Klanghelm TENS v1.1.2 WiN macOS RETAiL-ohsie screenshot

TENS has been physically modeled after the range of high end studio spring reverberation units introduced by a famous Austrian company from the early 1970s to early 1980s. As opposed to classic spring reverbs found in guitar amps, these units were based on the company's own patented proprietary design principle, which allowed various connected spring elements of different lengths and wire diameter to vibrate inside a small isolated space. The spring elements were manipulated in various ways, e.g. by etching the wire surface and deforming individual turns of the coil wire resulting in a highly diffused, and very dense reverb, that didn't expose the boing/chirping artifacts associated with spring reverbs and brought it much closer to the sound of plate reverbs. This range of reverbs is praised for its incredibly deep, organic, complex, rich, smooth and floating character. In terms of sound (but of course not technically) it can been seen as the missing link between classic spring and plate reverbs. A very unique beast indeed!

To extend the sonic possibilities of the originals, TENS offers:

- a wide range of decay times (from 0.2 seconds up to 40 seconds)
- as opposed to the original each tank of TENS' models outputs a stereo signal instead of mono
- various options to deeply alter the actual models via the TENSION, WHOOSH and METALLIC controls
- optional (pre-)amp saturation, that can be placed freely in the signal chain
- three modulation slots to add movement or create out-of-this-world sounds
- every continuous TENS parameter can be a modulation target
- the target can be modulated by either an LFO or envelope follower
- the envelope follower can be triggered by either the reverb input, ouput or even an external sidechain signal
- using the envelope follower for ducking effects is also possible
- the envelope follower can be used to shape the dynamics of the input, the optional amp saturation and the reverb signal
- with the modulation section various modulation effects can be achieved, such as tremolo, chorus, vibrato, phaser-like sounds and more rather unusual sounds plus combinations of the aforementioned effects

Brief history of the units, TENS was modelled after\
It all started in 1972 with the release of the BX20. With the size of a fridge it still had a much smaller footprint than the available plate reverbs at that time.\
In 1975 the BX10 followed. It was designed to be a portable version, where the carry handle could be used to lock the tanks for transport. It had a much smaller footprint than its predecessor.\
By the end of the 1970s the 3u rackmount version BX5 has been released. It was the most affordable model of the BX line.\
1982 saw the release of the BX25 model. This incarnation of the BX range managed to increase the spring length by about 20%, while reducing the enclosure size by about 60% compared to the BX20 model. the BX25 included an inbuilt delay, which was intended to be used as a pre-delay for the reverb. The BX15 had been released the same year. It was built upon the BX10, and offered more selectable decay times and stepped controls for the EQ section of the unit.

TENS is available in the following formats (all included in a single license):\
Windows 8 or higher (64bit): VST, VST3, AAX Native for ProTools® 11 or higher\
macOS 10.11 or higher: AU, VST, VST3, AAX Native for ProTools® 11 or higher

Klanghelm plugins sound awesome, look great with perfect functionality, have no copy protection and are all less than 25 bucks each. Support for Tony is a given. I bought them all with pleasure and use his free ones too. I haven't yet tried this reverb out yet but I'm betting that it is fantastic. I was hoping he'd do a verb and now I'm stoked to check it out!

quote by tzzsmkWhat kind of copy-protection is used by Klanghelm plugins?

"None. I hate copy protection. I've suffered from it in the past. I've lost countless hours because of copy protection. I believe copy protection only punishes the honest customers, because the software gets cracked anyway. I simply refuse to waste my resources on copy protection schemes. Instead, I want to spend my time supporting existing products, improving them and developing new plugins.

I believe in a world of trust and copy protection has got nothing to do with that."

That's the reason why I will stay miles away from devs like Acustica, who choose to protect their business at the expense of their loyal customers, and persist in being ridiculed by a team of talented crackers (which not only destroy their protections, but also correct their errors) rather than devote resources to improve the terrible workflow of their products.

Tony is a master compared to Junkarlo. Another class. Another league.

Yep, instant buy! Great dev are supported.

sounds really good, featured all the famous BX series. Minimal tweaking option, not over the top, just nice. Not really CPU friendly, so I just did a CPU comparison with any reverb plugins I have that comes to mind randomly and keep it for my record but I thought just share it here, maybe it could be some use to others.

It makes no sense to say you’re not good at it. It’s like saying, “I’m not good at being a monk.” You are either living as a monk or you’re not.

