I made a saturator compressor (a non linear compressor) a few years ago

It's an external.

P.S.: @pdmtl guys It's plain wrong to have a wet/dry parameter for dynamic processing fx. It just doesn't make sense at all to have the compressor output mixed with the input signal (It not only doesn't make sense, it even adds strange phasing effects, if the the dynamic processor uses a look-ahead delay). Can we agree on that? And if not, can we discuss this, so that we finally can agree on that?That sounds like parallel (or New York) compression, which is far from being wrong. It allows for an increase in RMS without affecting the source's transient response, and in many cases this technique is far superior to series compression. A fair majority of rock/pop records of the past quarter century have had parallel compression applied to the drum bus.
In the box, latency has to be compensated for though, so you will have to delay the source to properly mix with the compressed output. You can simply send the 'dry' signal through the same compression with a 1:1 ratio and high threshold to achieve this.
I don't fully understand that last sentence: why sending the dry signal through a compression (which makes it not dry anymore) and how does threshold matter, when the ratio is 1:1 (which is basically the same as sending the signal not through a compressor at all) ?
Ok. I stand corrected. Thanks for the link. I was definitely wrong by saying, that it doesn't make sense to mix the dry signal with the compressed signal. Indeed, the effect is different from just 'destroying' the effect of the compressor (which is - simply said - lowering the output gain the higher the input gain is). With parallel compression the ratio between input and output gain above threshold is not linear anymore, but tends towards 1:1 the louder the input signal is. Or in other words: the ratio is dependent on the input gain.
