Moreover, a 24hp Eurorack expansion bay with three power headers sits alongside them, so external modules of your choosing can be dropped into the signal path at any point.
"OktaDie is an 'organismic' synthesizer for iPad: eight touch-sensitive voices,
a cross-modulation matrix, a dual modulated delay and an overdrive — with no
keyboard, no scale and no quantisation anywhere in the signal path.
No talking in this video: just hands on the glass. Everything you hear is
OktaDie running standalone on iPad (AUv3 plugin versions included), played
entirely on the eight pads — no MIDI keyboard, no sequencer, no external
processing.
π️ ABOUT THE INSTRUMENT
The eight generators are closer to a vintage electric organ than to a VCO.
TUNE moves each voice continuously across a huge untempered range, SHARP
morphs the waveform from triangle to square, and the envelope shapes pitch
and waveform as it moves instead of just opening a VCA after it. Voices work
in four pairs and two groups, each pair picking its own modulation source —
another pair, the Hyper LFO, or the instrument's own output. TOTAL FB feeds
the post-distortion signal back in and turns the whole machine, delay and
drive included, into one giant FM structure. Noise, bleed and drift are
features here, not defects: it never produces exactly the same sound twice.
π PLAYED BY TOUCH
Eight multitouch pads replace the keyboard. Play with several fingers at
once, slide sideways to glide from one pad to the next, press harder to open
the envelope further — OktaDie reads the contact area of your fingertip, and
Apple Pencil pressure where available.
π± iOS VERSION (iPhone & iPad)
Standalone app + two AUv3 extensions: OktaDie as an instrument and OktaDie FX
to run your own audio through the delay, drive and feedback loop. Works in
AUM, GarageBand, Cubasis, Drambo and Logic for iPad.
π» DESKTOP VERSION (Mac & Windows)
Available in AU, VST3 and AAX formats for all major DAWs. Presets are shared
with the iOS version.

"@matthsmatthsmatths takes a look the @EricaSynths. Erica Synths Razornator, developed with 112dB, its an effects unit built around five stereo, chromatically tuned resonating delay lines.
We look at how the Razornator turns rhythmic, unpitched drums into pitched, harmonic textures.
A resonant filter shapes the input, while decay, damping and an envelope follower control the length and tone of the resonance.
A shift control can move the pitch by up to two octaves, a central dial sets the root note, with four further pitches set by hand or via MIDI for chords and sequencing.
Razornator shares its form factor with the Echo Locator and Nightverb, offering stereo I/O, MIDI, USB, up to 25dB gain and extensive MIDI CC control.
Matt runs presets on drums, synths, arpeggios and vocals.
Priced at around 490 euros, expect firmware updates to follow."

"A dub techno piece created with the Roland TR-606, OP-1 field, and volca fm2.
The TR-606 is recorded through two separate signal paths. One path is processed with reverb through the blueSky. The other is filtered with the GE-7 to retain only the high frequencies, then processed with delay through the DD-6.
On the OP-1 field, an electric piano sound processed with the CWO effect is sent through the MICROCOSM. The MICRO LOOP effect is used to extend and layer the reverberant textures.
The volca fm2 receives the signal from the TR-606 TRIGGER OUT through its SYNC IN and is synchronized with the drum machine. The volca fm2 plays the bassline.
In the DAW, the low frequencies of the TR-606 are reinforced, and vocal samples processed with echo are added to the arrangement."
"The Relic by Shear Electronics is an ambitious, discrete analog polyphonic synthesizer that serves as a highly authentic tribute to the classic 1970s Oberheim OB-X.

