var trigger = new BEEP.Trigger( '2Eb', function(){ // Let’s call this our “Foundation Voice” // because it will sing the intended Note. this.voices.push( new BEEP.Voice( this.note, this.audioContext ) .setOscillatorType( 'sine' ) .setGainHigh( 0.4 ) ) // This Voice will sing a Perfect 5th above the Foundation Voice. this.voices.push( new BEEP.Voice( this.note.hertz * 3 / 2, this.audioContext ) .setOscillatorType( 'triangle' ) .setGainHigh( 0.1 ) ) // This Voice will sing 2 octaves above the Foundation Voice. this.voices.push( new BEEP.Voice( this.note.hertz * 4, this.audioContext ) .setOscillatorType( 'sawtooth' ) .setGainHigh( 0.01 ) ) // This Voice will sing 1 octave below the Foundation Voice. this.voices.push( new BEEP.Voice( this.note.hertz / 2, this.audioContext ) .setOscillatorType( 'square' ) .setGainHigh( 0.01 ) ) })
