To know which sounds are available, open the [default sample map](https://strudel.tidalcycles.org/EmuSP12.json)
### Custom Samples
### Custom Sample Maps
You can load your own sample map like this:
<MiniRepl
tune={`samples({
bd: 'https://raw.githubusercontent.com/tidalcycles/Dirt-Samples/master/bd/BT0AADA.wav',
sd: 'https://raw.githubusercontent.com/tidalcycles/Dirt-Samples/master/sd/rytm-01-classic.wav',
hh: 'https://raw.githubusercontent.com/tidalcycles/Dirt-Samples/master/hh27/000_hh27closedhh.wav',
});
s("bd sd,hh*8").out()`}
/>
The `samples` function takes an object where the properties are the sound names and the values are urls to audio files.
As most sample packs will be loaded from the same location, you can set the base url using the second argument:

The `samples` function takes an object that maps sound names to audio file paths.
The second argument is the base URL that comes before each path. Make sure your base URL ends with a slash, while your sample paths do **not** begin with one.
Because github is a popular choice to dump samples, there is a shortcut for that:

### Multiple Samples per Sound
It is also possible, to declare multiple files for one sound, using the array notation:

s("<bd:0 bd:1>,~ <sd:0 sd:1>,[hh:0 hh:1]*2").out()`}

The `:0` `:1` etc. are the indices of the array.
The sample number can also be set using `n`:
For pitched samples, you can use `note`, just like with synths:
<MiniRepl

bd: ['bd/BT0AADA.wav','bd/BT0AAD0.wav'],
sd: ['sd/rytm-01-classic.wav','sd/rytm-00-hard.wav'],

If we have 2 samples with different base pitches, we can make them in tune by specifying the pitch like this:

If a sample has no pitch set, `c3` is the default.
We can also declare different samples for different regions of the keyboard:
<MiniRepl
tune={`samples({
"moog": {
'g2': 'moog/004_Mighty%20Moog%20G2.wav',
'g3': 'moog/005_Mighty%20Moog%20G3.wav',
'g4': 'moog/006_Mighty%20Moog%20G4.wav',
}}, 'github:tidalcycles/Dirt-Samples/master/');
note("g2!2 <bb2 c3>!2, <c4@3 [<eb4 bb3> g4 f4]>")
.s('moog').clip(1)
.gain(.5).out()`}
/>
The sampler will always pick the closest matching sample for the current note!
