Adding custom noises to OS?

[Tango_king666]

First of all, that wouldn't be a synth, a synth is an artificial sound produced using math. Second of all, copyright issues exist. Third of all, there is already a real custom synth, you just have to not be actually blind to see it

I did not mean synth, even though I did write it there. I mean like a sound that changes pitch, but I cant argue, copyright is a thing.
