video upload by Robots Are Red

"Ring Mod and Wavefolding? Mobius Strip Mod?

For More info, visit: https://www.etsy.com/listing/45109599...

Modrwy is a 4hp Ring Mod and flavorful Wavefolder module guaranteed to spice up any voice.

This video explores Modrwy via some patch challenges provided by Dwyfor Tech.

Special thanks to Dwyfor Tech for providing the modules for this video."



Dwyfor Tech Modrwy - Eurorack DIY Ring Modulator, Waveshaper, Wavefolder, Analogue Multiplier

"Modrwy is DC-coupled ring modulator, based around a vintage transistor array IC, with waveshaping and wavefolding abilities based on overdriving the inputs. Despite being small and simple to use, Modrwy is full of its own flavour and can be used to modulate and morph any CV or audio source of your choosing.

Modrwy is entirely realised with through-hole components for ease of assembly. All our front panels are high-quality anodised CMYK prints on chunky, quality brushed aluminium sheet stock, made in the UK.

- 4hp wide, 3U high.
- Conforms to Eurorack (Doepfer A-100) standards.
- 33mm depth required for mounting.
- 40mA +12V, 20mA -12V

You can find the build/user manual at https://tinyurl.com/dt-modrwy - We highly recommend giving it a read before buying, to make sure it's the right kit for you.

I can assemble kits to order to provide you with a completed module, dependent on my free time. I charge £50 for my time and labour in this case. Send me a message for availability and details.

Production partners
DwyforTech makes this item with help from PCB manufacturing company, Hong Kong and Front panel printing company, Bury St, England"

Do more with your VCAs! (Eurorack Patch Tips) // Cryfder from Dwyfor Tech


video upload by DivKid

"Join us in this video for plenty of patch tips on making the most of your VCAs with things like sidechaining, driving into wave shaping, how to patch cross faders and panners and plenty more.

Here's the Cryfder dual VCA and 1950s micro tube saturating mixer from Dwyfor Tech. Like their other modules there's some fascinating inspirations and design with the module so with that in mind I have an interview with Dan from Dwyfor Tech on my website, check that out here // https://divkidvideo.com/cryfder/

A "forgettable" Buchla Filter Circuit is Reborn // 3 Patches with Pas-Isel from Dwyfor Tech


video upload by DivKid

"Pas-Isel is Welsh for Low Pass, handy that when this is a Eurorack filter module.

Dwyfor Tech are a new company who have taken inspiration from what has been said to be a "forgettable" Buchla filter circuit, smashed that into a Korg MS-50 diode ring for a resonance path and masses of lovely guitar pedal style overdrive and they've made that a Eurorack filter with bags of character, and a different tone and circuit design (it's really multiple high shelf EQs).

In the video we share some of the key points in the story of what this circuit was based on and a bit about the company. You can read more about it all on my website in this interview // https://divkidvideo.com/story-time-dw...

'3 Patches with ... ' is a video series where I pull focus on just 3 things with a piece of gear, set of functions or techniques. More of these to come alongside the larger in depth demos in the future.

You can grab a DIY kit from Pas-Isel (and request and assembled one directly) here // https://reverb.com/shop/dwyfortech

"Pas-Isel is a four-pole lowpass filter for Eurorack modular systems, with an architecture unlike any other. Combining design elements from Buchla and Korg, this diode-based VCF uses highpass filters in op-amp negative feedback loops to generate its signature 'wooly jumper' -24dB lowpass response.

Pas-Isel is entirely realised with through-hole components for ease of assembly. This listing is for the full kit version, which includes all components necessary for you to solder together straight away at home. All our front panels are high-quality anodised CMYK prints on chunky, quality brushed aluminium sheet stock, made in the UK. We also offer a panel and PCB set, if you'd rather source your own components, in a separate listing.

8hp wide, 3U high.
Conforms to Eurorack (Doepfer A-100) standards.
33mm depth required for mounting.
Idle power consumption 25mA on both rails.
25kHz self-oscillation power consumption 45mA on both rails.
