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!

Keeping a classic alive

Posted on Dec 16, 2018 by rutgervlek

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.

New year, new modules!

Dear synth lovers,

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!
