[sdiy] VCO saw integrator cap questions

[Carsten Tönsmann]

Why should I do FM with an DCO? For this purpose I use my VCOs of course 
:-)) DCOs never are replacements for VCOs, there are tasks for both types of 
oscillators.

Your digital Filter will certainly sound fantastic, but it certainly will 
not sound like my analogue implementation. I built two of them, they both 
sound good, and both sound TOTALLY different. If you build up two instances 
of your filter with DSPs, will they sound different or identically?
