note-player-stream v1.0.2

note-player-stream

Plays different notes with the Web Audio API based on a stream of input

This module expects to be used with web-midi-note-stream, but accepts any stream which outputs objects that look like the following:

{
	pressed: Boolean, // Whether the button has been pressed/released
	note: Number, // Integer between [0-127] which represents a midi note
	frequency: Number, // The frequency to play the oscillator at (note required for custom nodes)
}

Usage

Install:

npm install --save note-player-stream

Require:

var playerStream = require("note-player-stream");
var player = playerStream({type: "square"});

Example

This example will listen for input from a Launchpad and play sound when a button is pressed

var playerStream = require("note-player-stream");
var noteStream = require("web-midi-note-stream");
var webMidi = require("web-midi");

webMidi("Launchpad")
	.pipe(noteStream())
	.pipe(playerStream());
