Re: Some things, zeroes and ones just can't do. [Warning: Long-ish read)
My view on it, not that anyone really cares....
Right now digital and analog are different and distinguishable. The two questions are:
-Is the difference enough for me to care?
-Which do I prefer?
As TimmyPage says, you may prefer digital chorus and digital delay but analog phase and univibe. Just like amps, some prefer solid state power amps, they perform differently so try many and choose what you prefer.
As far as modeling, it comes down to three (maybe 4) things:
-What are you modelling? (I agree you need to get into individual component non-linearities to get closer to original gear)
-Having a good math model for it (knowing what to model and actually creating the digital equations are two different things)
-DSP Power (you need enough power to run the simulations to the detail you've modeled)
-A/D and D/A quality (without a good conversion to and from the digital world, none of the above matters)
Eventually we'll get to the place where all those items are advanced enough that modeling will be basically unmistakable for the original stuff.
TimmyPage, some of that "darkening" is an impedance issue with older boxes. A lower input impedance than modern boxes will darken the tone some and that's the way we are used to hearing it. A lot of Univibes now have a "vintage" and "modern" switch which makes the impedance a more modern and higher value.
