Eurorack Modular

Pailo Nebulae Sound Pack 1

So i recently made a sound pack for the Nebulae Eurorack module by Qu-Bit Electronics. After downloading the new software, I notice how great it pitch tracks waveforms while freezing the sample. This made me think about how cool the module was, and also made me want to make it cooler for other users out there in the eurorack world.

This pack includes samples from the
buchla 200 skylab, the octatrack by elektron, an 18u eurorack modular, and a Tama roakcstar mahogany drum set. They were cut down in Ableton Live and converted to mono at 44.1khz 16bit. It loads extremely fast on my unit at home, so remember the sound pack has be tested to work before uploading to the downloads page. I wanted it to be easy for all users.

In this pack there are some loops, one-shots, phrases, and other sections of music from some of my last recordings. They are recorded through a Radial Workhorse 500 series rack with PreComps, and PreEQs by radial. The signal chain then went through a RME Fireface 800 into a QuadCore Mac Mini. It took a few days to collect the samples and then convert them to a correct format for the module. If you are trying to make your own sound pack and have not had luck, remember to convert the files to 44.1khz 16bit MONO for the easiest results. I tried doing higher sample rated things, but it never seemed to load all the files the way i wanted them to sound.

If you have any problems loading the packs let me know, and i can also help you upload your firmware if you are having problems.

Sonic Potions DIY

So here are some shots of the Sonic Potions build. A few tips would be,

1. Start in a well lit area with plenty of table space.
2. Have a solder sucker, wire braid available in case.
3. Take your time and follow all instructions.
4. Have needle nose pliers, and sharp snips.
5. DO NOT USE the only 200ohm Resistor. Change it to 10k.
6. Choose any an ultra Brite LED color instead.
7. The LED mod allows the GATE OUTPUT JACK to truly send 5volts.
8. Enjoy the build pictures posted below....

Dee Box Prototype

So the Dee Box project began a little while ago. Sat down with a really great wood designer (Dee) who inspired me with his amazing home (made of wood) which of course went on to us talking about synthesizer cases. I told him what I had in mind and we sat down and drew a few ideas.

This box is just a starting point for me and Dee working on projects together and I want to show you what went down and how I powered the box with help from DIY boards. Lets take a look at what happened…

DeeBox Front

Here is the first public shot of the Dee Box. I wanted something completely original with this design. Planked out lid and back, with a bug eaten handle (Dee’s amazing work). This case is made for laying down at a table when you are performing. The cables hang on the handle while you perform.

DeeBox Inside Pre Fill

This is a shot of the inside of the box prior to putting the voltage regulators inside. If you look at my past BLOGs you will see that I have a separate box for my power supply so no supply is needed in the back of the case. Simple Vector TS204s are used to mount the modules.

4ms Regulator Boards

Above are the 4ms regulator boards. These basically take 15 volts and convert it down to 12 volts. Each 104hp has 2 boards giving about 2.2 Amps through of power if needed. The supply is running close to 7A @ 15 volts. Should be enough power for about 6 rows in my opinion.

4MS Finished Regulator Board

The finished regulator board before I cut the leads off above.

Panel Mounting Regulator Board

Panel Mounting Regulator 2

This is where the Power Din Module is connected to the regulator boards. Basically you have to solder the wire +15V, -15V, Ground and 5V from the regulator board to the DIN input module. This takes some patience.

Then the DIN Panels are installed along with the Regulator boards inside of each row. This was done with a few small 1/4” wood screws. As you can see the wiring is done with quick release connectors so anything can be disconnected and moved or worked on in case of any changes.

DeeBox w Modular

Here is the final case filled with half LZX and half of audio modules. This is a perfect example of a DIY case with the 4ms Regulator Boards. A big thanks to Dee Church, Dan Green and all of my friends who helped me connect with all of these great people.

6.7A Power Supply Build

I documented my power supply build so everyone can see how it happened. You will see in the first step there is a plastic case with two supplies. Each one is 6.7A and they are going to be wired together to create a +15V/-15V power supply. The mounting is done with 1-1/4” 4/40 screws, washers and lock washers. There are also two 1/4” 4/40 plastic spacers so the power supply bottoms and plastic case do not touch in case of supply heat against the plastic case.


