Waveform Magazine The Sound of Mewsic (Project 7) – DIY Build

Waveform Magazine Mewsic Box (Project 6) - DIY Build

Sound of Mewsic - Kit

Have you ever found yourself wanting to hear a quick sample of a new module or have your speaker for your “on-the-go” case? Well, the Sound of Mewsic module from Waveform Magazine is exactly what you need. 

(You are probably asking yourself … What is it?) 

It is a small and versatile 10hp speaker module that is a quick and easy build even for the novice builders. For our latest build, we take on Waveform Magazines DIY Project 7… the Sound of Mewsic!

Consisting of a panel, speaker, a pot, a single jack, a tiny PCB and a few other components, the Sound of Mewsic took about 20-30min to complete. 

Let's get on with the build already.... the PCB

Start by placing the power header on the backside of the PCB and tacking it down, making sure you line the notch up with the silkscreen.  Next, place the potentiometer and the audio jack on the topside of the PCB and carefully flip the board over to solder everything into place. Attach the completed PCB to the panel by the jack nut.

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.
