I would argue that it's not *that* lowfi ^_^, but yeah, you'd get 
coloration over time as the delay line loops. Anyway, there are much 
better toys for looping. I totally love the idea of just a delay line. 
In addition, I very much like the idea of keeping the things analog 
does well in the analog domain and the things digital does well in the 
digital domain.

For example, I think it's silly to do the filtering with a DSP 
algorithm, you end up having to code back all the variances and 
imperfections found in a real filter that make them sound good. You'll 
get better filtering from any of the 400 series anyway. Same applies 
for the mixing. What happens when the feedback overloads? In a digital 
algorithm? In a analog circuit? I think those edge conditions are 
important.

Time scaling resolution should be high enough to avoid zippering. 
Ranges are fine way to overcome this.

Just the thought of a feedback delay line that incorporates a 440 makes 
me drool ^_^

ps: has anyone else here played with the evolver? it's a dsp/analog 
hybrid.
