Hi folks
i wonder if anyone had any advice on emulating those classic
brian eno / fripp like eventide patches where a huge reverb is harmonised ? and can anyone point me in the direction of some presets as good starting points for creating very very very long reverbs with harmonised tails etc and the best modules to implement harmonisation on the kyma system.

many thanks

I'm not sure what you mean by harmonized reverb tails.

The classic "frippertronics" effect that Eno developed for Fripp was simply a long (5 sec or so) delay line with a lot of feedback. Frip would play the guitar with ebow or volume pedal fades into the delay, then harmonize with himself as the earlier notes very slowly decayed.

This made washes of harmonized textures - is that the effect you are after? It's really easy in Kyma.

Hi bill

i know the tape loop effects you mean but this is more the later work of theres where fripp uses 2 x eventide H8000.I know they are complex devices but alot of the times its just very large reverbs and then harmonisation and some echo , play in 1 note off a guitar or synth and out comes a cloud like ' huge space ' effect.I guess what i am after is huge cavenous reverbs with chordal tails or vice versa ( as the result of a harmoniser in the kyma patch or a module or series that can create a nice harmonised series of notes off the fundemental one plays)Simple stuff really i guess but i wondered if anyone had made a kyma 'emulate an eventide ' or harmoniser style patch or if theres a preset which can be a leaping block into making some some.I am new to kyma so a novice in the most extreme sense and really looking to use the Kyma system for creating large spaces / reverbs and soundscapes where 1 note becomes a whole universe.

best wishes

matt

One area to investigate might be the Granular Reverb.

HarmDelay.kym

 

I've not played with a H8000, but based on your description, I whipped up a couple examples.
I have a 5 card system so you may need to tweak them as they do take up a fair chunk of DSP.
For example, you don't need 4 reverb voices, 2 is fine for stereo and just split before the pitch shifter. However with four you can control separate decay & cutoff per reverb voice (not done in this example).

The standard Euverb doesn't have that huge of tail so you may need to build another one.

Another prototype to check out would be the Stereo Tuned Plate Reverb under the Reverb section.

Hi, sometimes ago I have created a version of an Eventide algorithm. I have created it because I had read that Eno and Fripp used it on their Eventides. Download the SweptLand.kym Sound from the kyma-tweaky: http://www.symbolicsound.com/cgi-bin/bin/view/Share/Sounds#Effects_Processing

... put the "resonz" preset and welcome to enoscape-worlds... this preset is very sensitive to the input, be careful.
Read the Discussion page on tweaky to have more information.

Eventides are great, they have all the job done, but they are not easy to reprogram, its edit software vSig it's a bit confusing. Kyma can do anything that an Eventide does. The only thing it's to know the algorithms and the presets. That's the key. Well, reverbs need more job, but by experimentig you will create your own spaces, imo this is more funny
Emulating algorithms is a great first step, but Kyma offers much, much more than an Eventide: CrossFilter, Tau, File Readers... imagine how to put all this in your new chorus or resonant delay and you will have a unique effect.

I updated the version that was posted here and posted it at on the Tweaky under Effects. http://www.symbolicsound.com/cgi-bin/bin/view/Share/Sounds

It basically will run forever now.

Input > Delay > Reverb > Pitch Shifter

Has 7 different feedback controls (feedback loops back and differing spots), 4 voices, flutter on the delay line, and some filters to keep some of it under control.

Requires a minimum 5 cards though.

thanks for the tips and examples folks ,really appreciate these , off to try them out now and then try and reinvent again , so many possibilities !

best wishes

Just to add to the discussion.

Valhalla DSP has created a VST plugin that is being described in this discussion. Here is a blog entry that has a bit more info as to what the effect is:

The Eventide range (H3000,DSP, Orville and H8000) have all been lust items for myself and buddies for many years. My lust for such units began early on in my career after learning that most of the effects and moments in many records I hold in high regard where indeed created using eventide products. (was comparatively later that my Kyma obsession takes over)

One of our first big commercial projects I was involved with produced enough money for us to split the money on a down payment on our studio and purchase the Eventide Orville. This unit became the mainstay reverb and outrageous effects for many years until we upgraded for the more digitally equipped (and powerful) H8000. Beyond the obvious quality of the hardware and converters it is the years of pedigree Alg development that really sets it apart from many products out there. ( I also think the SoundToys plugs are fantastic, I heard a rumour that they are EX Eventide.You can really hear it in the Crystalliser!)

I do tend to use my tools for the jobs for which they where designed, however I am so in-love with the 'Demon Delay'. (512 on the H8000). It features Non linear time and amplitude delay shapes in musical divisions. (linear and exponential curves) I would like to introduce similar processes in my Kyma work

Beyond the reverbs this is probably our most used patch, it is fantastically musical .

The closest thing I can reference is the accelerating sequencer/sampler.

I did think I may of read a discussion and reference to a delay with similar characteristics. Daymed if I can find it now.

I will record some 'Demon Delay' when I next make it to the studio.

Other challenges include emulations of 'EchoSpace of God'

Also, many of the reverbs have this wonderful pitch glide, I find a slow descending pitch element works wonders for the epicness.

I have created very similar effects with the feedback-memory writer. Pretty cool.

I think I did a demon delay clone in Kyma once using the replicator. IIRC Kyma crashed on me though before I saved the thing :-( The linear delay slopes are easy to create with voice number * spread value, and amp/voice number or 1-(amp/voicenumber).

Demon Delay is one of my favorite DSP4k/H8k FX, too, btw.

OH! The replicator! Of course, great stuff, the answer to most of my problems!

Thanks Denis!

As a side note.

This is my new favorite reverb. It's algorithmic but can do everything from subtle to extreme unnatural but wonderful effects.

I have tried to upload a sound to this thread but the forum tells me the .kym file is invalid... ? What am I doing wrong?

jitterverb.kym

 
OK, using Firefox seems to work.

This is a fairly light reverb, made out of 6 delays per channel, then cross-fed to the other channel. There is some jitter on the delays, and a reverb on the input, not in the feedback loop.

All the delays are prime numbers on the times, but they also vary slightly in time using the same expression for all of them. It makes for pretty cavernous reverbs and sounds a little Eno-like, that's why I uploaded it. Be careful with high Master feedback settings...


I love the Valhalla blog BTW! Lots of inspiring ideas there.

Sounds great!

Perhaps need to whip up a replaceable stereo input...

I may have a go later on..

Nice work.

jitterverb-Replaceable.kym

 
And here ya go. It does evoke some 'tide' feelings.

Thanks again!

I look forward to checking out the new uploads.

RobSol, the following link (Gearslutz) has Sean from Valhalla, Casey from Bricasti and a few others discussing Reverb implementations:
http://www.gearslutz.com/board/geekslutz-forum/380233-reverb-subculture.html

Enjoy.

Thanks for that Charlie, I will remember to make a replacable input next time.

And thanks driskel too! I will read that thread closely when I get time.


... I am thinking of a way to make the reverb even more mushy, by killing all transients on the input. I remember seeing a Transient Attack sound in the Tweaky, hmmm. A cross filter with slow attack would do it too.

Oh, but a pleasure sir, you worry about the epic patches, I will take care of the housekeeping.

re: killing transients

OTOH, an effective way of doing that is by taking the RMS of your signal, computing the derivate, then multiplying your signal with <1-d*amt>, with d being the RMS derivate and amt being an "amount" control in the range 0-2 to adjust the amount of transient reduction.

Hmm, ok I will give it a go - it will take me a litte time and concentration to work that one out in Kyma I think. I am self taught in maths on this level but love a challenge.

Thank you!
