-## Usage
-
-```sh
-# Setup
-# - make sure node >= 20 is installed
-# - make sure pnpm is installed
-cd packages/node
-pnpm i
-# Usage
-pnpm start
-```
-
-Then run `sclang` with superdirt in another terminal.
-
-You can now edit and save the file `pattern.mjs` to update your pattern!

 # Loading Custom Samples
 
-You can load a non-standard sample map using the `samples` function.
+You can load your own sample map using the `samples` function.
+In this example we create a map using sounds from the default sample map:
 
-## Loading samples from file URLs

+  bd: 'bd/BT0AADA.wav',
+  sd: 'sd/rytm-01-classic.wav',

+}, 'https://raw.githubusercontent.com/tidalcycles/Dirt-Samples/master/');
+s("bd sd bd sd,hh*16")`}
+/>
 
-In this example we assign names `bassdrum`, `hihat` and `snaredrum` to specific audio files on a server:
+When you load your own samples, you can choose the names that you will then refer to in your pattern string inside the `s` function.
+Compare with this example which uses the same samples, but with different names.

   tune={`samples({
   bassdrum: 'bd/BT0AADA.wav',
+  snaredrum: 'sd/rytm-01-classic.wav',

- 
-s("bassdrum snaredrum:0 bassdrum snaredrum:1, hihat*16")`}
+s("bassdrum snaredrum bassdrum snaredrum, hihat*16")`}
 />
 
-You can freely choose any combination of letters for each sample name. It is even possible to override the default sounds.
-The names you pick will be made available in the `s` function.
-Make sure that the URL and each sample path form a correct URL!
+Here we have changed the "map" to include longer sample names.
 
-In the above example, `bassdrum` will load:
+## The `samples` function
 
-```
-https://raw.githubusercontent.com/tidalcycles/Dirt-Samples/master/bd/BT0AADA.wav
-|----------------------base path --------------------------------|--sample path-|
-```
+The `samples` function has two arguments:
 
-Note that we can either load a single file, like for `bassdrum` and `hihat`, or a list of files like for `snaredrum`!
-As soon as you run the code, your chosen sample names will be listed in `sounds` -> `user`.
+- A [JavaScript object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object) that maps sound names to audio file paths.
+- A base URL that comes before each path describing where the sample folder can be found online.
+  - Make sure your base URL ends with a slash, while your sample paths do **not** begin with one!
 
-## Loading Samples from a strudel.json file
+To see how this looks in practice, compare the [DirtSamples GitHub repo](https://github.com/tidalcycles/Dirt-Samples) with the previous sample map example.
 
-The above way to load samples might be tedious to write out / copy paste each time you write a new pattern.
-To avoid that, you can simply pass a URL to a `strudel.json` file somewhere on the internet:
+Because GitHub is a popular place for uploading open source samples, it has its own shortcut:
 
 <MiniRepl
   client:idle
-  tune={`samples('https://raw.githubusercontent.com/tidalcycles/Dirt-Samples/master/strudel.json')
+  tune={`samples({
+  bd: 'bd/BT0AADA.wav',
+  sd: 'sd/rytm-01-classic.wav',
+  hh: 'hh27/000_hh27closedhh.wav',
+}, 'github:tidalcycles/dirt-samples');
 s("bd sd bd sd,hh*16")`}
 />
 
-The file is expected to define a sample map using JSON, in the same format as described above.
-Additionally, the base path can be defined with the `_base` key.
-The last section could be written as:
+The format is `github:user/repo/branch/`.
 
-```json
-{
-  "_base": "https://raw.githubusercontent.com/tidalcycles/Dirt-Samples/master/",
-  "bassdrum": "bd/BT0AADA.wav",
-  "snaredrum": "sd/rytm-01-classic.wav",
-  "hihat": "hh27/000_hh27closedhh.wav"
-}
-```
-
-## Github Shortcut
-
-Because loading samples from github is common, there is a shortcut:
+Let's see another example, this time based on the following GitHub repo: https://github.com/jarmitage/jarmitage.github.io.
+We can see there are some guitar samples inside the `/samples` folder, so let's try to load them:
 
 <MiniRepl
   client:idle
-  tune={`samples('github:tidalcycles/dirt-samples')
-s("bd sd bd sd,hh*16")`}
+  tune={`samples({
+  g0: 'samples/guitar/guitar_0.wav',
+  g1: 'samples/guitar/guitar_1.wav',
+  g2: 'samples/guitar/guitar_2.wav',
+  g3: 'samples/guitar/guitar_3.wav',
+  g4: 'samples/guitar/guitar_4.wav'
+}, 'github:jarmitage/jarmitage.github.io/master/');
+s("<g0 g1 g2 g3 g4>/2")`}
 />
 
-The format is `samples('github:<user>/<repo>/<branch>')`. If you omit `branch` (like above), the `main` branch will be used.
-It assumes a `strudel.json` file to be present at the root of the repository:
+## Multiple Samples per Sound
 
