So excited! Is there anything in particular that pre-orderers can do to help the campaign?

In! Was tempted by the Pod option, but I think i'm going to end up with a MakeNoise Skiff that has the E520 and my other "effects" in it (like the Recovery Cutting Room Floor & Pearl, etc), along with my ES-9 for sending stuff into / out of the computer. Conceptually, it'd look neat to put it right next to my E370, but I conceptually think of the E370 as the "start" of the system and the E520 will be the "end" so in my mind they can't really go next to each other.

Son of a gun. I'm finding myself considering jumping on the bandwagon for the spectral effects. Personal finances be damned!

Info copied from the YouTube description below.

Here's the early prototype of the new E520 Hyperion Processor from Synthesis Technology. To me this is really the next generation of audio processing and FX in the Eurorack format. Having the prototype to play around with I wanted to get this out to show you the great sounds already in the unit, which is constantly getting updates and new features even at this stage. Head to the links below to support it on Kickstarter and for more info.

very cool ben, great to see (and hear) it in action. well done!

while watching the video, i wondered if paul and the team had considered developing any comb filter algos. stereo combs (with a bit of distortion) are endlessly pleasing to my ears.

Bother the Phaser and the Flanger are comb filters. If you want them 'fixed', just turn off the LFO modulation,

yeah,
now build some funky "spectral shitz" into the feedback path of comb filters,
then we´re speaking. ;)


and how about Freq shifters directly interwoven into Feedback paths ?
i´ve never seen such :despair:


and now combine both.......and we leave the territory what we can patch "diy". ;)


and how about a series of comb filters with predefined morph controls under the hood ?
for funky Funs. Percussions etc.



how about to grab some tiny snippets from your live In audio stream and blow these snippets up with fancy resonators ?
again: morph controls and fancy filtering within the feedback paths



and: speaking in general: are you Folks ever implementing "compression within feedback pathes + deriving control signals from the compressor like a comp would do ( ENVFollow) and then controlling filters within that feedback path by the compresor thats in that feedback path ?
Bring wild blooming under control and even further, use it as a cadeaux to form the sound.


what i see, and as far i can tell has this module the same processing power like the "spectralis" has/had.
The Spectralis was immense ( spectralis had a 500mhz CPU running under the hood )
For sale:........it won´t sell, so i stopp bother you ;)

Any chance the comb filters can track 1v/oct. ?

The flanger algorithm has a "frequency" input mode that is exponential and can be dialed in nearly 1V/Oct. Because the CV paths on the module are run thru attenuators they're not calibrated the way the 1V/Oct on an oscillator would be, but it's pretty close.

Note the the flanger can also be set up for Karplus-Strong type resonant feedback. You can ping it with raw impulses or run them thru the diffuser for less plucked and more bowed sounds.

With goal #2 achieved to make each channel more independent from the other, would it make sense to have separate sync inputs for each channel? Wondering if this would also allow for the same or different effects in each channel to be triggered/ synced separately at different rates, then mixed in or out of phase internally or by an external module after output to find sweet spots. If panel space is an issue, could use a stereo input jack with a split input cable for separate syncs and have a mono plug in controlling both channels the same. Just thinking out loud.

Thanks to a strong 'Black Friday' and 'Cyber Monday' surge, we have crossed $80K and the 2nd of 4 Stretch Goals.

I now wish to explain EXACTLY what to expect when you get this unit, as there have been questions about "chaining" and what it means in the E520.
Many people have asked since the launch: "can I chain effects?" and I have always taken this to mean "can I pick 1 of 32 to be in front, followed by another effect?" and the answer has always been no.

The UI and CV scheme doesn't support it, the patch manager doesn't support it, and the ARM speed is just not fast enough to chain certain algorithms. The main reason is this: if each algorithm uses all 4 CV inputs, and you chain that to another one that needs 3, how is this even done?

So, what exactly DO you get with Stretch Goal #2. The short answer is: well-defined factory presets that are a compromise in sharing the CVs to make the overall algorithm manageable. And, you are getting 2 TYPES of 'chaining': a stereo algorithm on a chain, and also 2 completely different algorithms on L/R signal paths. Let's discuss each.

The first set of algorithms will be 2 effects in a chain, which are in stereo. This will be most like current algorithm, but not as many controls for each 'block'. What we will have to decide on carefully is what does "feedback" do? Is it a feedback "of the chain"? Maybe the best use is a feedback around only 1 of the 2 'signal blocks' (like around a Delay to get repeats). This will take a lot of beta testing, tweaking, and arguments.
The second type will be what I will call a 'Split': like a delay on Left and a Shimmer on Right, but these are MONO effects. Now what is cool is that with 1 patch cable, you now can have them 'chained' as well. Again, each algorithm will be a CV/options reduced version from the "originals". IN MONO.

Lastly, the production patch memory will double from the breadboards which will allow the 'chained' and 'split' patches not to "count" against the 32 maximum total. There still can be 32, stereo, single algorithms, and probably 16 'split/chained' ones loaded in at the same time.

This is where the backers can have a say: since these are factory presets, what splits/chains do YOU want to see? There is a detailed PDF of every effect and how every CV/button is used on the E520 product page on the SynthTech website. We encourage everyone to download and look this over, then think about what makes sense and then HOW the CVs/buttons are re-assigned. It's a daunting task, even for us.

If we get little input, you will (initially at least) be "stuck" with what the design/beta team decides. So, please ponder this and tell us what YOU think is a good combo.

Thanks again for hitting #2, and here's hoping for hitting the remaining 2 as time start to run out. Spread the word!

We re-wrote the Looper algorithm from scratch. Added variable 4th order tape saturation, some feedback EQ, pitch shifters, reversing without 'pops' or 'clicks', and a 'Degrade' mode.

Full notes on the soundcloud page.

Is it possible to have some sort of Spectral Morphing between two different sounds?

New E520 Hyperion Effects Processor demo, featuring the newly re-vamped Spectral Time Machine algorithm.

1 week left on the KickStarter campaign:

Around the 0:58 mark, the 'Spectral Feedback' is applied, and then the recording eventually dissolves into primordial swamp goo.

Just backed this project while not being a big fan of Kickstarter. I'd rather wait until the finished product is available but in this case I just hope the project reaches "Stretch Goal #3 - $105,000: Spectral Drone Machine algorithm. Creates an ambient drone from a small time sample of incoming audio."

Spectral Drone Machine just sounds like such an awesome idea, especially for a fan of drones like myself.

3 days to go!
