The Flux Interpolator at UMS and Temple Tantrum Posted on 1 Oct 00:00

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:

Freq Boutique newsletter sign up! Posted on 21 Aug 10:09

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!

Using Eurorack filters for more than subtractive synthesis. Posted on 7 Aug 11:26

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.

Creating a tiny Eurorack system for controlling and processing external hardware synthesizers Posted on 22 Jun 08:30

Eurorack is an exciting and enticing concept for many but the complexity and expensive cost of entry can be enough to turn many potential users away. There is also lots of confusion between what you can and can't do. Our advice to anyone trying to get into eurorack is see how it could fit into your existing setup, and just go for it!

Last week, I came upon an Arturia Microbrute and Drumbrute super cheap at a local synth swap. These little devices work really well together and are a great place to start with synths/drum machines. They're CV compatibility made me instantly want to make this system and in turn, this blog post and accompanying video.

One of my friends in the local synth community is interested in putting together a small eurorack system for processing his 303 acid boxes.  The dude loves acid music and is obsessed with the 303 909 combo.  I decided to make a little post and video inspired by him using the two new pieces of gear I had acquired.  

Using a bare bones set up I put together something that was a blast to play with and that had a bunch of options for interaction.  Had I spent more time, I probably could have made a bunch of videos with this set up, changing the routing and what controls what, but I had a blast doing what I did.

I learned that you don't need anything crazy to have some fun.  I scrounged two adapters to get the 1/8th inch signal into the interface and just used the headphone outputs of the MB and DB to get audio into the modular.  I didn't need any extra gain as the devices provided plenty, and no attenuation on my outs as the interface handled the signal beautifully.   The weird thing is that in the video, it looks like my volume is really low, but that's because I wasn't using the master output.  In fact, my HP out level was almost maxed as I liked the sound of the TRSHMSTR more when it was driven with a hot signal.

In this video, I created a small eurorack system made for processing external gear using the Doepfer Beauty case, the Shakmat Knight's Gallop, a WMD Aperture, and WMD Aperture.

I am clocking the Shakmat Knight's Gallop with the Clock out on the DrumBrute and then using the KG to create the triggers for the sequencer on the Microbrute. This way I can create interesting rhythmic sequences with only programming a few notes and change up the rhythm easily with the turn of a knob.

The Microbrute and Drumbrute are running into the TRSHMSTR and Aperture respectively (via their headphone outs!) and eventually I control the filter frequencies of each module with the CV outs on the Microbrute's patchbay. Though the Drumbrute has a built in filter, you cannot control it dynamically with the LFO or with CV. Also, the Aperture has a character that I love on drums due to it's variable bandwidth and feedback control.

The TRSHMSTR crushes the bass line and with a little help from the Microbrute's envelope CV output, it gets a nice and gnarly squelch pretty quick. Both of the modules are running directly into my audio interface via 1/8" to 1/4" adapters and 1/4" cables. This is fine to do as long as you aren't clipping the input of your interface or mixer. If you are having clipping issued due to high volume, add an attenuator.

If you have hardware synths that you love, are thinking about getting into eurorack but don't know where to start, try some processing! It's super fun and relatively easy to understand. Also, processing let's you start making music immediately with what you already have, which we here at WMD believe is the most important part. Make music and have fun doing it!

No talking in this video, just tunage and some complimentary text spelling out what happens as it happens.

Superbooth 2018 Wrap-up Posted on 24 May 14:12

Superbooth was a major success!  We had such a good time seeing everyone and met some incredible new friends as well.

It's such a cool feeling to be a part of something that is growing as fast as the synthesizer industry.  Superbooth has absolutely blown up in the past three years and we feel incredibly lucky to have been a part of it from the beginning.

Our newest module, Fracture, is a versatile percussion module with a wide range of sounds.  Aimed at making analog style claps, loose feeling hip-hop style samples, and even voltage controlled applause, it is a super fun module to work with.  It was great getting to show people what it can do and seeing everyone's positive responses.

