I just tried this code. It does not seg-fault like the other code. I'm
not convinced it's the future as you mention. It doesn't sound like
you've worked that much on the laws of sound, each button or key press
produces the exactly same sound, no difference, the only way to produce
any difference is to press keys/buttons rapidly to layer the sound.

That theory could be applied to a pure DC signal but I'm not sure
if you might need another forehead or not.

Well I'm harldy going to rush out and buy Windows just so I can test
your program to see if it meets my needs am I?

And why does your program do horrible things to my terminal?

James.
