I'm working on a plugin aimed to do some audio damage, so I was wondering: What is the best way to create a really hard digital distortion?
Hard distortions, any ideas?

Distortion is a big subject.
A search of the forum will yield a fair bit of results
Angstrom has a neat idea here:
simple distortion

tanh is a pleasant distortion, sine is just for siliness, a basic clip is what I would call a 'hard' distortion

There's always my Waveshaper You can get as nasty as you wish with that..
Remember to get the latest version (29 I think)

for the simplest money can buy,
you could experiment with y=x-a*x^n
where 'a' is your saturation/distortion amount and 'n' is the shape. in SM you write x^4 as x*x*x*x, for example.
several of these in series and one can get pretty damn flexible (and efficient) with the waveshapes.
For those more serious about their shapers, a filtered version of a*x^n is recommended. The filter choice is yours obviously. The shaper is thus no longer what we call "memoryless", and nearly infinite flexibility is allowed, by good parametrisation and choice of co-efficients and/or order of the shaper.
Oversampling is highly recommended for anything above 2nd order.
Let's go one more level up... Asymmetry. Process each side of the signal with different shaper (making sure the zeros meet). One could even introduce asymmetry at arbitrary points of the signal.
Serialisation and parallelisation of these blocks has been the building ground for stompbox distortion designers for more than 50 years now. 😉
There are no rules. You do what sounds good.

Ok I'm stuck in the recent example. Here is my code, and it generates an error that I can't pin down at the last order:
Can anyone help me here?
monoout y; monoin x; monoin a; monoin n;
y=x-a*x^n;

you gotta do power with multiplication. x^4 is x*x*x*x
Maybe a loop could be used to get there dynamically.

Also it is possible to do this with regular SM math modules easily.

The code component does not support power.
However, there's something on the wiki: Fast Power Approximation
