X1L3 - ALLEYKAT - DEV - NINE LIVES - NO REGRETS - module test build - swinsid - eurorack module

video upload by X1L3

The ALLEYKAT gets a front panel.

"First and flawed test build of the Alleykat module.
Nine lives - no regrets......

Completed the next schematic revision today ready for submission to fab. In doing so i ended up spending an hour on this flawed test piece knocking this up for a bit of fun.

When you consider how good it sounds (in a c64 kind of way) in it's current state, it becomes quite obvious how cool it will be when the filter is online and all the parameters are active. The test boards had numerous errors on them which have rendered the ring/sync and octave hopping inactive. The filter cutoff and resonance were also mis-routed in the schematic which rendered the filter unusable.

Swinsid in circuit this time. Does a decent enough job, but i've yet to see how it performs in comparison to a real SID or a superior clone when the ring/sync and filter come into play. The only difference i hear using just the waveforms and pwm compared to the usual 8580 i use for testing is that the swinsid doesn't sound as bright.

With a bit of luck i've fixed everything that was wrong with the first attempt and the next revision will work properly."

Best Ambient Synth Shootout #151: SammichFM - Song 3

video upload by Christian's Sonic Spaces

"This is the third recording with the SammichFM. It is a streamlined, compact version of the MIDIbox FM synthesizer DIY kit. Designed around the OPL3 chip YMF262 (4-Operators with 4 different waves), which was a famous sound chip from the 8 bit computer era (e.g. Sound Blaster 16 soundcard), it can play 4-sounds with 6-voice polyphony each.

I used for the recording the following FX pedals:
Red Panda Raster 2, Pigtronix Echolution 2 Deluxe, GFI System Specular Reverb 2.

The signal went through a Presonus StudioLive 16.0.2 into the PC via USB for recording. To create the complete song I recorded consecutively several stereo tracks. On some tracks Compressor and EQ where added in Cubase 13. The final song was then mastered using iZotope Ozone.

Well, I decided to go back to the basics, but at the same time make something useful for the synth community and do a kind of competition (I like competitions;-). What's my best synth for ambient music :-)"

Roland Future Design Lab and Neutone Advance Project LYDIA with Phase 2

video upload by matrixsynth



Press release follows:

AI‑powered neural sampling evolves into a more integrated, performance‑ready hardware concept, debuting at Superbooth Berlin

Berlin, Germany, May 7, 2026 — Roland Future Design Lab (Superbooth B023 & B026), the forward‑looking research division of Roland Corporation, and Tokyo-based AI music technology company Neutone today announced Project LYDIA Phase 2, a refined evolution of their experimental AI‑powered neural sampling pedal concept. Shaped by months of direct feedback from musicians, developers, and live performers, Phase 2 moves the project closer to a fully self‑contained, performance‑ready hardware platform.

Project LYDIA Phase 2 builds on the technology preview first unveiled in November 2025 and will make its public debut at Superbooth Berlin (May 7–9), offering attendees hands‑on access to the latest iteration.

Phase 2: Integrated, Performance‑Ready, and More Expressive

Responding directly to feedback gathered through live demos, industry showcases, and global surveys, Project LYDIA Phase 2 introduces several key hardware enhancements:

Refined hardware design with enhanced flexibility, supporting easier Raspberry Pi 5 installation and standalone USB MIDI controller operation
Fully integrated audio I/O, eliminating the need for an external USB audio interface
Onboard LCD display for clearer navigation and real‑time parameter feedback
User Preset memories for saving control settings and more
MIDI connectivity for deeper control, automation, and integration with existing studio and live rigs

A Feedback‑Led Approach to AI Hardware Design

Roland Future Design Lab partnered with Neutone to introduce Project LYDIA as an open, public‑facing experiment: exploring how neural sampling could be embodied in a tactile, musician‑centered hardware format. The initial prototype quickly generated strong interest from many corners, prompting extensive dialogue about workflow, control, and musical expressiveness.

“From the very first demos with professional audio developers through the overwhelming response from musicians worldwide, it was clear that Project LYDIA was resonating,” said Paul McCabe, LA‑based leader of Roland Future Design Lab. “That dialogue directly shaped Phase 2. This version reflects what creators told us they want from AI hardware in real musical contexts, while also bringing forward new ideas from our team.”

