"very short video to demo the trigger input mod added to the Boss DR-110.
It enables the drum machine to be played with external gear. Any positive pulse trigger from 1v to 20v would do the trick, you can even trig the sounds manually with a AA battery if you like !"

"Portable programmable analog drum machine from the early 80s.
Unit was modded to add trigger inputs so that now you can sequence the 6 sounds and accent with external gear.
It uses optocouplers so any positive voltage pulse would trigger the sounds (v-trigger for instance). You could even trig the sound manually with a battery cell !
Unit is in fully working order. it comes with its original carrying case.
It runs on batteries or power adpater (not included). If you want to run it on power supply you'd need to get the boss PSA-120 power supply, other power adapters brings background noises.'

Introducing Fauve - VST3/AU/AAX - flawed audio reconstructor by K-Devices
video upload by kdevices
Press release follows:



Arvieux, France - April 17 2025. K-Devices, developer of creative music tools, has released Fauve, a new audio effect, as VST3, AAX and Audio Unit plugin for MacOS and Windows.
Fauve is an audio processor that collects sonic fragments and replays them — not always faithfully. It forgets, distorts, and glitches into new meanings; like the hallucination of a broken machine.
By continuously recording incoming audio, Fauve analyzes and breaks sound into small units called “collections.” When playing them back, it sometimes fails, opening space for the user to edit and shape the material according to their own sonic vision.
Fauve can be a harsh distortion, a gentle shadow, a paroxysmal dance between reality and dream, and much more. It can slightly scramble your sound, completely strip it of its original meaning, or introduce subtle, almost imperceptible variations to make it richer, yet always organic.
Fauve disrupts, but never destroys.
Fauve is a totem/series plugin, and like all totems, it follows its own logic. Timing in Fauve doesn’t rely on beats or note values — it’s driven by the material itself. Every operation is triggered by zero crossings, making the outcome deeply dependent on the source. Same settings, radically different results.
== Totem/ Series ==
Fauve is part of the totem/ series by K-Devices: unconventional audio effects coming in a compact format, easy to use, at a lower, convenient price.
== Requirements ==
Available as VST3, AAX and Audio Unit plugin
any 64bits compatible DAW
MacOS and Windows
== Availability, price, and deals ==
launch price: 24 EUR (until May 18)
regular price: 49 EUR (after May 18)

From the makers of Thing 8.
"What if your synth reshaped reality?
Alice-9 is the next-generation sample-based synthesizer forged from the chaos of the unknown and built for creators who refuse to follow.
Powered by SCO technology, and infused with analog soul, AL9 isn’t here to emulate.
It’s here to change the rules.
🎛 Real movement, deep stereo placement, aging imperfection, and punchy compression.
🎶 Every preset is a twist. Every sound a move. Every session, your next breakthrough.
This isn’t just another synth.
This is the edge of synthesis.
Choose your sound. Be the one who rewrite the rules.

Alice-9 (AL9) is a next-generation sample-based synthesizer in the digital domain, part of the Marea virtual instrument series, and powered by the innovative MUST (Modular Unified Synthesis Technology). Early testers have described it as an instrument with a deeply organic and varied sound palette — evocative of iconic synthesizers from the 1990s and early 2000s. AL9 redefines what a sample-based synth can be, merging analog realism, playable feel, and modern digital power into a single instrument. Available in VST3, AU, and AAX formats, ensuring integration with all major DAWs.

The first users compared AL9 to walking into a music store in the 1990s, hearing a synth that delivers something new and inspiring with each preset. That rare sensation of immediacy, depth, and musicality — the feeling of a “real instrument” — is the essence of AL9.
Made to Inspire
The architecture of AL9 goes far beyond sample playback or wavetable synthesis. Its sound engine is built around SCO (Sample-Controlled Oscillator), a high-resolution resampling system capable of reproducing natural analog behaviors such as frequency drift and evolving dynamics. Unlike typical static samplers or rigid waveforms, AL9’s oscillators breathe and shift like their analog ancestors.
This realism is further enhanced by the proprietary Superstereo system for natural stereo placement , the Age control that adds subtle imperfections, emulating the warmth of aged hardware and Integrated multiband dynamics processor inspired by the popular OTT compression paradigm, delivering musical glue and energetic punch.
Whether you're chasing nostalgia or forging new paths in sound design, AL9 provides an inspiring playground that rewards musicianship and creativity.
Beyond Emulation
The idea for THING originated during the development of Thing (TH8 – TH5) — an emulation of a classic 1980s DCO synth. During that process, a question arose: what if, instead of replicating digital waveforms, we could capture and reproduce the actual behavior of an analog VCO? What if we could push timbral diversity beyond the limitations of traditional synthesis methods?
