Hz.Reverb produces a lush reverberation effect. It is both a standalone plugin as well as a built-in module to Hz.Samplo and Hz.Syntho.
// To add a separate `Hz.Reverb` to your scene, just wire the dry
// signal to its input. Like so:
let osc = scene.NewAnode("Hz.Osc", {cfg: "stereo"});
let rez = scene.NewAnode("Hz.Reverb", {cfg: "stereo"});
scene.Chain(osc, rez, scene.GetDAC());
await scene.Sync();
// Next simply show the webview gui, it appears in the `HzPlugins` tab.
// Now, tweak parameters while the notes are playing to achieve
// reverb-bliss.
rez.Show();
// generate some sounds below
