Waveform Magazine Mewsic Box (Project 6) – DIY Build

Waveform Magazine Mewsic Box (Project 6) - DIY Build

As one dives into the modular world, you will find yourself examining or re-examining your setup almost on a daily basis. The case is one of the most important, if not THE MOST IMPORTANT piece to a modular artist. Waveform Magazine did us all a favor by putting together their new Mewsic Box. A 60HP DIY eurorack modular case that not only has style, but also functionality in more than one way. Like any project that Waveform Magazine makes, the Mewsic Box is a unique case; its functionality is more than meets the eye. 

The Waveform Magazine Mewsic Box is an all in one project and it has “optional” add-on’s that can really make this little case stand out.

For instance, how many times have you seen a case with a small plant holder built into a cable hanger? We hadn’t either and just thought this is was too badass not to check out. Another cool option is the ability to house an internal speaker so that you may use the case on the fly.

 If you purchased the Meow Mixer (see this build), you can mount it inside the case so that you don’t take up any extra precious top case space.

Every quarter we receive a new issue of our favorite magazine… Waveform. In this issue (Summer 2021 – Issue 6), a small 2HP module called the “Meow Mixer” was featured alongside a new modular case kit (aka. The Mewsic Box) as the featured project. The Meow Mixer is a 3-channel powered Eurorack module that has 3 inputs with attenuation, and 1 summed main output with an output volume control.

As with every DIY project that Waveform Magazine releases, the Meow Mixer was unique in that it could be used in conjunction with other DIY projects that Waveform released. This sounds confusing we know … but stick with us on this build and we will explain everything in detail. So, without further ado, let’s jump right into the build of the Waveform Magazine Meow Mixer!


Waveform Magazine PT2399 Delay – DIY Build

Waveform Magazine Project 1 - PT2399 Delay Module - DIY Build

When it was announced that there would be a magazine dedicated to modular synthesis, you can imagine the feedback from the modular community. Waveform Magazine was born in the summer of 2019 and upon its release it created a following.

To much of everyones surprise, not only was this a magazine that reviewed modules, manufacturers, artists, etc.. it also contained its very own DIY projects.

Project #1 was a upcycled karaoke reverb PCB that would be transformed into a eurorack delay. Otherwise known as the PT2399 Delay or Waveform Magazine Project #1, this little 5HP module inspired a whole new group of DIYers due to its new found glory of being published.

PT23.. what?

At the heart of Waveform Magazine Project #1 is the PT2399 chip. The PT2399 is a CMOS echo/delay processor developed by Princeton Technology Corp.

This digital chip includes an ADC (Analog to Digital converter), 44Kb of RAM to store the samples and a DAC (Digital to Analog converter). This chip was created as a simple solution to add delay/reverb/echo to karaokes and set-up entertainment systems. Pretty rad eh?

The PT2399 is readily available and has a minimum delay of 30ms and a maximum of 340ms (that could be extended up to 1 second at the expense of sound quality) which makes it perfect for delay, echo and reverb effects.

Waveform Magazine Switchenator – DIY Build

Waveform Magazine Project 3 - The Switchenator - DIY Build

Front Completed Switchenator

Issue 3 of Waveform Magazine (Winter 2020) is chock full of reviews, interviews, gear and even a new DIY Project. For their third DIY project, Waveform have provided us with another utility module that requires zero power and allows attenuation and signal toggling on the fly.

Waveform Magazine Project 3 is known as the one and only Switchenator!

We were thankful to take this build on and see what this module was all about!

To sum it up, the Switchenator is a dual passive attenuator and dual switch for Eurorack systems…. and it’s a little 4HP beast.

What’s this Waveform Magazine again?

As previously mentioned in our Gateway Oscilloscope write up, Waveform Magazine is the first and only publication dedicated to modular synths. With that being said, we were stoked to receive the Winter 2020 edition of Waveform earlier this month partially due to all of the new gear reviews and industry news that they provide.

One of our favorite features is interviews with the modular synth manufacturers. It’s really cool to get to read about their journeys into modular synthesis and how they started their businesses. The interviews are so well written, it almost makes it feel like you know the owner of the modular company upon completing the article.

Note: In case you missed the opportunity to get the first three issues of Waveform, you can still pick them up over at the Waveform site (which we HIGHLY recommend you do!)
