X1L3 - ALLEYKAT - LAST NINJA 2 - 8580 SID - EURORACK MODULE

video upload by X1L3

"By ear cover of the central park loader and in game music from The Last Ninja 2. Originally written by Matt Gray for the C64 in 1988 📺🕹️🔥

Performed on the Alleykat module loaded with an 8580 SID 🐈🐾🎵

Three yarns modules and a midi to gat module are used for the nine control voltage and thirteen gate signals required to do this in this midi to cv/gate eurorack kind of way. I probably need to make myself a 4x yarns build and a mega midi to gate module one day ⚙️🔧🪛

The real thing doing the real thing. No lazy 'file player' action, and absolutely no "passionate about retro " 'technician ted / just jamie' flavoured AI generated twenty vids a week edge lord fish for clicks shovelware crud that i find myself having to trawl through and ignore on here these days 💀🙈❌

The module has been tested with the 6581, 8580, SwinSID and public domain SID and SIDkick pico to date. The SIDkick pico doesn't seem to want to play nice with it. I've yet to figure out the reason why. But the real SIDs and the PDSID and SwinSID have worked flawlessly 👌👌💯"

New Kawai K3 editor and librarian | And it's FREE to Download

"My sound patches: https://espenkraft.com
Kawai K3 & K3m patch editor and librarian — it runs in your web browser.
A tool I built to edit and organise sounds on the Kawai K3 and K3m hybrid synthesizer.

Tweak every parameter on screen, pull single patches or whole banks off the synth, back them up as sysex files, or load sysex files from your computer and into the hardware.
I added a little on-screen keyboard too, handy if you're using the K3m.

It runs in a web browser (Chrome or Edge — not Firefox or Safari) with a MIDI interface connected to the synth. It works on PC and Mac, and under Linux.

It's my personal tool shared for anyone who wants it. Setup instructions come in a short readme with the file, but I offer no support on this. It's shared 'as is'.

You can find it in my web shop here (it doesn't cost anything): https://espenkraft.com/b/6r5k7

"👉 🔥 PLAY MY C64 SYNTHESIZER — FREE, IN YOUR BROWSER: https://doctormix.com/doctormix64 🔥 👈 This is the one. My Commodore 64 synthesizer is FINALLY finished — and it came out better than I imagined. 🎹"

"Sam from Look Mum No Computer built me the control panel, but I'd been keeping it in an ugly functional box that was destroying the look of the C64. So in this episode I build it a proper detachable enclosure from scratch — measuring, cutting, gluing, a LOT of sparks, and one or two moments where I call myself an idiot on camera. 🔥

Then the good part. SID chip number one was completely dead — so I repaired it. Which means there are now TWO vintage SID chips running at the same time, one hard left, one hard right. That's not a stereo effect. That's two synthesizers playing together. 🎚️

And somewhere along the way I fell down the electronics rabbit hole — learning the oscilloscope, building my own MIDI tester out of a £12 screen and a microcontroller, and using AI to modify the firmware so the C64 screen now says DOCTOR MIX instead of Cynthcart. Being able to dominate your own electronics is MASSIVE.

Oh — and I built a virtual version of the whole thing that you can play in your browser for free. It's very beta, almost alpha, but it's real and it's yours. Link at the top ⬆️"

Kepra - Circuit-Modeled Rhythm (demo)

video upload by Hügelton Instruments

"Kepra is a rhythm instrument developed through detailed analysis of an original Japanese vintage programmable rhythm machine.

Rather than relying on sampled sounds, Kepra recreates each instrument by studying the original analog circuits, measuring waveforms, analyzing spectral content, and reproducing their behavior in software.

Features

• Circuit-inspired drum synthesis
• 12 drum voices
• 16-step sequencer
• NOTE / FLAM / ACC layers
• 8 pattern banks
• Stereo mixer
• Drive and character section
• Internal, host, and external MIDI clock

Available for macOS (AUv2 / VST3) and Windows (VST3).

https://hugelton.itch.io/kepra"


"Hardware Archaeology

Developing Kepra felt less like sampling a drum machine and more like studying an archaeological artifact.

Every instrument was investigated through circuit analysis, waveform measurements, timing analysis, and spectral comparison to better understand how the original hardware produced its sound.

Rather than reproducing recordings, Kepra attempts to reconstruct the behavior behind them.

The Missing Instrument

One voice in Kepra did not exist on the original hardware.

