"Phaseburn One is a synthesizer built around a phase-locked loop: the main oscillator tracks a reference signal, and whatever you patch into that reference becomes part of the sound. Everything you hear is the plugin on its own, nothing else added.
In the video: the PLL lab, the morphing oscillator and its fold, four step sequencers and four LFOs, the probability sequencer, the mixer and patchbay.
VST3, CLAP, AU and standalone, macOS and Windows, instrument or effect. Free open beta until 15 October 2026.
The following is some additional info directly in via Phaseburn Music:
"I want to introduce Phaseburn One, a synthesizer we have been working on for several years, which is now in open beta and free for everyone until 15 October.
The sound is built on a phase-locked loop. One oscillator listens to another and keeps trying to match it, and the interesting part starts where it fails. When it tracks accurately the tone comes out clear and strangely alive, and when the loop is loosened you hear the chase itself: the oscillator catches up with the target, overshoots, breaks off, finds the frequency again, sometimes clinging to a harmonic instead of the note you played. PLLs are not new, they have appeared before as modules and effects, but as far as we can tell nobody has built a whole instrument around one. Four macro dials open the loop by ear, so none of the theory is needed to land somewhere usable.
Three more oscillators sit beside it: Morph, which sweeps between waveform families, a Vector shaping oscillator and a Sub. A transient module can add a click, noise or a metallic edge, or build a kick out of a sine. Around the loop there is a modular patchbay where you draw the cables yourself, a rack of seven effects and a mixer, and almost everything can be modulated from a dedicated section of LFOs and modulation sequencers.
"MemoryTone by XILS-lab unleashes a colossal three-oscillator-per-voice analog architecture—with 16-voice polyphony and up to 18 oscillators in unison—then propels it beyond its 1982 inspiration with expanded modulation, MPE, advanced arpeggiation, integrated effects, and modern sound-design capabilities."
MemoryTone is XILS-lab’s exploration of one of analogue synthesis’s most ambitious instruments — a sixteen-voice polyphonic architecture built around three oscillators per voice and a 24 dB/octave self-oscillating ladder filter.
With eighteen oscillators across sixteen voices, combinable waveforms, oscillator sync, pulse-width control and a deeply interactive signal path, its character begins long before effects enter the picture. Oscillators interact. Levels influence behaviour. Voices move. The filter responds to everything that came before it.
"Today I wanted to take a bit of time to explain my deep love for the Dirtywave M8 Tracker while going over the patch notes for the new OS that was released last week. The new OS brings a slew of upgrades to the device in both sound and presentation. Let's check it out and make some tunes."

“In the year 2000, I was in college and obsessed with modular synths, but could barely afford to eat. I knew it was possible to build your own synth, but there wasn’t anyone, or anywhere to turn to for advice. In the past decade, much more information has been published online, and in 2013 I started down my path to DIY modular. Even with all of the information online, there still lacked a single, simple, comprehensive guide for those looking to build their own synthesizer. I want AI Synthesis to be that guide. Prior to building my own synth, I was a dreamer, after building my modular, I felt I had awoken. I want to help others do the same.”

・4’, 8’ and 16’ octave ranges
・Classic Traveler filter
・Twelve factory presets
・Full MIDI CC control
・Separate modern modification section
SynBe is a monophonic bass synthesizer inspired by a 1975 Japanese Synth Bass.
I had wanted one for a long time, but finding one is difficult. Rather than wait for the right unit to appear, I started with what was still available: surviving technical documentation, published circuit information, material from related instruments, and other technical references.
Some sections are well documented. Others are incomplete. Where the original circuit cannot be fully determined, SynBe uses the available evidence, related designs, conventional modelling techniques, and listening tests.

Monophonic synthesizer architecture Triangle, Square, Saw, Pulse and Phaser modes 4’, 8’ and 16’ octave ranges Classic Traveler filter Twelve factory presets Full MIDI CC control Separate modern modification section 2x internal oversampling Versioned DSP kernel Special nice & great graphics by ME! Archaeology
Most of my previous reconstruction projects started with an instrument sitting in front of me.
SynBe did not.
The reconstruction began with surviving technical documentation and circuit information. I also studied material from contemporary and related instruments where the available information was incomplete.
The signal path was reconstructed section by section, from the oscillator and waveform circuitry through the Traveler filter and VCA.

Pittsburgh Modular Lifeforms SV-2 Lifeforms SV-2 from Pittsburgh Modular is a duophonic analog semi-modular keyboard synthesizer that honors classic East Coast subtractive architecture while packing a punch of flavorful twists afforded by modern technology. A full-blown revamp of the SV-1, it features updates to nearly every aspect of the instrument: new oscillator core, classic PGH filters updated with new character modes and overdrive stages, new spring reverb, new response curves and range modes on the ADSR envelopes, a custom 37-key keyboard with pitch-bend and mod wheels, and a redesigned interface with eighty-four patch points along the top. 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.
🎛️ 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.
👆 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.
📱 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.
💻 DESKTOP VERSION (Mac & Windows)
Available in AU, VST3 and AAX formats for all major DAWs. Presets are shared
with the iOS version.
TECH SPECS & QUALITY • Format: 24-bit / 48kHz • Headroom: Raw analog signal (-6 dB to -7 dB True Peak) • 100% RAW: Zero plugins, EQ, or compression — pure hardware voice • Signal Path: PreSonus XMAX Preamps & high-end Sommer Cable The Spirit LLX Silent II • Editing: Zero-Crossing cuts (preserved transients for one-shots; natural loop boundaries with smooth fade-outs/ins)

"@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!”.
