[sdiy] updated web page describing various 'dco' schemes

[Bob Weigel]

Oh yeh I hadn't tried to make the list comprehensive yet by any means.  
I was mostly just focusing on the DCO categories.    I didn't know nco 
had become formalized terminology.  DGO just seems more intuitively 
obvious as to it's meaning for the novice.  But you're right I should 
definitely mention NCO's as I've heard some talk using the term.  I 
guess there's an order of distinction in that it's possible to digitally 
generate a signal without specifically converting numbers.  Though even 
with pwm you are doing an abstract converstion of numbers still.  It 
would be good to make that distinction also and I'll extend it in that 
realm.

btw does anyone know if a synth has been made which uses fixed fast 
pulses to do ya know..a switching power supply kind of scheme to create 
waveforms?   ie. pulsing a LP filter so as to just create an energy 
distribution that approximates the desired waveforms?

And the DK600 has an analog VCO which has analog control voltages on the 
front end of the ddn, like Polymoog.  Distinguishing it from machines 
with stable front ends and also digital approximations in pitch control 
etc.  -Bob