The Shaker was designed as an 'imaginary expansion'—a voice inspired by the architecture and character of the original instrument.

Instead of adding a modern sample-based shaker, it was developed by asking a simple question:

'If the original designers had decided to include a shaker, how might they have built it using the same technology?'

The result is not a historical reproduction, but a speculative reconstruction that aims to remain faithful to the design philosophy of the original machine.

Not an Emulator

Kepra is not intended to be a museum piece.

It is a modern rhythm instrument built from careful hardware analysis, extending the ideas of a classic Japanese drum machine into new creative territory."

WITH ORIGINAL DOCS- YOU'RE GONNA NEED THOSE

iNSTALLED IN CUSTOM DIY CASE , midi IN, OUT AND THRU

A genuine piece of underground electronic music history: the DJMC by Analogue Solutions, one of the UK's most respected true-analog synth builders. Long before "expressive control" was a marketing buzzword, Analogue Solutions built this twin-joystick MIDI controller with crossfader for performers who wanted real, tactile, two-axis-at-once control over their sound — no touchpads, no menus, just raw hands-on movement.

This thing was never mass produced. Analogue Solutions has since shifted entirely toward their acclaimed eurorack and analog synth lineup (Colossus, Leipzig, Telemark, Nyborg, and more), and the DJMC has completely vanished from their current catalog — it doesn't show up anywhere on their site today. they almost never surface secondhand. If you've been hunting for one of these, you already know how rare a find this is.

Perfect for:

Collectors of obscure UK analog gear
Live performers wanting expressive dual-axis control (filter/resonance, X/Y FX, pitch/mod)
Modular heads running MIDI-to-CV for joystick-driven patching
VJs/lighting rigs that read standard MIDI CC
A genuine, hard-to-find piece from a small builder with a serious cult following in the analog synth world — grab it while it's here, because another one might not turn up for a long time

PlantsSystem-KOSMOS3 InteractiveReverb

video upload by plantssystem

"KOSMOS3 is an interactive reverb instrument that transforms reverberation from a static audio effect into a playable, responsive acoustic space. Instead of applying a fixed ambience, KOSMOS3 continuously reshapes its internal reverb field based on incoming audio, gestural control, and real‑time modulation signals.

At its core is a multi‑parameter reverb engine capable of smooth, expressive morphing across decay, diffusion, pre‑delay, and spectral balance. These parameters respond immediately to performance input, allowing the reverb to behave like a dynamic environment rather than a background effect.

Key features include:

Interactive control via MIDI, OSC, TouchOSC, and HID
Real‑time modulation for shaping spatial texture during performance
Headless operation suitable for installations and long‑running setups
Instrument‑like behavior where the reverb becomes an active part of the performance

KOSMOS3 functions not merely as an effect processor but as a playable acoustic space—a reverb you can push, bend, and sculpt in real time."

Tempera Quirks and Foibles by Benge

video upload by Memetune Studio

"I’ve been exploring granular synthesis since around 1997, when Native Instruments brought out Reaktor, because it was the first system I knew of that had a granular synthesis engine built into it

But even before that I was experimenting with certain samplers that could do a sort of proto-granular thing where you could control the loop start and end end points of a sample independently, and use sliders to scroll through the sample by hand (for example on the Fairlight CMI 2X and also the Akai S612)

But nowadays we have it so easy, as there are a whole slew of desktop granular devices coming out, often based on ARM chips, such as the Tasty Chips GR units, the recent Waldorf synths, the Torso S4, Endorphines Evil Pet, not to mention the Mutable Instruments Clouds and its many derivatives

And then there's this little monster, The Beetlecrab Tempera - a strange and tiny box which takes granular synthesis and does something completely unique with it

It’s got 8 stereo granular samplers at its heart, but the way you interact with them is using the 8x8 touch-points. They are called emitters, and you play them either over midi or using some of the touch-points. You can change and trigger emitters in x - y directions, and it's all extremely complex, and things can get really wild very quickly, so as this is my first patch on it, I decided to keep it simple by using just 2 of the 8 grain samplers

I captured the samples myself using the built in mic (sample 1 is just tapping the box with my fingers, and sample 2 is me humming

It also has comprehensive mixing and FX processors, so here is a little ambient sketch done in real time, using just the Tempera

