I build a few of these. When I was working with a Windows machine I could just use one of them. On a Mac I can use all of them. They are for intergration of de DAW with my rack. But since I bought a ES-9 I hardly use them anymore.

Building: The Thomas Henry Mega Percussion Synth (MPS)

Oh boy oh boy. This one is very special to me. I was in a bad period in my life when I started reading the Noise Generator Cookbook by Thomas Henry. Reading it gave me a lot of rest and I learned a lot from it. I didn’t know that much about noise, white, pink, red, blue and the noise in my head, it all started clearing up. In this book Thomas Henry writes about the Mega Percussion Synth (MPS). Back in those days a lot of schematics where based upon 15volt. I always wanted to have a MPS but never found the time and skill to transfer his design to eurorack (12 volts)

Then Haraldswerk released the MPS, and put the gerbers online for building one. Sadly it was still 15 volts and with banana jack. Not typical for eurorack. I wrote about this in the topic Haraldswerk posted on modwiggler. And I wasn’t the only one hoping for a 12 volt version with 3,5 jacks. That started a discussion and.. well

Some site updates

I found a way to remove all those post about the modules in my rack from the frontpage. I think I have most of them written now. I might need to update a few of them while playing with the modules more and more. I thought the frontpage got a bit messy with all those post so glad to found a way of removing them. Next up all the panel files I made and adding them to the website. After that maybe record some sound samples. Maintaining a website does take some time but I still enjoy doing it.

Erica Synths VCO

I just finished building the VCO and did a little bit of testing on it. I might update this post when I have used it a bit more. But first impressions it sounds really good. I like the FM and pulse input and have been playing with those CV inputs and lfo’s a bit and can imagine I would use this in some patches.

Building: Erica Synths VCO.

I have a love and hate relation with Erica Synths DIY modules. Some are quite nice to build but most of them are just terrible to build. I makes me wonder why Erica has left the DIY scene. I’m glad the put the designs on GitHub for the modules that they call legacy DIY. But I think the support desk was just overloaded cause these modules are just a pain in the butt to solder and are prone to make mistakes on. I had the VCO in my drawers for awhile and it was time to build it.

Quinie LittleBen

Another one of my own designs. I was in need for a master clock that would display the BPM and could be adjusted with a knob. There aren’t that many out there that fitted my needs. So I made Littleben. It started out as a simple clock with 4 clock outs and 4 reset outs. Running on a Arduino mini the firmware grew and now it can do a lot more. It can divide clock, calculate a incomming clock and I’m still not finished in releasing firmware for it. I have plan for more functions. If you want to know more be sure to check out the menu on Littleben. If you want to build your own you can find it in my shop.

Quinie NanoGris

open for offers on build modules

Another one of my own designs. The original design is made by Mutable Instruments and called Grids. It’s a drum trigger sequencer. When starting into eurorack I started out with a lot of drum modules. But had nothing to trigger them. I designed the Nanogris of the Grids schematics but used all thruhole parts and a Arduino Nano. It was quite the journey. I did some pcb’s design before but this took a while to get right. And even when I got it right I still could do somethings better. The Nanogrids is now on version .041 and I think I got all things correct now. More info about this module on this site (see menu) and of course if you want to build your own it’s on GitHub and in the shop

Quinie Hagiwo Quantizer

Well I can write a lot about this module, but I already did on different parts and topic on this site. I made this module myself based on Hagiwo design. Used his schematic, changed the DAC chip to a thru-hole type and made pcb’s and panel for it. It’s a nice little quantizer with slide function. You can find more information on it on this website. If you want to build your own be sure to check out the shop. It’s fully open source if you want to make the pcb’s and panels yourself.

Weston Audio AD110

I started out my eurorack with drum modules. It was more a drum machine then a synth. But when the hexinverters clap failed to startup and the snare wasn’t what I tough it would be I started building other modules. But I found myself always looking for more drum sounds. The snare and clap where missing quite a long time from my setup until Weston released the AD110. This would surely fit my needs for a good clap and snare, and it did. The modules also comes with a bass drum, cymbal and hithat. It’s a all in one drum machine. Based on the Korg DDM-110. It has some modifications but sound oldskool and good. The manual is well documented.

Difficulty to build: Medium, some may find it hard. Has multiple pcb’s, can take up some time but well ordered and spaced

Neutron Sound Orgone Accumulator

I bought this module a few years back. It’s a great digital oscillator with a few trick up it sleeve. It has a Teensy on the back loaded with the firmware. I bought it when it was still made with thruhole parts nowaday it comes as a SMD version. I should still be possible to build by hand. If your looking for a new osccillator be sure to check this one out and not be fooled by being on the market for some time now.
