 ## I saw Switch Angel using functions which I cannot find in the reference (e.g. `trancegate`). How do I make it work?
 
-Methods like `trancegate()`, `rlpf()` and `acidenv()` are currently not pattern methods which come natively with strudel.
-
 They are part of a script/prebake for strudel which was written by Switch Angel and published [here](https://github.com/switchangel/strudel-scripts)
 
 You can find the instructions how to use that script in the readme.md there.

 On the other hand, `n` is a way to reference the nth index of something. This something can be a scale (eg `n("0 2 4").scale("C:major")`) , but it can also be a particular note in a chord (see https://strudel.cc/recipes/recipes/#arpeggios for an example) .
 
-The method `n` can also be used for something completely unrelated to notes like the nth sample from a sample map `s("hh*8").bank("RolandTR909").n("0 1 2 3")`. Note that `pick` does _not_ use `n`.
