After weeks of searching for the "perfect" experimental oscillator for creating West coast synth sounds in my personal music music, I decided to make my own with modules that I already owned!
The WMD/SSF eurorack module line is perfect for this purpose as it is full of awesome bread and butter modules that are built well, sound great, and don't cost an arm and a leg. I used two Spectrum Oscillators, a Blender Mixer, and an Ultrafold wavefolder as my base for this concept, trying to make complex waveforms with wild results without the use of a filter.
Check out the video and hear it for yourself!
The Buchla 259 Complex Waveform Generator was a groundbreaking module in synthesis in the fact that we did not yet have the means to create digital wavetables out of algorithms. Instead, we had to use wavefolding and modulation techniques to create complex, never before seen or heard waveforms.
In this video, we explore methods of creating our own complex oscillator style synthesizer voice using the Eurorack modules we already had in our case. Though this is an explanation on how to use WMD and WMD/SSF modules to create a complex waveform generator, you can apply these same techniques using many different brands of modules, as long as they have the necessary features such as Frequency Modulation (FM) wave shaping or folding, and a VCA to perform amplitude modulation (AM) I could have gone deeper down the rabbit hole of AM and using different tunings for each oscillator but I got distracted by the sounds I was making with FM and wavefolding. Maybe that's a topic for another video?
West Coast synthesis is something that we don't explore much in WMD demo videos as we are constantly searching for ways to make melodies, basslines, and drum beats quickly and efficiently. When it comes to adding something a tonal, ambient textures and strange rhytmic loops, the complex waveform generator concept is an awesome way to add some discontinuty to music. The basic nature of the style of synthesis lends itself to creating complex and ever-changing waveforms as when two oscillators are used without syncing one to the other, differences in pitch and phase cause the signal to be less static than that of an rhythmically produced wavetable waveform.
This video was recorded live and then edited down to preserve the bits that we felt were most important to share. For more information on complex waveform generators and concepts, check out Learningmodular.com and the book, Patch and Tweak.
The WMD Geiger Counter is becoming a classic for guitar players seekeing the avant-garde distortion of their dreams. Digital conversion used to create screaming bitcrushed destruction and wavetable mapping for intense leads, it has been used on countless albums and stages by artists big and small.
What does it sound like on a synth though? Can you run a synthesizer straight into a guitar pedal? Does the WMD Geiger Counter sound cool on synths? What can I do to dirty up my vintage analogue synthesizers with distortion?
These are the questions we aimed to answer in the following video.
What's the best eurorack wavefolder module? How can I create raunchy, harmonically rich bass lines without a lowpass filter module? What is wave folding?
If you've asked these questions to yourself before, you'll want to check out our latest video showcasing the WMD/SSF Ultrafold eurorack module for modular synthesizer systems.
WMD/SSF is our line of modules that we collaborated on with Steady State Fate (SSF) a few years back. Built to the same rigorous standards of WMD modules, the WMD/SSF line includes 15 modules with straightforward user interfaces, simple feature sets, and dedicated purposes.
The Utlrafold is a wavefolder and distortion generating beast. Take a sine wave and turn it into a mangled, sonically rich lead with the simple turn of a knob. CV control over every parameter lets users control every aspect of their timbre with external sources.
THE WMD/SSF Ultrafold is an all analog wavefolding module that was made in a collaboration between two eurorack modular synthesizer companies WMD and Steady State Fate (SSF).
In this video we run a Sine Wave from the WMD PDO (phase displacement oscillator) into the Ultrafold and experiment with sounds along the way. Wave folding is a great way to create low-pass filter like sounds but starting with a sine wave and creating harmonics with modulation and wave mixing instead of using a filter to cut out frequencies from a harmonically rich wave.
A second sine wave from the PDO is inserted into Ultrafold's FDBK input, giving the module a secondary source for the wavefolders feedback path. When the feedback CV is positive this waveform is used. When this waveform's phase is modulated it will create even more interesting and dynamically rich harmonics.
In this patch we are simply using a sine wave oscillator, the ultrafold wave folder, a VCA/Envelope Combo and a trigger sequencer to drive the Envelope. The drums that come in later in the video are the HexInverter BD9 which is a kick drum, WMD Fracture and Chimera drum modules which take care of the electronic clap and tambourine sounds respectively.
