[sdiy] How to make wavetables? What size?

[Metrophage]

There's a lot to think about!

Thanks to Phil and Ken for the tools.
Some interesting meditation on Nyquist.

Much thanks to Paul Maddox, Peter Blackett, and Harry Bissell for
helping me to understand what my issue is here. Simply put, I don't
understand EPROM addressing at all! That is basically what I am trying
to figure out, why I don't know how to organize the banks, waves, or
table data. I have read a few explanations of wavetable synths which
explain the circuitry, but without understanding the addressing it
doesn't seem that I can make EPROMs with table data of the right type,
in the right place. This is my first attempt to build anything digital
(apart from a kit), so at least now I have some idea of what I need to
learn. Like I said, "something obvious"!

And Harry, I >am< also very much interested in implementing quantizers
this way. Those are the next such project. How did you use Wave256 to
draw(?) musical scales? Now that I have EPROMs I must dust off my
windoze box again and look at all of this software so I can see what
you cats are talking about. I probably need to read some 27XXX data
sheets also. 

I am not very concerned about the sampling theorem issues here, I know
- even I was able to do the math. This is just the line between whether
or not you want a basic VCDO or a "real sampler. Who says that a wave
bank in a modular even needs to be done with old 8-bit technology?
Personally, I like my digital stuff to be very un-smooth. Crazy
parameter jumps, discrete values, ultimately what characterizes the
medium, I think. I am not aiming for a device with faithful
reproduction, but for more harmonic complexity and weirdness.

Thanks for chiming in with interesting food for thought!
