The River JX-3P MIDI expansion kit, originally sold under the name Organix, found its way into numerous classic Roland JX-3Ps. It was a joy to receive so many kind words and compliments on the kit from JX-3P owners around the world. Despite this, the time has come to discontinue the expansion kit. We hope our efforts have kept the classic JX-3P alive in the modern world, and will attempt to continue technical support for owners of the expansion kit.
The latest River news
Dear synth lovers,
It was truly rewarding to receive so many positive reactions to the Eurorack designs I’ve made over the last few years. As a big thank you (and in memory of two of my dearest synth heroes), here’s a special offer, valid until the end of the year:
Coupon #1: BOBSURUNCLE – Free shipping on all Eurorack orders
Coupon #2: KEITHROCKS – 10% discount on all Eurorack orders
Happy modular 2019!
Dear JX-3P lovers,
After receiving many encouraging emails (thank you!), Laurens and I decided to do another production run of the JX-3P MIDI expansion kit. The new batch arrived right on time for Christmas and can be ordered directly from stock. If you decide to order or already own the expansion, be sure to check out the wealth of resources in the side-bar of the product page. Over the years, many wonderful initiatives popped up around our expansion for the JX-3P, making it easy to edit from Ableton Live, iPad, a VST-capable DAW, and modern hardware.
I’m happy to announce two new fruits of this year’s creativity:
Marble – Dual spectral tilt tone control
Dendrites – A multicharacter multimode VCF / phaser
Both modules can now be ordered, and first units will be shipping on February 1st, 2018.
I wish you a very happy and musical 2018!
I’m happy to announce the result of a fruitful collaboration. This time it’s not a Eurorack module, but a MIDI expansion kit for the Roland JX-3P synthesizer. With some tender loving care, it brings the JX-3P’s MIDI capabilities up to modern standards.
- real-time control over all JX-3P parameters with standard MIDI CC messages (from a sequencer or MIDI controller)
- velocity sensitivity (via MIDI)
- selectable MIDI receive channel (1-3)
- loading new patches into the JX-3P via MIDI
And for PG-200 owners:
- simultaneous control via MIDI input and PG-200
- transmission of MIDI CC messages from PG-200, for recording in sequencer, or controlling other MIDI devices
The expansion kit can now be pre-ordered here, and first units will be shipped in october.
In the fall of 2016 I was approached by Markus Völter to do an interview on synthesizers for his Omega Tau PodCast station. The PodCast shows normally contain in-depth interviews on science and technology, but for this interview we stretched it all the way from science to art. We took an entire morning and part of the afternoon in my studio to talk and play examples on different instruments. Markus even turned our vocoding efforts into an Omega Tau jingle!
You can listen to the complete interview here: http://omegataupodcast.net/237-synthesizers/
But there’s more! As a former scientist I really admire how Omega Tau makes these long in-depth topics accessible in a pleasant way to a wide audience. It is driven by sheer enthusiasm for the topics on show, and many unpaid hours are put into it. I’d like to support that, so I decided to give away one free Eurorack module: one River Crux dual VCA + free shipping to anywhere in the world. A winner will be randomly drawn from those of you who listen to the interview and answer the following question:
“What type of MiniMoog does Rutger have in his studio?”
Send your answer to me before june 1st

I’ve been invited for a presentation at FAQLab 2017, January 7 starting at 14.00, location: Toonzaal, Den Bosch. I’ll use the occasion to talk about how River Eurorack modules are made, and give a sneak preview of two new upcoming modules!
On Saturday the 2nd of April I’m organizing a course in synthesizer techniques and sound design (in Dutch), location: Nijmegen. Read more about it, and subscribe here: https://riversynths.com/synthworkshop
The camera has been running hot! Here’s a demo video of the new Nucleus filter.
In the workshop section you’ll find video’s of how the Crux and Nucleus modules are made from a DIY kit. Documents with detailed DIY instructions for the kits can now be found on the Crux and Nucleus product pages.
Hi! It’s been a very hectic, but encouraging end of the year. Months of hard work have been brought together last couple of weeks into the release of the first two River Eurorack synthesizer modules: the Crux VCA and the Nucleus VCF.
