A New Favorite Reverb and Delay Eurorack Module: Cosmic Debris

video upload by EZBOT

"The Cosmic Debris is a playable Delay and Reverb module by WMD. Today we check test it on chords and ARP's to see how it performs with melodies. Delay is what reverb is before it becomes reverb. One of the great things about Cosmic Debris is that it can be either and you can fade between the two ideas in real-time."

"This monstrous synth is in great shape and sounds fantastic. There are eight analog voices which can be panned individually for some really interesting stereo sounds. The keyboard can be split or doubled and there are two oscillators per voice. It is a very warm sounding synth great for massive chords, basses and leads. This model has MIDI in out and thru.

It is quite a beast, with all the great 80s vibe and that classic Oberheim sound. In fantastic working and cometic condition overall. Fully serviced along with new wood sides. Serial No. C30418"

Sequential Multi-Trak 61-Key 6-Voice Polyphonic Synthesizer

Additional SYNTH CITY Listings

"The Sequential Multitrak (released in 1985) is a six-voice analog synthesizer notable for combining true analog sound with early digital control.

Each voice has a CEM3394 synth-on-a-chip, offering a single oscillator, sub-oscillator, noise source, and resonant low-pass filter. It was one of the first affordable synths to feature a built-in sequencer and MIDI implementation, making it popular for both studio and live use.

The Multitrak’s panel and parameter editing system allowed deep sound design, though programming could be a bit tedious. Its warm, punchy tone and distinctive Sequential character make it a cult favorite among vintage synth enthusiasts today.

This one works like a charm and has that analog warmth you've been looking for in a polysynth."

Introducing Cosmic Debris from WMD and Infrasonic Audio

video uploads by WMDevices

"Cosmic Debris is a powerful delay and reverb engine built for modular explorers who want more than just echoes. With 16 interactive delay lines, multiple performance modes, and a design tuned for live use, Cosmic Debris can move from precise rhythmic repeats to infinite atmospheric washes in an instant."

2. 3 patches with WMD Cosmic Debris
3. WMD Cosmic Debris - In-depth overview and tutorial

See additional posts featuring Cosmic Debris here.


"A collaboration born in the Denver modular community

Cosmic Debris began as a design by Nick Donaldson of Infrasonic Audio, a fellow Denver modular enthusiast we met through our monthly Freq Boutique gatherings. Nick approached WMD for advice on manufacturing, and as soon as we heard the sounds he was creating, we knew there was something special.

From there, the collaboration took off. We worked closely with Nick to refine the design, bringing in ideas to expand the feature set, streamline performance controls, and ensure the module would be rock-solid for production. The process has been as rewarding as the results: not only has Cosmic Debris grown into a truly versatile delay and reverb processor, but we’ve had the joy of building a deeper friendship through the design journey.

Cosmic Debris is a powerful delay and reverb engine built for modular explorers who want more than just echoes. With 16 interactive delay lines, multiple performance modes, and a design tuned for live use, Cosmic Debris can move from precise rhythmic repeats to infinite atmospheric washes in an instant.

At the core, Spray transforms traditional delay taps into massive ambient reverbs, while Scatter reshapes the feedback paths and interactions between lines to create ever-changing textures. Time and it's shift function SLEW take traditional modulation and flip it on its head with huge risers, crossfading delay time changes, and hands on control over the energy of the sound caught in the buffers.

A built-in band-pass filter lets you carve space in the mix or push the signal into motion with CV modulation.

Cosmic Debris is designed with performance at its heart. Blast delivers a momentary boost into the delay input as well as 100% send level (in send mode) for explosive bursts of sound with natural tails, while Send Mode turns the Mix control into a CV-controllable send/return level, perfect for insert-style processing.

Flexible sync options include clock input, tap tempo, or free-running mode, keeping you locked in rhythm or drifting into uncharted time. A dedicated Freeze function captures audio into a timeless loop, letting you hold textures indefinitely.

Three unique processing modes, Blur, Ratio, and Warp, expand the palette even further, from smearing reverbs to pitch-shifted delays. Combined with its intuitive interface and deep modulation capabilities, Cosmic Debris is equally at home in a live performance rack or a studio sound-design system."

New DX7 Patch Bank with 80s Magic | Download now!

02:30 Demo of patches in more detail

"Get my new DX7 Patch Bank now — a premium collection of 32 of my best Electric Piano voices for the Yamaha DX7, DX7II and TX802, and for software or hardware that can import or load original Yamaha DX7 / DX7II voice data.

Price is only $12USD for the bank. You can get the bank from me directly through email here: espenkraft69@gmail.com You can also get the bank here:

https://thepatchbay.io/product/yamaha...

This is not a random bank put together overnight. These sounds have been with me for decades — some of them all the way back to the 1980s. They have been carefully selected, edited and refined over many years, and used by me on my own albums as well as in commercial music productions. Every sound in this collection earned its place. There is not a single filler patch here.

All 32 voices are Electric Piano based, but they sound much more varied than that. The have a wide musical range inside their category: some are glassy, some bell-like, some harder and more cutting, some soft and smooth, and some have that extra glossy, polished sheen that makes a part instantly sit right in a track. Some are more like pads, while others can be used as leads or bass depending on where you play it on the keys.
They are polished for maximum musicality and usability, and they work especially well either on their own, layered with other voices from this bank, or combined with other sounds in a full arrangement.

Playing with Parting - Old Blood Noise Endeavors & Emily Hopkins

video upload by Molten Music Technology

"Running a simple bass line through the stunning Parting glitch/ambient machine and exploring the sounds. It's a very touchy feely pedal that's wasted on guitarists and really should be a Eurorack module. Full review coming soon from a synth perspective.
I bought this pedal myself."



"Parting is a box of pleasant surprises. Moments of chance will give bursts of a glitch delay that can smear into a reverb, modulated by tremolo or vibrato, filtered, and, most importantly, dissolved into lofi aliasing or stretched out reverse. All of this may jump around in halves and octaves of itself - it’s up to you and Parting, together.
Controls

Dissolve has two functions. Below noon, it reduces sample rate, creating an increasingly degraded version of the signal. Above noon, it reverses the signal, and repeatedly cuts the reverse clock in half as the knob is turned, creating an increasingly long and degraded reverse.

Rate sets the rate of the modulation LFO, which is also the frequency of triggers for moments of chance.

Depth sets the depth of the LFO.

Shape sets the LFO shape: Sine, Square, Reverse Saw, Saw, Random Sine, Random Square, Envelope

Chance allows random bits of signal to enter the delay/reverb buffer during an LFO cycle.

Smear adds diffusion and feedback to the delay lines, turning them into a lush reverb as the knob is turned up.

Glitch creates various clock subdivisions.

Time sets the timing of the delay/reverb, as well as the reverse.

Filter sets the cutoff point of the post-dissolve filter.

Mix sets the blend of dry and wet signal.

Aux switch for tap tempo, half speed, or preset switching.

Soft-touch On/Off footswitch with relay switching for minimal switch noise"
