Once again, I wish I could ask my dad... He was a recording engineer for RCA in NYC in '50s, and I think also recorded NBC (or was it CBS) classical orchestra? When I was growing up I recall hearing a 78 lacquer pressing out-take of Stowkowski (?) cursing out the orchestra... but i lost track of tha...

Joel has posted his questions on several forums and the discussion has gravitated to a thread here- http://www.prodigy-pro.com/diy/index.php?topic=40053.100 I think checking out the Euphionix series was already suggested there. I have a passing interest in this, but this is not a good use of time fo...

I saw the review.. that was a big sloppy wet kiss... good job. :lol: The compression slope knob having 50% of travel allocated to < 2:1 compression, will have the beneficial result of encouraging customers to use a lighter hand when dialing in compression... always a good thing. If you were doing ex...

congrats...

Indeed a lighted switch button seems a faint criticism... I doubt anybody would not buy one because of that... But put that on the list for the next generation more expensive version.

I made studio flangers in the 70-80s and to mimmic true tape reel flanging, we would have needed two delays so the flanging could sweep all the way through zero. It seems a modern digital delay based flanger might be too clean.. IMO we need to model the phase and amplitude response of the tape machi...

JR- Just did a simple search on Digital pots. I was quite surprised on the amount available and there relatively low cost. Since i admittedly have never even breadboarded a digital pot, what kind of resolution do you think it would need to not be able to hear zipper noise... Hmmm. I am just now get...

OK, if it is current input, perhaps that is what the R in series with the other filter cap is doing. Still looks like a classic 2 pole LPF and that gives the 180' of phase shift per stage as connected, when the 2x (10k) inverted output goes away the 1x (20k) takes over.

There is another thread here already where I have described a VCA based fader and pan pot replacement that feeds into a current source sum bus topology. Digitally controlling VCAs requires D/A conversion for every analog control voltage. Use of digital pots cuts out the middle man, so to speak, as y...

I know as an engineer the ultimate console would be a fully automatable analog console. IE: Offering the same extensive automation found in DAW's. Such as EQ and Comp auto. The question is: Outside of Cost factor, How would the use of VCA's (such as That 2181/2180A) in every Pot position on a desk ...
