    A MonoSynth is a basic subtractive synth with one oscillator

    /**
 * Create a MonoSynth
 * @param {AudioContext} context
 * @param {Object} [config]
 */

    Architecture

      const synth = instrument(ac, {

    One modulated oscillator

        oscillator: [ VCO, "vcf" ],
  • ¶

    One filter with envelope

        vcf: [ VCF, "envelope" ],
  • ¶

    One gain envelope

        envelope: [ GainEnvelope, "amp" ],

    The outut

    API
