[sdiy] How to make wavetables? What size?

[Metrophage]

Hi Nate - 

Yes, it is a nice tool, except that I don't know how to make a circuit
for 256 byte tables! It'd be easier to do-it-myself if I knew what I
was doing! >;]P I do have the Wiard app around here somewhere. As I was
saying, various circuits expect the ROMs to be organized in different
ways - they are not all cross-compatable. I am sure that the basic
principle behind the Wiard app is simple, but the GUI probably removes
some of the tedium of writing the stuff in a text editor. I can endure
writing it all out, I just don't know how to format the data. Most
software which I have played with tables are just lists of frequencies
in Hertz, I don't know what kind of numbers a plain DAC0800 is
expecting.

Probably a lot of "obvious" stuff I am missing, but I'll make sense of
it!
