15 minutes with Smoothie Audio Smear, a 98-pole allpass filter

video upload by Signal Sounds and Tom Churchill

"Tom takes a look at Smear, the debut module from Smoothie Audio. It’s a dual stereo 98-pole allpass filter, and it’s capable of some pretty mind-bending spectral effects.

"We say...
It's not often that we come across something genuinely new and innovative in Eurorack these days, but Smear is just that - a pair of stereo 98-pole all-pass filters that open up all sorts of strange sonic territory. Brilliant!

Manufacturer's description
Smear is Smoothie Audio’s first Eurorack module - a dual stereo 98-pole allpass filter unlike anything else in your rack.

At its core, Smear takes a deceptively simple concept - the allpass filter, usually buried deep inside reverb algorithms — and refines it into a playable, sculptural processor. A single allpass subtly shifts the phase of incoming audio while passing the entire signal unfiltered. Stack 98 poles in series, and the effect becomes striking: frequencies across the spectrum are delayed by different amounts, creating a rich spectral delay that can smear, morph, and transform sound.

Smear can be become different effects, according to how you set the parameters:

Transient Smearing & Spectral Delay that reshapes transients, can add punch
Resonator & Percussion Voice for metallic, physical-modeling tones when pushed into feedback territory
Morphing filter & Phasor for animated timbral movement
Interface & Controls

The panel is laid out symmetrically, with two identical sections (Left and Right). By default, stereo audio flows left → right → out, but a dedicated Split Mode allows each side to process audio independently.

Each section offers three core parameters — Frequency, Resonance, and Stages — each with dedicated CV inputs. Frequency and Resonance have attenuverters for precise modulation. A global Feedback control (with CV) unlocks resonant, flanger-like, and physical-modeling behaviors.

The Stage sliders reveal Smear’s hidden depth: with LEDs indicating crossfade modes between filter poles, you can dive into complex notch filtering, animated flams, and evolving timbral movement. Modulate them, and the module comes alive with unpredictable, dynamic filtering effects.

Stereo Triple Filter Network & Resonator // 3 Patches with OPALINA from Hieroglyphic

video upload by DivKid

"Coming in hot after Hieroglyphic's first release 'Plume' here we have OPALINA which is a stereo spectral playground. It's billed as a filter network, with triple band pass resonator modes and an isolator multi mode network. It has multi band outputs for creative modular processing, with the including expander it also has specific (and stereo) low mid and high band inputs. Loads to go at, but distilled down into exploring 3 patches here for our 3 PATCHES series of videos."

Make Noise Trio: 50 Combo Patches for Strega+0coast+0ctrl. No Talk Sound Demo. Live Jam/Performance

video upload by Anton Anru

"VOLTAGE IN SHADOW is a collection of 50 combo patches and patterns for a semi-modular system by Make Noise: 0-COAST + 0-CTRL + STREGA. It includes textures, basses, leads, drones, chords, percussion, and FXs.
💎 There is a wide range of timbres inside the pack: soft and bright, musical and experimental, harmonic and FX-like, cyclic and generative, slow and fast, analog- and digital-style, dry and atmospheric, clean and distorted.

📦 Get these patches: https://antonanru.sellfy.store/p/make...

🦠 This is one of the most complex works I’ve done. It required a lot of time and effort, but I also received huge pleasure and inspiration while working with such interesting and unique devices.
The patches turned out to be very fluid, dynamic, and non-static — largely due to the “alive” and sensitive nature of the synths. However, this also creates some difficulty when recreating the patches from images: even small changes in knob positions can affect the final result.

Jamuary 29 2026 - Folding Entertainment System

"What have you done! Wavefolding the dulcet tones of the Nintendo Entertainment system is blasphemy! But it does sound pretty sick, right. Shredded nostalgia injected srtaight into my earholes. As a side note, can somebody explain to me why the NES pulse wave is so recognonizable? it just sounds grittier and angrier than other pulse waves. Am I right? or have i lost it? #NES #midines #rolandP6 #polyendtracker #nts1mk2"

2 patches with the Voltage Multistage 16

video upload by Stazma

"As i'm still working on a big demo for this beast but will still take some time I thought I would share two unusual sequencer patches with the Verbos Multistage 16.

It will also be a good opportunity to talk about the other modules, how I like to patch them, show of a few patches to demonstrate how all this can sound.

Have fun!!!"

Torso Live Session #3: Lorenzo Colombo

video upload by torso electronics

"Torso Electronics presents the third live session recorded at our office space in Copenhagen.

In this episode, percussionist and sound artist Lorenzo Colombo presents an electroacoustic concert featuring the T1 and S4 in a hybrid setup combining metal percussion instruments and solenoids.

The performance is driven by the T1, used as both sequencer and live MIDI keyboard. It controls the SOMA Pulsar-23 and a set of dadamachines solenoids. The solenoids hit a set of Kolberg percussion bell plates, which function simultaneously as acoustic instruments and conductive metallic surfaces. Through body-resistance and circuit-bending interactions, these plates influence electrical signals and directly modulate the Pulsar-23 as well as generates MIDI that control the same instrument . All audio is routed into the S4, used as the sole sound-shaping and modulation unit.

About Lorenzo Colombo
Lorenzo Colombo is a Copenhagen-based percussionist, performer, and sound artist dedicated to contemporary and experimental music. He teaches percussion and post-instrumental performance at the Royal Danish Academy of Music, where he earned his Soloist Diploma in 2023. A recipient of the Léonie Sonning Talent Prize and Musikanmelderringens Kunstnerpriser, Lorenzo was also part of Statens Kunstfond’s Den Unge Kunstneriske Elite program (2023–24)."

Abstract Loops and Shifting Rhythms | Which time is this 2026-01-29 by atnr

video upload by atnr

"This piece was created using the ‪@teenageengineering‬ EP-133 K.O.II, OP-1 field, and tape loops. Within repeating harmonies, abstract textures emerge as drums and tape loops continuously change through effects.

The EP-133 K.O.II and OP-1 field are synchronized via USB. On the EP-133, a simple drum pattern is played and shaped using Punch-in FX.

The OP-1 field plays the bassline and harmonies, with the sound processed through ‪@ChaseBlissAudio‬ MOOD MKII using delay and reverb.

A piano performance is recorded onto a tape loop and played back. The sound is heavily processed through LOST+FOUND, transforming it into an unrecognizable texture rather than a conventional piano tone.

Additional layers are created using VST instruments within a DAW."
