You can install all of the prerequisites by heading over to the prerequisite installation page.
Open a Command Prompt (or PowerShell), then type and run these two commands:
cabal update cabal install tidal
If you've never installed TidalCycles before, then the
cabal install tidal step may take some time. At the end of the command output, it should say
Installed tidal-x.x.x (where x.x.x is the latest version number) without any errors.
Start SuperCollider, and in the editor window paste in the following line of code:
Run the code by clicking on it, to make sure the cursor is on this line, then hold down Shift and press Enter. This will download SuperDirt and you will see it has completed when the Post Window displays:
... the class library may have to be recompiled. -> SuperDirt
After it has completed, you will need to restart SuperCollider (or alternatively, recompile the class library via the “Language” menu).
Install Atom Extension
Start Atom, and install the TidalCycles plugin. You can find it via the menus under edit > settings > install, then typing “tidalcycles” into the search box. Once that’s installed, restart atom.
Test Your Installation
Now you are ready to Start TidalCycles and SuperDirt for the first time.
