Creating Lush Reverbs and More with Bopp and Steve Video by @RaafModular

The Bopp & Steve Deconstructed Reverb by This is Not Rocket Science (TiNRS) has been on my radar ever since it was first teased at Superbooth Berlin a few years ago. With its unique approach to reverb and its unconventional interface, it immediately stood out among the sea of more traditional effects modules.

Earlier this year, TiNRS finally unveiled the finished version, and it’s been making waves in the modular community ever since. You may have already come across excellent deep-dives by DivKid and SonicState, both highlighting its creative potential and playful sound design possibilities.

But today, a new perspective caught my attention — a fresh video by Dutch modular artist Raaf Modular just popped up in my feed. 

He’s relatively new to creating content, but his style feels personal, musical, and refreshingly unpolished in the best way. 

It’s always exciting to see these modules in the hands of musicians who approach them from a purely creative angle rather than just technical.

Definitely worth checking out — and while you’re at it, give Raaf Modular a follow on your favorite social platforms. Support your local modular heroes!

"This is a new kind of video for me.

In this one, I’m focusing on a single module — BOPP and STEVE by This Is Not Rocket Science.
This is not a review. I’m not a reviewer — I’m a musician. (plus a teacher! (red))

So rather than diving into every technical detail, I’m giving you a musical demonstration: how I use this module to patch, play, and make music. 

It’s a new direction I’m exploring, and I’m really enjoying it.
I originally started this channel to share my music, but more and more people have been asking how I create it — how I patch, how I build my sounds, and how I work with modular gear.
So this is the first step in sharing more of that side of my process.
Let me know in the comments if this kind of video speaks to you — 

I’d love your feedback. Thanks for watching

ErrorInstruments Kharper EuroRack Electronic Harp

Two weeks ago, Paul Tas from ErrorInstruments released the Kharper Eurorack Module, built in collaboration with This Is Not Rocket Science (TiNRS)

The "Kharper -emuharphonica- Eurorack" is a kind of electronic harp, with 4 touch - and position- sensitive 'strings' on the frontplate of the module.

Every string is a voice. The strings are built out of two touch strips with an LED bar in the middle, showing you what kHarper is doing. 

Each string has a knob on top to set the tone and a CV -in below. You can also patch in a gate to pluck the string

Inside is a microprocessor that uses Virtual Modelling models to recreate different versions of the Karplus-Strong algorithm.

The Karplus-Strong algorithm, also called Karplus-Strong string synthesis, is a way to make sounds that are like plucked or hit strings, and even drum sounds too. It was created in 1983 by Kevin Karplus and Alex Strong. The method uses a short sound loop with a filter to repeat a small sound wave, which helps create a string sound that feels real.

I was already intrigued by the first demo's I saw earlier this year, and so far I love the sounds that i've heard of it from several sources that were lucky to get one from the first batch...

A wide range of sounds and soundscapes can be created, from spacey piano-like and harpy sounds.

It can also make percussive African drum-like sounds and even much more extremer noises...  ultimately you can push this module even leading to clipping, with cut-offs and distorted noises that even don't seem to belong there... the interesting area where even the calculations become unpredictable... lol

The Kharper is a 18HP wide skiff-friendly Eurorack module, but it can work as a stand-alone version too, powered by the USB connector on the back.

Via this connector you will also be able to download new sounds, algorithms, or even full alternative firmware. " In the future, there could be: • Traditional octave tracking • Different quantization schemes • Ambient or generative patches Or more experimental warm or noisy • New forms of sound design — all possible through open-source updates"

The Kharper comes with 9 (3x3), already impressive sounding models but in the future certainly different models will be downloadable.

INPUTS:

- MIDI in
- STRUM is a gate in that will strum all four strings
- Pond/River/Ocean - choice of sound engine
- Herring/Koikarp/Dolphin - choice of sound engine

The Tone and Decay of the selected sound engine can be tweaked with a knob or via CV.
All strings have a knob and CV in for tone and a trigger gate input to pluck the string see demo

OUTPUTS:  

- Control output Gate and CV

- Left/Right audio output

The first batch is already sold out
The kHarper will be available again in September.