I’m going to have fun exploring this thing - especially when I integrate it into some of my modular systems, once I have got my head round its many quirks and foibles"

ako - Basic Microwaving (4 track tape version) - recording w MT-50, MMT-8, CZ-1000, PSS-480, TR505

video upload by ako

"Here's a video of the recording of the B-side for my new single (links to all formats below). It was recorded on a Yamaha MT-50 four track tape recorder with a Casio CZ-1000 (bass, this is honestly the weirdest synth I own and I think this the only track I’ve released with it on bc it’s just so weird), Yamaha PSS-480 (lead, despite masquerading as toy this thing packs some serious heat) Yamaha DX21 (chord layer) and Roland TR505 (drums – this gets some stick from TR purists, but it has some really usable sounds and the sequencer is super nice). The track was sequenced with the frankly legendary Alesis MMT-8 (the only hardware MIDI sequencer I’ve ever enjoyed using). Synchronisation between tape and MIDI was achieved using a Yamaha YMC10 MIDI clock to tape-synch converter. Dub style delays used on the lead came from a RocLab DD3000 (pretty obscure unit, sounds nice if you tweak it just right); Reverb came from a Behringer DR600 (solid reverb pedal, even more solid price at ~£25) and chorus for the bass via a Boss CH-1 Super Chorus - my favourite chorus, to me it just sounds how chorus should sound (this one is a vintage ‘made in Japan’ model, so fully analogue compared to later digital CH-1 models, and just sounds super warm). It was mixed on MT-50 but also with a Peavey Unity Series 2000-16 (for submixes and sends etc.), this mixer has a flavour all of it’s own, certainly not high fidelity, but kinda gritty and warm… The track is out now for stream and download (links below), hope you folks dig the track 🙂"

SEQtrak Bass Station Techno-funk!!

video upload by Jeremy Parker

"So I got my own Bass Station 2 now, and I'm enjoying it very much in combination with the Yamaha SEQtrak. I'm running the audio from the Bass Station into the SEQtrak input, so the Yamaha master effects (high pass filter and repeater in my case) can act on the Bass Station and really make everything sound cohesive. I'm 'borrowing' the SEQtrak sampler track (MIDI channel 11) for sequencing the Bass Station MIDI, which leaves my hands free to twist knobs and have some fun. Here's some techno-funk for your listening pleasure... :D Enjoy!"

Building a Full TECHNO Track With the RELIQ: First play with description

video upload by Starsky Carr

"I built an entire techno track using the Reliq hybrid control surface — sequencing CV, gates, and MIDI together. This is a quick preview before my full in-depth Reliq review drops, made for anyone who just wants to see what it can actually do in a real track.

In this short hardware jam, the Reliq's Breakout Module handles every CV and gate connection to my Eurorack rack, while its onboard LFOs and envelopes replace modules I'd normally need patched in separately — freeing up rack space while adding an extra oscillator's worth of movement. MIDI runs straight to the Dreadbox Artemis alongside it, all synced from the same sequencer. You'll hear polyrhythmic drum sequencing too — kick and closed hi-hat running full bars, snare on the backbeat at a different rate, and a 4-step open hi-hat loop sitting on the offbeats.

This is a fast, feature-packed look at the Reliq's matrix routing, CV/gate output, MIDI output, LFOs, and envelopes all working together in one musical piece — not a full walkthrough (that's coming soon), just proof of what one box can do.

What's covered:

Reliq Breakout Module: CV + gate patching into Eurorack
Onboard LFOs and envelopes standing in for extra modules
Simultaneous CV and MIDI sequencing (Eurorack + Dreadbox Artemis)
Polyrhythmic step sequencing across multiple tracks
Building a full techno track hardware-only, no DAW"

"A Juno-6 and DX7?"

"In this video I take a look at the AMY board: a tiny, affordable ($29) Arduino-based DIY synth module built around the open-source AMY synth library. It packs USB, an SD card slot, digital and analog audio, MIDI, and CV I/O into a board small enough to fit straight into a Eurorack case.

I go over what the board actually is and what's in the box, then jump into a MicroPython REPL to show how the AMY library's synth, voice, oscillator model works, patching up a simple sine voice, triggering notes, and using the built-in PCM/sample engine and tag-based sequencer to create a basic drum pattern. From there I install it in my Eurorack rack, run through the signal chain (MIDI in from the Hermod+, CV/audio out, self-modulation via CV), and share some closing thoughts on where it's strong, where it's limited compared to something like the Disting NT, and what I want to try next (serum-style bass patches with compression/distortion).

If you've got one of these boards — or you're thinking about picking one up — let me know what you're building with it in the comments.
