JavaScript <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Generator" target="_blank">generators</a> are powerful functions for generating value sequences. They can be used to generate melodies, rhythms or control parameters.
In Topos generator functions should be called using the <ic>cache(key, function)</ic> function to store the current state of the generator. This function takes two arguments: the name for the cache and the generator instance.
In Topos generator functions should be called using the <ic>cache(key, function)</ic> function to store the current state of the generator. This function takes two arguments: the name for the cache and the generator instance.
Once the generator is cached the values will be returned from the named cache even if the generator function is modified. To clear the current cache and to re-evaluate the modified generator use the **Shift+Ctrl+Backspace** shortcut. Alternatively you can cache the modified generator using a different name.

To find some inspiration - or to enter into the void - one can visit <a href="https://oeis.org/" target="_blank">The On-Line Encyclopedia of Integer Sequences (OEIS)</a> to find some interesting integer sequences.

Many of the sequences are implemented by <a href="https://github.com/acerix/jisg/tree/main/src/oeis" target="_blank">JISG</a> (Javascript Integer Sequence Generators) project. Those sequences can be referenced directly with the identifiers using the cache function.
