 'jukegen';

let jg = new JukeGen();

jg.start();

JukeGen will do all setup on init. Start with .start(), stop with .stop().

Once JukeGen is playing it will regenerate a new piece of melody every 8 seconds (or two meassures) matching the base note and scale it picked during init.

API

A JukeGen object exposes some getters:

.getTime to get the current seconds of playing. This resets after 8 seconds but you can count up yourself.

.getFft Fourier Transform information of what's playing, can be used to visualise.

.getBpm gets beats per minute, default is 120.

.getTension tension defines the maximum step (in semitones) two notes can be apart when a new piece of melody is generated. Default is 4.

.getVolume gets the volume.

.getDistortion JukeGen comes with a distortion node plugged in initialized with ToneJS's default value but .wet set to 0. This gets the distortion.wet.value.

.getPhaser JukeGen also comes with a phaser effect node, set to the example from the ToneJS docs and .wet set to 0. This gets the phaser.wet.value.

.getChorus JukeGen also comes with a chorus effect node, set to the example from the ToneJS docs and .wet set to 0. This gets the chorus.wet.value.

and some setters:

.setBpm(int) set the beats per minute on the Tone.Transport.

.setTension(int) tension defines the maximum step (in semitones) two notes can be apart when a new piece of melody is generated. Should be a natural number.

.setVolume(int) sets the volume in decibel from 0 (start).

.setDistortion(int) sets the value of distortion wetness, should between 0 and 1.

.setPhaser(int) sets the value of phaser wetness, should between 0 and 1.

.setChorus(int) sets the value of the chorus wetness, should between 0 and 1.

No tests?

No, mostly because I gave up on configuring webpack and mocha after two hours. But it is somewhere on my todo list.
