Reverberator in TS and React

[JanVeb]

Hi there, looking how to add reverb TO piano sound but nothing works

    const webFontPlayer: any = new WebAudioFontPlayer();
    webFontPlayer.loader.startLoad(
      this.ac,
      this.nameToUrl(soundId, "JCLive", "sf2"),
      this.soundFontNameBuilder(soundId, "JCLive", "sf2")
    );
    const self: any = this;
    webFontPlayer.loader.waitLoad(function () {
      self.memoryLoadedSoundFonts.set(soundId, webFontPlayer);

// TRYING TO ADD REVERB HERE
      // var reverberator = webFontPlayer.createReverberator(this.ac);
      // var equalizer = webFontPlayer.createChannel(this.ac);
      this.echo = webFontPlayer.createReverberator(this.ac);
      this.echo.wet.gain.setTargetAtTime(1.5, 0, 0.0001);
      // var input = equalizer.input;
      // equalizer.output.connect(reverberator.input);
      // reverberator.output.connect(this.ac.destination);
      // reverberator.wet.gain.setTargetAtTime(1.5, 0, 0.0001);
    });
  }