After that I trace out the MIDI/DIN jacks on the side of the plastic box before cutting each one out with an Exacto Knife. They are super sharp and can cut holes out really close. Be careful though, one wrong move….ouch!!!


Once the MIDI/DIN holes are cut I moved onto the IEC jack with fuse holder. That cut was also done with my Exacto Knife to get it as close to the size as possible. This also helps with the midi jacks because you can have enough plastic to screw them in with 2.5mm screws and square nuts. The IEC also has tabs so if the hole is the correct size it locks into the plastic and stays put when plugging and unplugging.

Next is cutting all of the wire to size and putting Female Terminal Connects on all of the wire going to the IEC jack and stripping the wire to be on the supplies and soldered to the MIDI jacks. This step is the most important because the ground wire in my box is done with 12G wire and all of the power if done with 16G. From doing car audio we always used thicker wire with the ground. The shorter the run of cable the better so there isn’t a bunch of wire in a corner of the box. It could also cause EMI noise in your audio lines.



Once the wiring is done and the MIDI jacks are wired and soldered I go get a multimeter and test all of the jacks to make sure the power is giving +15V where needed and -15V where needed. There is a regulator board inside each of my cases that regulate the boards to +12 /-12. Running the system this way has been documented on the ELBY Designs site. It seems to be solid. If you do not know about voltage regulators you can always buy +12/-12 supplies and just go straight 12volts.

You can see my power MIDI/DIN jacks are finished. Then i GOO-Gone the marker off. Please note that people in your studio SHOULD know there is power running on MIDI/DIN jacks. If one of these gets plugged into any gear you could have a total gear meltdown. My studio speed has become much slower now that there is power running along MIDI lines. Be CAREFUL if you choose to run things this way. MIDI jacks have plenty of pins and usually are handy for running over 10’ lengths for connecting gear/power/audio in certain situations.


My final wiring is below. As you can tell I like clean wiring and simple design. I found the plastic case in the trash and the supplies were 30$ each online ( Wiring is about 5$ with a 3$ IEC plug and 1$ fuse. Pretty simple project that took me about 1 hour.


Case is powered and making amazing sounds!

Mattson SQ816 Looks amazing! So many variables, with tons of details mapped out on the Division 6 website. Nice to see more sequencers out.


Weekend Fun

Been working on a new module for myself which is teaching me the ins and outs of op-amps. It was hard to get a grasp of what to even start with but things are actually coming along. TL072 is the beginning of my journey.


MC303 Acid Labs

For 420$ is it worth it? Looks nice and OSC and Filter w ENV in one module. The sequencer is 499$ so for about 1000$ you can have a eurorack tb303. Seems like a cool idea. The sequencer has gotten good reviews to in the clean function, and real time step programming. The quality of their gear is top notch but how many of these are there? I just like the design here.

Eurorack Community

We try and follow all of the new Eurorack modules that come out but there are over 700! This BLOG is where I generally talk about items I want for my case, or things that I already own and just want to say how much they work for me. Keep tuned in for Sound Modular updates and OutoftheBag information too.


Last night was filled with deep bass, and crazy pulses from the Cyclebox. An amazing Eurorack Oscillator that has plenty of wavetables and sounds to keep you tweaking for days. Pitch tracking is awesome and you can get some very vocalist tones, sub bass, piercing high notes and leads forever.

Highly recommend this piece for your case.




The new sequencer I have been eyeing up….. Looks really cool. Only found it in Germany though… boys @ schneiders rock. Share all my secrets here.

Busy Working

Designing cases is a ton of work. Now that we have some really nice designs i need to figure out what people would really want. I love this new case, and the music that has been coming out of it is insane. The sound cloud account has some new tracks up. Check them out.

2row Wood

So Jared and I built this crazy case. I wanted a pinball machine. Crazy. Not completely filled yet but its getting there. Have the Optomix from Make Noise on the way.

Sound Modular is working on this new wood line. We have some great ideas. This is going to be a productive year in building cases, and getting people excited about modular synths. This is the best instrument i have ever made in my life. Can not wait until the 10 row!!! Pictures are below.
