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

via Signal Sounds:

"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.

OBNE Parting // An Innovative Approach to Lo-Fi Effects

29:44 TR-1000 / drum machine demo

"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"

Tembra Modular PH LFO - Phase Shifting Wavetable LFO

video upload by Braintree56

"The Tembra Modular PH LFO is a powerful Eurorack modulation source that focuses on phase shifting and uses wavetable LFOs. I love using Phase Shift for wide stereo images and complex movement.

In this video, I demonstrate the PH LFO’s core functions and build a practical Eurorack patch that uses phase-shifted LFOs to create a wide, animated stereo field—without relying on chorus, delay, or other stereo effects.

Tembra Modular:

/ tembra.modular

https://www.tembra-modular.com/phlfo/"

LFO module provides 4 outputs, 3 with phase shift.
The PH S knob controls phase:
center = no shift,
up = maximum shift (45° / 90° / 180° depending on output),
down = the same amount but in the opposite direction.
RATE controls LFO speed.
WAVE smoothly morphs between waveforms inside the selected bank.
BANK button:
Short press: switch between waveform banks (5 banks + 1 bonus).
Hold: enter rate range selection mode.
In this mode, short press cycles rate ranges:
0.05–10 Hz, 0.05–5 Hz, 0.05–3 Hz.
Hold again to exit back to bank mode.
There are CV inputs with attenuators for WAVE, RATE, and PHASE.
Range switch selects output voltage range:
0 to +10 V or –5 to +5 V.

F*ck With Sound ships Break On Through and Bring It On Eurorack Modules

Press release follows:

F*ck With Sound ships Break On Through and Bring It On, debuting dedicated DACS Audio brand with extraordinary Eurorack modules living up to noteworthy name

GATESHEAD, TYNE AND WEAR, UK: having opened ears in October when debuting during the Bristol, UK-hosted Machina Bristronica 2025 event showcasing electronic music culture and technology, dedicated DACS Audio brand F*ck With Sound is proud to ship Break On Through and Bring It On — opening an absorbing new chapter in the award-winning high-performance, well-engineered product producer’s four-decade-spanning design and manufacturing history with a FET distortion unit (based on an extension of what was originally a microphone level limiter) and a ring modulator boasting a super-smooth sound, really low breakthrough, and switchable WEIGHT and EDGE controls (which will both be familiar to users of DACS Audio’s legacy FwS FREQue, much-lauded as a 2U rack-mount, two-channel ring modulator outboard effect), respectively, representing extraordinary Eurorack modules living up to the newly-launched brand’s noteworthy name — as of December 15…

As a FET distortion unit based on an extension of what was originally a microphone limiter, the basic circuit behind F*ck With Sound’s Break On Through module has been used — and abused! — by producers for years, more recently emulated as a plug-in, before being effectively adapted to join the ranks of the ever-expanding Eurorack marketplace. Maintains DACS Audio Managing Director Dr Douglas Doherty: “After reading about Soundtoys’ Devil-Loc plug-in, I was intrigued. We were looking for a distortion unit to go in a mic pre under development. I had heard about Tchad Blake’s work with the original Shure Level-Loc — particularly on drums, and this seemed like a bit of serendipity that had to be acted upon! The perfect fit. In the end, we didn’t proceed with the mic pre, but it was clear that this would be ideal for modular system users.”

Bringing Break On Through to market as a 14HP-sized Eurorack module — based on a classic analogue microphone limiter design that was, according to legend, hijacked by an electronics-savvy record producer, and used on numerous records for ‘breaking through’ with drums and percussion, particularly — was easier said than done, however. “As always, there were many hurdles,” admits Dr Douglas Doherty, before continuing: “The original circuit was for microphones, so it had to be upped for line level; it was single voltage rail, so had to be adapted for dual voltage rail; the interaction of the threshold and input gain needed some tweaking; and we wanted to adjust the release. After a few prototypes, we arrived at the current unit, which is very responsive and versatile. Control-wise, it has an input gain [IN GAIN] and a threshold setting, which we call BREAK; as well as the manual BREAK control, there is also a CV input [IN] to modulate the threshold. There is a variable RELEASE control that can produce some very interesting results, depending on the nature of the input. On the output, we also have gain [OUT GAIN], and a CV input [IN] to modulate the output level [GAIN MOD].”

Musically speaking, the end result “…is a brick wall limiter that can — by upping the input level — be pushed into distortion,” describes Dr Douglas Doherty, justifiably proud of the fact that F*ck With Sound successfully upgraded and updated the circuit concerned to produce a colouring block with a vast pallet. “With dynamic material such as drums, it can be set for only peaks to distort — the rest remaining clean. That quality was commented upon by a couple of distortion aficionados atMachina Bristronica.” Break On Through features — hitherto unmentioned — worth highlighting here include: LED indication for distortion; solid metal sleeve jacks for longevity and stability; and custom DACS Audio aluminium knobs.
