Thank you Sean for your explanationvalhallasound wrote:
The taps marked Lsum go to the left output, and Rsum go to the right output. The tap at the end of the delays (D3, D6, D9, D12) go into the inputs of the next 2AP/1-delay "block."
yes it's amazing,i can hear those patterns too,maybe duo to large delay line lengths.
The single loop has a much richer sound, for the most part, as each signal gets to travel through the entire loop before it is repeated. Much more thorough mixing. The parallel loops have smaller subsections repeating. I think that the MC202 demo reverb has parallel loops. I can hear some pretty obvious patterns, but it works for that material.
thank you sean,i will check those algo's,i've only seen that single loop of FV-1 on your valhalladsp website.
There are enough Keith Barr written algorithms on the Spin Semiconductor site to keep people busy! Most of the other Alesis algorithms are far from "perfect," but they are certainly interesting. My guess is that, if you experiment with a bunch of allpasses in a loop, or a few loops, you can get close.
ebay ,here i goAs far as strict reverse engineering, this probably won't happen anytime soon, primarily due to financial reasons. The Lexicon boxes get reverse engineered a lot, but the original hardware stills sell for $2K to $5K or more. The Alesis boxes can often be found for under $50. It takes a LOT of time to reverse engineer something by ear, even if you have a good idea of what the internals of the algorithm are, so there has to be a return on the investment.
Personally, I look at the Alesis stuff as inspiring ideas for future work, versus some "holy writ" that needs to be exactly copied. If you want the EXACT Midiverb II sound, it is still cheaper to buy the original box than, say, a hypothetical ValhallaMidiverbII.
They are cheap these days..
