Eplex7 DSP Klerphonik – polyphonic analog synthesizer

VST plugin with virtual circuit emulation technology +
world’s first time capsule technology


After the great success of the Klerhaim monophonic synthesizer, that many users described as one of the most authentic emulations on the market. We received many requests to produce a polyphonic synthesizer. We set to work hard and using our 17+ years of experience and virtual analog circuits technology and we developed another analog synthesizer.

Now we are introducing Klerphonik, polyphonic VST analog-emulated synthesizer, a brand new plugin instrument with world’s first time capsule technology.

No, Klerphonik is not only extended version / polyphonic version of Klerhaim N1! It is a brand new synthesizer with a completely different sound, color and extended options.

Klerphonik’s sound is different – more dynamic, more musical, subtle, more organic, colorful in the mids and highs, less bold and less saturated than Klerhaim N1.

However, Klerphonik is still very analog, dirty, colored and spontaneous.

Thanks to analog circuit emulations is its sound constantly alive and ever-evolving. If you are looking for a organic analog sound, the opposite of digital sterility, try the demo version.

It’s definitely not enough to listen to our youtube previews – youtube trims highs, screen-capturing reduces quality, streaming data compression enhances quality, and trims analog mojo.

It is necessary to try the demo version for your own experience!

SONG “Dirty girl” by Anders Analog – made with using Klerphonik synthesizer. It’s an 80s synthwave electropop track and the Klerphonik is doing the bassline and the high pitched continuous chords.



A world novelty are the so-called time-slot capsules and init presets. What is it?

As you probably know in case of real analog synthesizers, it can happen that the same model sounds different not only piece by piece, but for example a 30-year synthesizer sounds different from the same model made a year ago. It is because many electronic components age / grow old and change their sound.

Thanks to time-slots, you have at your disposal like 6 different-sounding synthesizers in one! Thus, a wide range of sound colors. As different age or brand of used components such as resistors, capacitors, transistors, transformers affect the sound, the time-slot capsules do the same. Each time-capsule sounds differently, each has a different overall sound color, mid / treble color, different saturation level, boldness of sound, amount of higher harmonics, analog de-tuning etc.

Another specialty is the 4D Dimension analog chorus / flanger and a 14-bit digital vintage stereo expander which sounds completely different from regular choruses. The digital 14-bit stereo expander, modeled on 80’s devices, will also deliver original sound from early digital records and a very unique color / type of sound.


In the plugin development we have used our long-term experiences with digital sound processing and education in analog electronics. See video from Eplex7 analog laboratory.  

What is Virtual analog circuit technology?

“Basic code cannot behave like electricity in real analog circuits. That is the reason why we developed our own virtual circuit technology. We are emulating whole analog circuits, electronic components and modules of synthesizer + their behavior in various situations, noises, feedback, interfering signals etc”.

This technology was used also in our monophonic synthesizer Klerhaim N1 and Vintage Vacuum Tube VD76.

See video for better understanding the difference between digital and real analog synthesizer.

In real analog synthesizer everything is moving, changing, modulating, living… analog synth is like living organism, nothing is static, electricity and circuits are in constant “chaos”. Analog oscillator waveforms are not precise, sharp and always the same like in digital synths – they are changing their shape, has noise, harmonics, ringing, modulating their tone / pitch, volume etc. Also output from oscillator module is saturated – not just output of whole synthesizer but output of every circuit / module – more volume of oscillator = more saturation and color. Analog envelopes (modulating filter, amp or pitch) are not linear like in digital synths. They are exponential and they are changing their shape in time / different with every different note. Include some noise and harmonics too, peaks / spikes are not digitally sharp but analogue round. Filters are creating small distortion / harmonics, they are not perfectly stable, values are changing 0,1%, include noise, output is saturated.

Simply everything is “living” in analog synthesizer because of laws of physics / electricity. Every note sounds little bit different, that is why analog sound rich, organic, warm, fat and like real instrument. We successfully emulated analog behavior, individual circuits and electronic components.



from independent producers

“Great synthesizer, sounds amazing. I love the fact it is polyphonic!”

(ericbridenbaker, Gearspace member since 2011)

“It’s a really good synth, powerful with a lot of life and movement. Sounds almost like hardware. Glad I bought it 🙂 Hoping you’ll make more of these non-linear, sweetly saturating analog synth emulations in the future.”

(Anders Analog, Eplex7 customer)

“You’re right, you need to download the demo version, not just listen to youtube, which reduces the sound quality and removes the magic. This synthesizer has a lot of analog magic.”

(Krenkrawler, Eplex7 customer)

“I think this sounds great! Every time I listen to the YouTube video, I catch myself thinking: they recorded real analog synths.”

(TonStrom, Gearspace member since 2010)

“…I’ve had it for quite a while, along with the kick drum synth which is also awesome.”

(Soul2Sound, Gearspace member)

“You’re doing a great job with these dirty analog bois don’t stop!!”

(Maciollo, Eplex7 customer)

“This thing is ridiculously good and surprisingly flexible. The way the filter opens up is incredibly real and super rich. Great job Eplex! I’m buying it right now.”

(ChocolateHawkins, Gearspace member since 2016)

“Thank you again and for the really nice sounding products Klerphonik and Klerhaim N1 made by Eplex7!”

(Luis, Eplex7 customer)

“If you need constantly evolving, organic, living rich analog vst synths check this out! … far from sterile, boring wannabe “analog” vst emulations…”

(Dennis, Eplex7 customer)

“It sounds a completely different and has unique color!”

(Andrew B., Eplex7 customer)

“…thanks for making these synths- Klerphonik and Klerhaim; they do sound amazing.”

(Dan, Eplex7 customer)

“Great sound, looks so easy to use which is cool.”

(Sirwan music at YouTube)

“I like it very much. Very ” fat ” sounds !”

(Greg T., Eplex7 customer)
