ODP: Digital DIY synths?

[Roman Sowa]

Hi Ben and all,

Good to hear that someone is into DSP too...
Like others said, it is somehow harder to DIY in digital
and less fun too (at least for me), but things like
frequency shifter, or strange waveshaping I'd only
do in DSP.
I was very much convinced that my next gear would be
all-DSP until I subscribed to this list.
It's nice to have drift-free oscilators and excellent tracking
filters, but it involves so much of hitting-the-PC-keyboard...
and when you do analog, whatever you do it works in some way
not exactly what one wants, but nice too. with DSPs it's just
a matter of small error to have no signal at DAC output.

I'll return to this subject anyway, but first few analogs will
appear. I have some experience with this particular DSP
so maybe we could build something with it.

BTW seems like you have ezkitlite...
I never liked it, so I made my own system.
if you like, you might take a look:

This isn't the best way to introduce my new (or rather first)
website since it's not finished yet (and never will be...)
But anyhow many thanks to all who replied to my question
regarding website providers.
And special thanks to greg.

Roman