-```
-https://raw.githubusercontent.com/<user>/<repo>/<branch>/strudel.json
-```
-
-## From Disk via "Import Sounds"
-
-If you don't want to upload your samples to the internet, you can also load them from your local disk.
-Go to the `sounds` tab in the REPL and press "import sounds".
-Then you can select a folder that contains audio files. The folder you select can also contain subfolders with audio files.
-Example:
-
-```
-└─ samples
-   ├─ swoop
-   │  ├─ swoopshort.wav
-   │  ├─ swooplong.wav
-   │  └─ swooptight.wav
-   └─ smash
-      ├─ smashhigh.wav
-      ├─ smashlow.wav
-      └─ smashmiddle.wav
-```
-
-In the above example the folder `samples` contains 2 subfolders `swoop` and `smash`, which contain audio files.
-If you select that `samples` folder, the `user` tab (next to the import sounds button) will then contain 2 new sounds: `swoop(3) smash(3)`
-The individual samples can the be played normally like `s("swoop:0 swoop:1 smash:2")`.
-
-## From Disk via @strudel/sampler
-
-Instead of loading your samples into your browser with the "import sounds" button, you can also serve the samples from a local file server.
-The easiest way to do this is using [@strudel/sampler](https://www.npmjs.com/package/@strudel/sampler):
-
-```sh
-cd samples
-npx @strudel/sampler
-```
-
-Then you can load it via:
+It is also possible, to declare multiple files for one sound, using the array notation:
 
 <MiniRepl
   client:idle
-  tune={`samples('http://localhost:5432/');
- 
-n("<0 1 2>").s("swoop smash")`}
+  tune={`samples({
+  bd: ['bd/BT0AADA.wav','bd/BT0AAD0.wav'],
+  sd: ['sd/rytm-01-classic.wav','sd/rytm-00-hard.wav'],
+  hh: ['hh27/000_hh27closedhh.wav','hh/000_hh3closedhh.wav'],
+}, 'github:tidalcycles/dirt-samples');
+s("bd:0 bd:1,~ <sd:0 sd:1> ~ sd:0,[hh:0 hh:1]*4")`}
 />
 
-The handy thing about `@strudel/sampler` is that it auto-generates the `strudel.json` file based on your folder structure.
-You can see what it generated by going to `http://localhost:5432` with your browser.
+The `:0` `:1` etc. are the indices of the array.
+The sample number can also be set using `n`:
 
-Note: You need [NodeJS](https://nodejs.org/) installed on your system for this to work.

+}, 'github:tidalcycles/dirt-samples');
+s("bd bd,~ sd ~ sd,hh*8").n("<0 1>")`}
+/>
 
-## Specifying Pitch
+In that case, we might load our guitar sample map a different way:
 
-To make sure your samples are in tune when playing them with `note`, you can specify a base pitch like this:
+<MiniRepl
+  client:idle
+  tune={`samples({
+  guitar: [
+    'samples/guitar/guitar_0.wav',

+  ]
+}, 'github:jarmitage/jarmitage.github.io/master/');
+s("<guitar:0 guitar:1 guitar:2 guitar:3 guitar:4>*2")`}
+/>
+
+And as above, we can choose the sample number using `n` for even more flexibility:
+
+<MiniRepl
+  client:idle
+  tune={`samples({
+  guitar: [
+    'samples/guitar/guitar_0.wav', 
+    'samples/guitar/guitar_1.wav', 
+    'samples/guitar/guitar_2.wav', 
+    'samples/guitar/guitar_3.wav', 
+    'samples/guitar/guitar_4.wav'
+  ]
+}, 'github:jarmitage/jarmitage.github.io/master/');
+n("<0 1 2 3 4>*2").s("guitar")`}
+/>
+
+## Pitched Sounds
+
+For pitched sounds, you can use `note`, just like with synths:
+
+<MiniRepl
+  client:idle
+  tune={`samples({
+  'gtr': 'gtr/0001_cleanC.wav',
+}, 'github:tidalcycles/dirt-samples');
+note("g3 [bb3 c4] <g4 f4 eb4 f3>@2").s('gtr').gain(.5)`}
+/>
+
+Here, the guitar samples will overlap, because they always play till the end.
+If we want them to behave more like a synth, we can add `clip(1)`:
+
+<MiniRepl
+  client:idle
+  tune={`samples({
+  'gtr': 'gtr/0001_cleanC.wav',
+}, 'github:tidalcycles/dirt-samples');

 - `mix` - structures from both patterns are combined, so that the new events are not fragments but are created at intersections of events from both sides.

-- `reset` is similar to `squeezeout` in that cycles from the right are aligned with events on the left. However those cycles are not 'squeezed', rather they are truncated to fit the event. So `"0 1 2 3 4 5 6 7".add.reset("10 [20 30]")` would be equivalent to `10 11 12 13 20 21 30 31`. In effect, events on the right 'reset' cycles on the left.
+- `reset` is similar to `squeezeout` in that cycles from the right are aligned with events on the left. However those cycles are not 'squeezed', rather they are truncated to fit the event. So `"0 1 2 3 4 5 6 7".add.trig("10 [20 30]")` would be equivalent to `10 11 12 13 20 21 30 31`. In effect, events on the right 'trigger' cycles on the left.
 - `restart` is similar to `reset`, but the pattern is 'restarted' from its very first cycle, rather than from the current cycle. `reset` and `restart` therefore only give different results where the leftmost pattern differs from one cycle to the next.
 
 We will save going deeper into the background, design and practicalities of these alignment functions for future publications. However in the next section, we take them as a case study for looking at the different design affordances offered by Haskell to Tidal, and JavaScript to Strudel.
