[sdiy] Walsh Generators

[Glen]

Hi,

I know there has been some mention on this list of Walsh function
generators being used for additive synthesis. What I would like to know is:

Are Walsh generators viable candidates for additive synthesis in software,
or are they primarily an idea that appeals to hardware implementations?

Why don't we hear more about the technique? Is there some big drawback?

I find it odd that all the commercial additive synthesis that I'm aware of
uses sine waves, and obviously doesn't use Walsh functions, yet the Walsh
generator is sometimes mentioned as a viable alternative. If it's truly a
viable alternative, then why hasn't someone built a commercial synth using
this technology?

I'm very curious.


thanks,
Glen