"Erica Synths Razornator is the 4th 112dB collaboration FX unit and it's a resonator like no other. In this hands-on walkthrough I build an entire track (strings, dubby stabs and thunderous bass) from nothing but short pulses of noise fed into its Karplus-Strong like resonators. If you want to know what the Razornator actually sounds like before you buy, this deep-dive demo is for you.
The Razornator packs 10 resonators (five stereo pairs), a resonant low-pass filter, +24dB of input gain, a built-in compressor and an envelope follower — all fully MIDI controllable. Originally a 1983 Karplus & Strong algorithm for plucked-string and percussive tones, Erica Synths and 112dB have turned it into a wildly flexible tone-generation and sound-mangling machine. I run through the signal path, the root/offset tuning, the gorgeous presets by Eraldo Bernocchi, and push it hard with synths, hi-hats and kicks. Resonator, but not as we know it."

"A unique stereo FX unit with an algorithm developed by Dutch company 112dB, the Razornator features 5 chromatically tuned resonating delay lines that can emulate the resonance of physical objects - bodies of instruments, rooms, structures. Chromatic tuning of the resonating delay lines makes the effect particularly musical, because it allows for aligning them in chord-like intervals, while the built-in envelope follower adds dynamics to the processed signal. Featuring 12 parameters for detailed sound design, save/recall functions for all parameters, MIDI control over all parameters and a sleek aluminium case to match our lineup of compact desktop units, the Razornator will let your setup take flight in any live show, studio or sonic experiment.
The Razornator combines several well considered and tuned “modules” for stereo audio processing with the aim of altering the harmonic content of the incoming signal. The signal path starts with an audio GAIN STAGE that boosts signals up to +24dB (it can effectively act as an analogue overdrive), then the signal is fed through the lowpass FILTER with a RESONANCE control and after filter treatment it passes through five chromatically tuned DELAY-BASED RESONATORS that can be manually tuned or controlled by the ENVELOPE FOLLOWER. After the resonators, the signal is summed and limited by the COMPRESSOR, then mixed with the dry signal and passed through the EQUALIZER and finally is sent to BALANCED OUTPUT stage.

"Up for sale is a super rare Macbeth Elements EL2 analog synth, hand-built by Ken MacBeth back in 2019 in extremely limited run of only 30 units, as said by himself - the best ever analog synth he ever built in his life… Described by him as “Elements on steroids, circuit wise”. Please do not mislead this with a regular silvers Elements - EL2 is one of a kind the way different unit. It features a striking black aluminium chassis, gold plated touch up keyboard and a very deep vintage style circuitry using through-hole components and 70’s vintage new old stock semiconductors and metal ICs. Three highly versatile discrete voltage controlled oscillators with individual audio outputs and advanced sync capabilities, classic architecture with subtractive signal path featuring unconventional filter slopes, a built-in spring reverb and a tape echo simulator. All this mixed up with a wide-ranging modulators and large tactile potentiometers for deep sound sculpting. Also, Ken decided to completely remove MIDI support making the priority to CV: he noted that most musicians use the instrument with Control Voltage and modular setups anyway. Removing MIDI parts freed up physical space and optimised the pure analog circuitry. VCO1 and VCO2 now get their own knobs instead of sharing just one. New spring reverberation circuit in EL2 provides a much deeper, different sound than the first model. Cross-modulation expanded as well: VCO3 syncs to VCO2 and VCO2 can now syncs to VCO1 directly. Of course, inspired of the legendary EMS Synthi, but ones you came across both in one room - you will definitely can’t choose which one is better here. EL2 will be never produced again and it’s already a holy grail in the world of analog synths. This exact one is number 15 of 30. Comes with the original power supply. Everything you can see in the pics is included in that sale. Was a beloved studio toy, but now it’s time to go! In excellent overall and technical condition.

The ellitone groov~e console is a new variant of the original groov~e device. The console version includes the same sounds as the original, but features several new additions including built-in stereo speaker system, battery-power, hardwood body/knobs, and individual volume control over each sound layer
The groov~e console is a fun and mysterious interactive drum-machine and polyphonic-synthesizer that automatically generates musical “grooves”. A “groove” consists of 3 individual sound layers: a drum-machine layer, an ambience-sample layer, and a polyphonic-synthesizer sequence layer. Each of these 3 sound layers can be individually tweaked or swapped out to find the right mixture of sounds to make you say “WHOAH, that’s funky!”.