The WMD/SSF Ultrafold is available now worldwide and comes included with the WMD/SSF Monolith system which is a euorack system integrated into a high-quality 37 Key keyboard case with integrated power.
Earlier today I had an idea. I wanted to use VOLT to control the influence input on Synchrodyne and use slow filter tracking so that any change I made on VOLT would be processed slow and have an evolving effect on the Synchrodyne's filter.
It worked out but was just too static for me. I quickly patched in a CV sequence and started to make a relatively melodic bass line with the Synchrodyne. I had a good time with this and needed some timbrel change so I added an envelope running through the VOLT into the influence of Synchrodyne. I quickly realized that this is what I was looking for. The VOLT became an offset for the envelope running into Synchodyne which basically made it an instant switch for the filter envelope's range.
After jamming this out a bit, I added a Spectrum Oscillator running the same pitch sequence through the Verbos Electronics Dual Four Pole filter. With a second Spectrum running the same sequence at a much higher octave, I modulated the filter cutoff on the low pass side of the filter. Then, with a very slow LFO coming from the ADSRVCA, I slowly modulated the same filter via the second input on the DFP. This created a sweet lead that matched the bassline but had a more smooth character.
Add some drums from the Hexinverter BD9 and Hihats modules along with the WMD Fracture and it was a party.
Mason, our programmer was working on a new module and accidentally made a crazy pitch envelope sound scream out of his headphones. His pain was my pleasure as it inspired me to make a crash out of the Chimera by setting the pitch env and decay at maximum and triggering it every 4 bars.
In short, this was a fun patch so I figured I would share.
To celebrate my favorite holiday I decided to take on Michael Jackson's Thriller, performing it using a Eurorack System. Of course, I had to perform it in my costume so here we have Thriller, performed by Randy "Macho Man" Savage using a eurorack system and a Juno-106 for the chords.
This was sequenced using the Squarp Pyramid sequencer and Expert Sleepers FH-1. I cheated a bit downloaded the MIDI fromfreemidi.organd arranged it to be played back via 3 main voices and an improvised drum track. The bassline is composed of two WMD/SSF Spectrum oscillators being summed and running into the Rossum Electro-Music Evolution filter. The Lead is all the WMD Synchrodyne with it's expand. Using the Synchrodyne for the lead voice gave the tune a unique flavor as it has a sound that is all it's own and even sounds a little "vocal" at times.
The pads were the Roland Juno-106 sequenced via MIDI from the Pyramid. The kick drum and hhats are samples being played on the Rossum Assimil8or and the rest of the drums were covered by the WMD Chimera and two Fractures.
The main performance aspect was controlling filter points, envelope lengths, as well as improvising the drums with the METRON sequencer and just being a goofball with some stage lights, lazers and too much fog. It was a fun, silly video to make.
Our newest module, VOLT, is set for release mid November.
Volt is a precision voltage source and offeset generator. Independent gate inputs for up and down control create a simple octave sequencer. Volt generates voltage in 1V increments with a range from -7V to +7V (14V range!).
This summer, we had the privilege of creating an interactive piece of art to be experienced at some local music festivals.
As the story goes, the WMD research team discovered strange, vibrantly colored crystals while exploring the planet Technosha 7. They harnessed the crystals’ resonant properties to create an instrument, one which allows humans to combine energy and intent as a group. Using its tactile playing surfaces, users are able to affect and guide the overall sound of the instrument, working in tandem to craft sounds ranging from atmospheric tones to dance music.
This piece was conceived for the Underground Music Showcase to reflect the power of community in the music scene, and to celebrate the passion that brings Denver musicians together. As an instrument, the Flux Interpolater can help bridge the creative gap between different skill levels, while encouraging improvisation and discovery as a group. Ideally, this will provide a way for our community of musicians and the general public to interact in a “hands-on” fashion.
The Flux Interpolator was featured on our local CBS 4 news. check out the feature here: https://denver.cbslocal.com/2018/07/27/underground-music-showcase-festival-ums/
We host an event on the second Monday of each month called Freq Boutique. It is held at a bar in Denver, Colorado called Fort Greene.
At the time of this post, we have just had our 17th event. It has grown substantially from a small group under 10 meeting up and sharing patch ideas in a performance setting to an event with a consistent attendance of 30-40 people.
Freq Boutique is run much like an open-mic for modular synthesizer performers. Each month, people sign-up online for a chance to play. A week in advance, we run the lottery and pick 6 performers and a set order at random.
