+Note that only the sample maps (mapping names to URLs) are loaded initially, while the audio samples itself are not loaded until they are actually played.
 This behaviour of loading things only when they are needed is also called `lazy loading`.
 While it saves resources, it can also lead to sounds not being audible the first time they are triggered, because the sound is still loading.
 [This might be fixed in the future](https://github.com/tidalcycles/strudel/issues/187)

-# Sounds
-
-Let's take a closer look about how sounds are implemented in the webaudio output.
-
-## Registering a sound
-
-All sounds are registered in the sound map, using the the `registerSound` function:
-
-```ts
-function registerSound(
-  name: string, // The name of the sound that should be given to `s`, e.g. `mysaw`
-  // The function called by the scheduler to trigger the sound:
-  (
-    time: number, // The audio context time the sound should start
-    value: object, // The value of the `Hap`
-    onended: () => void // A callback that should be fired when the sound has ended
-  ) => {
-    node: AudioNode, // node to connect to rest of the effects chain
-    stop: (time:number) => void // a function that will stop the sound
-  },
-  data: object // meta data, only for ui logic in sounds tab
-);
-```
-
-When `registerSound` is called, it registers `{ onTrigger, data }` under the given `name` in a [nanostore map](https://github.com/nanostores/nanostores#maps).
-
-### Example
-
-This might be a bit abstract, so here is a minimal example:
-
-```js
-registerSound(
-  'mysaw',
-  (time, value, onended) => {
-    let { freq } = value; // destructure control params
-    const ctx = getAudioContext();
-    // create oscillator
-    const o = new OscillatorNode(ctx, { type: 'sawtooth', frequency: Number(freq) });
-    o.start(time);
-    // add gain node to level down osc
-    const g = new GainNode(ctx, { gain: 0.3 });
-    // connect osc to gain
-    const node = o.connect(g);
-    // this function can be called from outside to stop the sound
-    const stop = (time) => o.stop(time);
-    // ended will be fired when stop has been fired
-    o.addEventListener('ended', () => {
-      o.disconnect();
-      g.disconnect();
-      onended();
-    });
-    return { node, stop };
-  },
-  { type: 'synth' },
-);
-// use the sound
-freq(220, 440, 330).s('mysaw');
-```
-
-You can actually use this code in the [REPL](https://strudel.tidalcycles.org/) and it'll work.
-After evaluating the code, you should see `mysaw` in listed in the sounds tab.
-
-## Playing sounds
-
-Now here is what happens when a sound is played:
-When the webaudio output plays a `Hap`, it will lookup and call the `onTrigger` function for the given `s`.
-The returned `node` can then be connected to the rest of the standard effects chain
-Having the stop function separate allows playing sounds via midi too, where you don't know how long the noteon will last