The Eurorack industry as a whole is growing out of control.  The amount of new companies that show every year is staggering.  Another notable part of the Superbooth experience was the sheer amount of Eurorack and synthesizer users that come out.  We got to see some incredible performances that really inspired us to keep doing what we do.  Learning more about the way that people make music with this gear is such a rewarding thing.

Check this article out for gear that you might have missed

Alex gave a talk on the philosophy behind our newest modules as well as the WMD approach to making music within the modular.  He starts with a performance, then quickly runs through the feature set on the WMD Performance Mixer and our new Trigger Sequencer prototype.  The event was recorded so you can check it out for yourself right here!

WMD presentation @SUPERBOOTH18 from HerrSchneider on Vimeo.

We saw a ton of gear.  One of the standouts for us was the Schlappi Engineering Angle Grinder, a quad VCO with gnarly output.  I think we were all taken back by Eric's attitude.  He's one of the nicest guys ever but when it comes to his design philosophy, he designs stuff that makes the sounds he digs.  He doesn't really care if it's not everyone's thing, he knows that people align with his sound, he's just got to get his gear to them.  It's always inspiring to talk with new manufactures and get a sense of why they're into what they're doing.  Eric was one of those guys.

After Superbooth, Alex went on to Prague and BRNO CZ. as well as Glasgow, UK doing demos and playing some shows out in various venues.  He performed with the same rig that you see above, all improvised live sets.  I wish we had some video footage from the events but unfortunately, they were the type of thing where you just "had to be there". 

We will be doing more features on the story of WMD, the design philosophy, and our approach to music making in the future.  We're excited to share it with you all.


WMD at SuperBooth 2018 Posted on 26 Apr 00:00

WMD will be attending the annual synthesizer conference in Berlin, Germany, SUPERBOOTH.

We will be showing off progress on our newest and possibly most anticipated creation yet, the Advanced Trigger Sequencer Prototype.  Create long trigger sequences, save them to memory, arrange parts and songs, and save it all to memory.  Since our last showing at NAMM 2018 we've added Triplets, Mutes, Saving and loading, and a ton more.

We will be showcasing our most recent Eurorack Module release FRACTURE.

 ... and here's a little secret ...  New Digital VCA is coming at SuperBooth.  It's smaller and more powerful than the first version.  More coming on that soon ;)


New WMD Test Lab Video with live performance from Nasty Nachos Posted on 12 Jan 14:25

This jam started out with a new concept in sequencing a bass line using the WMD Arpitecht.

I was messing around with the idea of creating movement by using the Notes mask on the Arpitecht to create chord and interval shapes.  Another lane of sequencing was disabling the root note so the sequence didn't always begin on "C". Then, using lots and lots of reset gates to keep the bass line on the root of the chord progression, rather than the root of the scale.  Every once and a while i'd let up on the reset signals and let the Arpitecht roll through the chord or octaves in order to create some fun variation.

The next step was to highlight and support that bass line by adding chords and a lead with another Arpitecht and it's expander the Triad.  For this, instead of sequencing notes, I left that input empty and just used the Notes knob and Triad knob to select a standard 1-3-5 triad.  From there I sequenced both Transpose and Scale.  I would transpose the chord so it's root would be on the root note my bass line sat on.  From there I sequenced scale just a bit to switch between Major and Minor accordingly.  I personally have studied music theory quite a bit so it's second nature whether the chord needs to be major or minor.  However whenever in doubt, just use your ears.  Think to yourself, does this sound right?  If you aren't sure, just try it the other way.  It's usually pretty obvious. If it isn't, just go with what YOU like best.  It's your music :)

The text in the video outlines the voices I was using.  All but the chords, I accidently left them out (sorry). The Pads are 3 Noise Engineering Sync Iter oscillators going through the aperture filter which is having it's frequency band modulated by modbox.

A quick shout out to 4ms for making the Dual Looping Delay.  This thing is super fun and ended up being the star of the show.  I am taking the lead arpeggiation into it via a send on the WMD Performance Mixer and looping it.  It's synced to the whole song via the ping input.  Reverse, hold, and moving around the time knob helped make a super washy swell that was fun to riff on and made for a nice way to transition from one part to another.

This was a fun video to make, I hope you dig!
