To avoid problems, we warmly recommend upgrading all three components of TidalCycles together - the tidalcycles library itself, the editor plugin, and the SuperDirt synth.
Upgrade tidal with the following from a terminal window:
cabal update cabal install tidal --lib
If you're using an older version of haskell you might have to miss the `--lib` off the above command.
To upgrade your tidalcycles editor plugin (which might be referred to as an 'extension' or 'package'). In atom, you can do this via the preferences > updates menu.
In VSCode, you can upgrade the TidalCycles package by viewing your extensions (View > Extensions menu, or click on the Extensions icon on the left-hand activity bar), searching for TidalCycles and then choose to upgrade.
To upgrade the SuperDirt sound synthesiser/sampler, open supercollider, and run the following (paste it in, put your cursor on that line, hit shift-enter):
After this, you'll need to recompile the class library. You can do this either by restarting supercollider, or via the "Recompile class library" entry on the "Language" menu.
