SuperCollider implementation of the Dirt sampler, originally designed for the TidalCycles 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.

Installation from SuperCollider


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


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(<path>) 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

Options on-the-fly

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:

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.