"At Superbooth 2026, I spoke with Timo from Supercritical Synthesizers about one of the most ambitious analog polysynths on the market today - a unique 6-voice analog polysynth from Finland that takes a very different approach to synthesis.
With 96 analog oscillators, multi-timbral architecture, MPE support, evolving firmware updates and a variable character engine that can shift between different vintage-inspired flavors, Redshift 6 blurs the line between traditional analog hardware and modern software flexibility.
In this interview and sound demo we talk about who Redshift 6 is for, how its unusual interface works, the latest firmware innovations, and why some of its sounds might make you think you’re listening to a DX-style digital synth - even though the signal path remains analog.

"Splines is a visual vector curve generator in Eurorack format, with a wide frequency range and a built in quantizer, cv scope and cv processing capability.
It can be used in ways similar to a wavetable VCO, LFO, step sequencer or envelope generator.
Onboard quantizer scales, backups and firmware updates are managed as you would use an external USB drive.
It’s a small, shallow, multifaceted addition to any setup, and for touring rigs it can fill many roles in exchange for little space and weight.
in depth. In the technical sense "splines" are most commonly used in 3d modelling, animation and vector graphics. It's essentially just a way of creating a curved path from one point to another.
In this module, you have up to sixteen user configurable points or nodes which function much like a step sequencer, where the X axis represents time and the Y axis represents voltage.
When the phase(time) reaches the X position of a node, the 1v/oct output changes to the Y position value of that node.
Each of the sixteen nodes also has a configurable trigger setting, determining if the gate output goes high when the phase crosses the X position of the node.
The nodes are connected by a spline and the shape of this spline is determined by three parameters; Tension, Continuity and Bias. The spline output gives you a voltage following this curve.
Tension changes how extreme the curve between the nodes is.
Continuity sets the angle of the spline at the node.
"MORPHOR presents at the Superbooth 2026 the new ECHON 6, the world’s first polyphonic synthesizer based around analogue BBD resonators
Each of its six voices features a discrete BBD delay-line resonator that tracks the keyboard producing organic overtones and complex harmonic depth. Allowing you to excite these resonators in creative ways, Morphor ECHON 6 will generate anything from plucked and bowed strings over leads and basses to big pads and evolving soundscapes. With comprehensive multi-timbral capabilities, a 9×32 modulation matrix and a full analogue signal path, ECHON 6 unites experimental sound design with classic polyphony."
"The Erica Synths Syntrx II is one of the most talked-about synthesizers of recent years — but three years on from its release, is it still worth your money? In this in-depth review and demo, I finally get hands-on with this modern spiritual successor to the legendary EMS VCS3 and EMS Synthi, and I want to bust two big myths: it's NOT as complicated as it looks, and it's NOT just a crazy sci-fi sound effects machine. πΉ What's covered in this video:
-Syntrx II vs the original EMS VCS3 / EMS Synthi — key similarities and differences -Syntrx II vs Syntrx I — what changed and why -The 16x16 digital pin matrix explained simply -Using the Syntrx II as a standard 3-oscillator monosynth -The trapezoid (looping) envelope in practice -All-analog signal path walkthrough -Onboard 3-channel sequencer, DSP reverb and delay, envelope follower FM, self-oscillation, noise modulation, and filter techniques -Sample & hold circuit — how to set it up -The joystick as an LFO / recording modulation source -MIDI setup tips (offset fix, CC assignments for X and Y axes) -Patch saving — what it DOES and DOESN'T save, and why it matters -Honest pros and cons
π΅ Extended drone demo — 5 minutes of the Syntrx II running a single live patch with the trapezoid looping envelope, FM, noise, filter modulation via joystick, and DSP effects. The full version was over 10 minutes — it really is that good.
π· Price context: Original EMS Synthis now sell for £24,000+. The Syntrx II comes in under £2,000. If you've ever wanted that Synthi sound without selling a kidney, this might be your answer."
