Reverb torture test

Reverb torture test

I was playing around with my drum machine and reverbs today, and found what seemed to be a real reverb torture test: The sample of the '808 clap that the Korg Electribe drum machine has.

All of my reverbs (PCM90 + dual-verb card; FireworX; SRV-2000; Alex) had a hard time with this sound. None of them could render the sound without some amount of flutter in the reverberant wash or a metallic edge in the reberb tail.

In particular, the PCM90 sounded like a tin can (very metallic) with this sound until I adjusted the parameters like crazy.

Even after extensivly adjusting the "Gold Plate" preset, the sound still has a metallic edge in the reverb tail if one listens carefully to it. I can change the harmonics which have the metallic edge by adjusting the plate "size"; I can also mask some of the edge of the sound by adjusting the "attack" and "shape" parameters (these change the sound of the early reflections). Maximizing the "wander" helps ("wander" has some slight randomness to the reverb; this will make pure synth tones sounds bumpy when going through; but makes unpitched sounds have a better tail); it would be nice if the '90 could allow even more wander.

I enjoy the PCM90 the most because its reverb has the most parameters; I think Lexicons will not be killed by the sampling convolution reverbs because one can endlessly tweak the reverb sound.

The FireworX is a better FX box than a reverb; the reverb was not dense or bright enough do give this '808 handclap justice.

The Alex, surprisingly enough, did not sound as metallic as the PCM90. Still, it had a ringing in the tail.

The SRV-2000, to its credit, had no real metallic sound unless I was using its RMX-16 "gate reverb" emulation. I can see why the SRV-2000 is popular as a drum reverb. Even so, different room sizes emphasized different frequencies in the reverb tail; the plates had a flutterly tail.
There is a certain "rude" sound to the SRV-2000 which the other reverbs did not have; the PCM90 sounded "shimmering" when I finally got a decent sound. The FireWorX sounded dark and did not have as much detail as I would have wanted. The Alex sounded a little 'thin'.

A sample is worth a 1000 words; I really ought to put samples up showing what I got with the "science experiment" I did today.

I ran into a similar problem a couple of month ago and the only two boxes that could handle the percussive sound where the TC M6000 and the Kurzweil KSP-8. I tried the PCM-90/80/70, Eventide DSP4000, TC M2000, TC M-one, FireWorx, Yamaha REV500 and even a spring reverb with little success. Percussion really separates the boys from the men in the reverb department.

I agree, certain percussion, particularly electronic stuff, will bring a reverb to it's knees. I still love the plate sounds in my 90, but I don't use it for much else anymore (I like working off of "great plate" the best). But when I've got that percussive sound that won't work with normal reverbs, I get out the TC M2000, NOT the M3000, but it's predecessor. The "wander" in the PCM90 is replaced in the M2000 by flat out chorusing, with speed and intensity in both engines. You can take the nastiest 12bit handclap sample and put an intense, creamy dark chocolate verb on it, with a very dense tail that goes for days.

I love good reverbs, especially the "spooky" sounding ones. Hey Michael, what do you think of the reverb in the KSP-8? How would you compare it to the 6000 or even a Lexicon? I been looking into the KSP for surround stuff, or do I wait and afford a 6000 someday?

The KSP-8 is a great machine and well woth the money (a little over $2K street). I would get the KSP now and buy the M6000 later (but look who you are asking heh ). Both units are very "high end" and have great sounding reverb algos. The 6000 does more in the compression/EQ/plug-ins department, but the KSP shines in the chorus/flange/stereo distrotion department. Both are great for surround reverbs. I am beta testing the AES card for the KSP right now (should be out very soon) and it works great with every piece of digital gear I have at WireWorld. I don't think you can go wrong with the KSP and I don't expect there to be a lot of M6000 on ebay soon heh

I've found the Yamaha Rev -5 to be one of the best kick/low drum verbs out there. It doesn't do much else for me however.

Hey SamIam, i know this was a while ago, how do you feel about posting samples of your experiment now?