We stream each event live and host recordings on our YouTube Channel. Check it out if you can't make it to an event in person!

When first getting into Eurorack, there are a ton of common questions with common answers. One of those questions is "where do I start?". This question is commonly answered with instructions and component lists for a "subtractive" synth voice, meaning an Oscillator, Filter, and VCA combo, and an envelope or two to control it. That paired with a sequencer of your choice and you're making Moog-like basslines in no time flat.
However, once you graduate to having more voices and sound sources in your system, it's likely that you'll want to get a bit more creative with your modules and use them for different purposes than you originally intended. This is important, as you can never learn too much, and trying new things keeps the experience fresh.
Filters have so much importance in the Eurorack system but don't necessarily need to to be a part of each voice. We all know there are plenty of ways to make awesome synth sounds without using a filter such as FM, PWM, PM, and wavefolding.
So, what do you do with your filters when you start experimenting with new synthesis techniques? Why would you want to buy another filter for your system if you already have one for each voice in your system or are using voices that don't need filters? Why are companies STILL making new filters? Aren't there enough on the market already!?
In this post, I am going to outline 3 ways to use the Aperture bandpass filter as a part of your patch, rather than a critical part of a single voice. These concepts can be used with any filter you'd like, but as the Aperture is a bit of an experimental module and was designed to be a part of a patch instead of a single voice, we are going to use it as our example.
1. Use the filter as a mixing tool.
Eurorack is an interesting classification of instrument as it requires so much more than just technical playing skills. When designing a system for music production style patches, mixing techniques are a necessary piece of the puzzle. While panning, level balancing, and compression are all becoming more important as our patches become more and more complex, so is the balance of frequencies we are using at once.
One thing that is missing in many Eurorack cases is the EQ. There are a few options out there but they take up room in the case and most are a sort of "set and forget" style of module that isn't Voltage Controlled. We have options though, we have filters! They can be used as mixing tools to help with muddiness and help mellow out high end harshness. After all, a filter is essentially a one or two band EQ. Use filters to help "place" instruments into a spot on the mix and cut frequencies that don't need to be present on certain instruments.
The WMD Aperture is a perfect module for this use as its high pass, and low pass filters can be controlled independently, either with CV or manual control. Use the high pass side to help free up low end for your bass line or kick drum. Use the low pass side to leave room for your high hats to shine
Below is an example of using the WMD Aperture as a mixing tool to place a full bodied drum loop being played with the Rossum Electro-Music Assimil8or into an existing drum beat made with heavy hitting drum modules.
2. Using a filter in the FX loop of Delay or Reverb for Dub like effects.
Many popular delays and reverbs in the pro audio and plugin world have built in filters for the FX loop. This has been popularized by reggae and dub artists and the technique has been used in countless techno, house, and ambient tracks as well. Not only does it sound cool, filtering your delay's FX loop can help your delayed signal sit in the mix while at the same time being more pronounced.
There are tons of Delays and Reverbs out there in the Eurorack format but few have built in filtering. Some of these have FX loops accessible with jacks so you can effect the wet signal with an external effect. This is a valuable place in a signal chain for a filter to live as it can help make the delayed signal sound more unique, dynamic, or simply better. Many digital delays generate exact copies of the signal so it literally sounds like you are playing the signal you are delaying over and over again. When using an effect like this with long feedbacks, it is super easy to over do it and have too much of one frequency be amplified in the delayed signal. This is especially true when using the delay as an AUX send and running multiple signals through it. Use a band pass filter like the WMD Aperture to isolate the frequency range you want to hear and cut the rest!
3. Using filters as submix bus and master bus effects.
Why choose to use filters on one piece of the puzzle when you can drastically change the overall sound of your tune by effecting the entire mix?
Running a filter on an aux send, behind a submixer, on the output stage of your entire can be a ton of fun and a cool way to add variety to your songs without changing any sequences or having to mute any channels. A stereo filter such as the Overseer will suit this application much better but if you are running a mono mix or have any mono sub mixes, toss a filter inline with the signal and experiment. Cutting bands such as the low end to give the audiences ears a rest is a super valuable tool used all of the time in electronic music production as well as in the DJ realm but this is eurorack :) Toss an LFO into the TILT function of the Overseer or the WIDTH function on the Aperture while effecting the drum mix or the master mix for some movement to the filtering.
