# SuperDirt



SuperCollider implementation of the Dirt sampler, originally designed

for the [TidalCycles](https://github.com/tidalcycles/tidal)

environment. SuperDirt is a general purpose framework for playing

samples and synths, controllable over the Open Sound Control protocol,

and locally from the SuperCollider language. SuperDirt is also

used by [Sardine](https://sardine.raphaelforment.fr), a live coding

environment for Python 3.10+.

## Requirements



* SuperCollider >= v3.7 (3.6 possible, but see below): https://github.com/supercollider/supercollider

* The Vowel Quark: https://github.com/supercollider-quarks/Vowel

* optional, but recommended (many effect UGens need it): sc3-plugins: https://github.com/supercollider/sc3-plugins/

* For proper usage you need https://github.com/tidalcycles/Tidal



## Installation from SuperCollider

```

include("SuperDirt");

```

Note: this also automatically installs the DirtSamples quark, which contains a large collection of sound files. It downloads them as a zip file. Sometimes, git fails to unpack these samples and they don't get listed. In this case, you have to unpack them "manually".



## Simple Setup



`SuperDirt.start`



You can pass `port`, `outBusses`, `senderAddr` as arguments.



## Setup with options



For an example startup file, see the file `superdirt_startup.scd`. you can `load()` this from the SuperCollider startup file.



## Automatic startup

If you want SuperDirt to start automatically, you can load it from the startup file. To do this, open the sc startup file (```File>Open startup file```) and add: ```load("... path to your tidal startup file ...")```. This path you can get by dropping the file onto the text editor.



## Options on startup

- `numChannels` can be set to anything your soundcard supports

- for server options, see `ServerOptions` helpfile: http://doc.sccode.org/Classes/ServerOptions.html



## Options on-the-fly

- add sound files. `~dirt.loadSoundFiles("path/to/my/samples/*")` You can drag and drop folders into the editor and add a wildcard (*) after˘ it.

- you can pass the udp port on which superdirt is listenting and the output channel offsets: `~dirt.start(port, channels)`

- new orbits can be created on the fly (e.g. `~dirt.makeBusses([0, 0, 0])`).

- add or edit SynthDef files to add your own synthesis methods to be called from tidal: https://github.com/musikinformatik/SuperDirt/blob/master/synths/default-synths.scd

- you can live rewrite the core synths (but take care not to break them ...): https://github.com/musikinformatik/SuperDirt/blob/master/synths/core-synths.scd



## Trouble Shooting

 If you run into unspecific troubles and want to quickly reset everything, you can run the following: `SuperDirt.resetEverything`

You can minimize downtime if you have a startup file that automatically starts SuperDirt (see Automatic startup, above).



## Using SuperDirt with SuperCollider 3.6

It is in principle possible to use SuperCollider 3.6, but startup will be much slower by comparison. It is **not** recommended if you expect it to run smoothly.



For reference, we leave here the instructions if you want to try anyway:



The install works differently: don't do `include("SuperDirt")`, but instead download the three quarks to the SuperCollider `Extensions` folder:

- https://github.com/musikinformatik/SuperDirt

- https://github.com/tidalcycles/Dirt-Samples

- https://github.com/supercollider-quarks/Vowel



Note that for automatically loading the sound files, the folder `Dirt-Samples` should have this name (not Dirt-Samples-master e.g.) and should be next to the SuperDirt folder.