Yeah i thou8ght that too, nice but too much cpu
  Resident 27.02.2022 404
Write also your CPU - Motherboard - Audio Interface - DAW etc specs to compare with ours .

For example TENS on my old xtreme CPU at 48khz 64 bs gives me 16% but ....... Kush Audio Goldplate ( best plate for me ) at 48khz 64 bs gives me ,,,,,,,,,,,,,,, 65% with oversampling off !!!!!!!! lol ( Ableton Live )
  Member 29.11.2020 29 2512
my bad that one was with OS off, with OS on it's still the King of All CPU Hog Reverb plugin. 38%! Im on Ryzen 7 Octacore 16GB WIN 11. Pretty old spec too.

quote by Stevie Dude9) Valhalla VintageVerb - 0.5%
8) AudioEase Altiverb - 1%

13x Altiverb? That's ridiculous.

"UVI Plate - 3%".
Did you tried with the highest "insane" settings?

"Plate’s performance is based on the number of modes,
and uses an intelligent mode pruning algorithm that
keeps the most important modes in order to achieve
the best sound quality for a given CPU budget.
A mode is a voice of reverberation similar to the polyphony of
a synthesizer. Unlike synthesizers, Plate’s polyphony ranges
from 3,000 voices at “Low” to 20,000 at “Insane”.".

I doubt it would give a 3% on CPU in "insane" mode but anyway, these tests need more info, hardware info, OS info, DAW and audio interface info.

main purpose was to roughly give an idea where the TENS at among them, whether to the high side or the low side. never even intended for the accurate result.

I see, but can you tell me the hardware specs of your machine?
  Member 12.08.2021 122 2
he already did, above
  Member 12.08.2021 122 2
TENS have 2 tanks. Activating only A tank use half CPU.
  Member 20.11.2023 40
One of the rare plugin makers that has made windows 7 incompatible plugin. This is sad because klanghelm is pretty decent

Usually its some unnecessary gui thing

Why you still on WIN7 whats the point when new versions are faster and better ?

Anything below that garbo Win11 and above Win7 is fine for me. Oh no. We are only left with Win10 prolly! :D

Izotope how to get light reverb exponential audio and transform it in heavy CPU reverb
for spring , 13% it's to much, will prefer the eventide spring even if it requests CPU , but in light CPU the overloud springage or impulse altiverb and average CPU PSP or U he

Even if we get better CPU since 2000's Dev spend less and less time on CPU usage. This is why i still use the lexicon PCM so light but even those who use 10* more CPU don't sound as good. And they mostly stop the support like exponential audio R4 or nimbus, so no problem to use the version of the great R2R
But cinematic room liquidsonic very light on CPU and sound better than most of the list upper, In big session it's important to get VST well dev
  Resident 27.02.2022 404
The funny thing is that Klanghelms Spring is fuckin awesome ! Maybe the best Spring Reverb in my ears together with another CPU killer Physical Audios Dual Spring Reverb . Havent tested it for a long time but first impression is outstanding . Overlouds is also interesting and light . High CPU usage doesnt mean high quality but most of times means bad code . Also many Devs think that we will feed a hardware synth and play live ....... they dont care as long as they make money .....
  Member 8.11.2023 14
yes sound good (aegean got one good too), but most of the time spring reverb still for instruments like guitar ,... not the main reverb so in big mix session will not waste my CPU for a reverb with a small gain when a much lighter will do the job. the CPU still important in my VST choice
  Resident 14.05.2017 553
"I'm over at @ bleen 's studio today, doing some reverb work. We put TENS on just to give it a listen. Sounds SPECTACULAR. I'm super impressed with both the spoing-y-ness of it (physical modeling right there!) and the overall smooth sound. Love it on drums. The different modes all sound great. Really captures that BX sound, where it has that spring sound while overall being much closer to a plate reverb (and a well tuned plate reverb at that). Nice work!".

Sean Costello, ValhallaDSP.

"Wow. Thank you so much. This was totally unexpected. And being a fan of your work, it's super appreciated."

If there were more kind people like that... I'm not even going to try it, I'm going to buy it straight away.
  Member 22.10.2021 252
Thank you @Stevie Dude for your comparison of reverb CPU hogs for everyone to see. One other useful thing next time would be to add how large each reverb plugin is also. Maybe large sized plugins are the source of the problem. just a theory. Thumbs up to all plugin programmers, coders who know how to properly modular code, keeping file size low, cough cough Acustica Audio.
