Martin,

Sorry, but <sigh>.

It's also EXACTLY what I've been saying too...the fact that the tonality
isn't mapped 1:1 via "dithering" is undisputable, and has never been an
issue with me.  What Jon said didn't answer my question.

My interest is if Piezo can even print near that many tones as he has
claimed (1000), as well as can we even see them....as well as, if it does,
how does it derive them.  His comment had nothing to do with that,
unfortunately.

The reason I didn't post that part of his post is because it is still
inconclusive, and I've asked more questions of him to try to get answers to
this.  The dithering part, I believe, he has answered as well as he's going
to answer it.

Regards,

Austin