Rather than positioning AI as a replacement for musicianship, Project LYDIA emphasizes augmentation and control, allowing performers to interact with neural models in immediate, physical, and musically expressive ways. The familiar pedal format places AI processing into a workflow many musicians already trust, bringing transparency and tactility to technology often associated with screens and abstraction.

This feedback‑driven development aligns with Roland’s broader commitment to responsible AI innovation, as outlined by AI For Music, the initiative co‑founded by Roland and Universal Music Group to establish ethical principles for AI use in music creation.

Debuting at Superbooth and Beyond

Project LYDIA Phase 2 will debut publicly at Superbooth Berlin, followed by appearances at Audio Developers Conference Tokyo in early June and select additional events throughout 2026. RFDL and Neutone will continue gathering insights from creators both in person and online to inform future iterations of the project.

Music creators interested in learning more or contributing feedback can participate in a new survey here.

ETCHES | Soundscape Palette by Puremagnetik

video upload by Puremagnetik


via Puremagnetik

"Etches is a layered soundscape synthesizer. It's a palette for playing with sound, sketching melodic sections and building evolving tapestries. It moves between cinematic washes, percussive pizzicatos, and atmospheres worn smooth through ambient processing.

Inspired by live modular techniques, Etches is built upon classic synthesis and tape music traditions. Etches’s main engine includes a complex oscillator, a splice recorder and built in space processing.

We designed Etches to be performed. Every control is on the surface, and every gesture is audible the moment you make it. There are no traditional envelopes or filters here. You shape the timbre as you play.

Pick a root note and choose from twelve scales and modes and the pads stay locked to that key while you move. It's hard to play a wrong note, which means you can focus on phrasing instead of finger positions.

At the center is a monophonic voice generator and a splice recorder with overdub, so you can layer sounds into something bigger than individual patches. An internal LFO moves against each splice, modulating where the recording starts and ends. It's a behavior we first used in our LAPS and JOTS pedals. Around all of that: a tape-style delay, and a stereo space processor you can get lost in.

Etches Features:
• Four articulation pads that control contour, timbre-shaping and animation
• Musical overdrive with soft clipping
• 80-second multi-splice recorder for capturing ideas and layering sounds
• Stereo space processor with tape-style delay and a pristine reverb.
• Stereo output
• Runs on a standard Boss-style 9V power supply"

This one was spotted and sent in via
M Me.

One was previously listed on Vemia.

"Modified Roland TR-606 / by Filippo Samore / TR-608 > as used by Hainbach on YT [posted here].
The TR-606 in 808 territory and beyond, with tuning, decay and tone mods.

' This Drummachine is on a another level and is a lot of fun (you become very creative) '

' The mod is high-quality and truly enhances the sound engine of the 606
without compromising its handy form factor. It is almost like a TR-808 now,
except maybe a little more interesting, because it is still a charmingly shuffling 606 at its core.'

Examples:
Visit the phunkydesk dot com Domain / > the files after the slash (/) are as follows:
608_BD.wav, Loop1.wav, Loop2.wav
(there is no distortion/overdrive or clipping converters!)

The main modification in this revisited classic is the complete redesign of the kick drum circuit
with a lot of borrowed technology from the 808!

+ Kick: Tune, env Control, tone and decay.
You can also send the kick through the second output separately!
+ The Kick can also have "almost infinite" decay

+ Snare: same borrowed technology from the 808 but with an improved decay length.
It gives access to tune, snappy and decay.

+ L.H Toms: Tune independent from each other and cuts out the annoying noise present in their circuit.

+ Hi-Hats: Tune and decay, separate for both open and closed hats


++ Original Roland TR 606 carrying case
++ Device is serviced (while Mod)

++ Device checked in endurance test

ESP32-S3 PolySynth - Work in progress

video upload by Bad Dog Designs

"This is a fully functioning Polysynth using an ESP32-S3 to model the audio in real time, from an initial single Sine wavetable calculated on power up. The control panels for the oscillators and common controls all use CAN bus to communicate parameter changes to the audio engine - rather than wiring up a lot of IO, it just sends a message like 'Change oscillator 3 to Sawtooth'

Basic spec so far:

6 oscillators in 3 pairs that have Sine / Triangle / Saw / Pulse / Noise and Chaos waveforms. There are then independent wave folding modifiers and Sample and hold modifiers. Each oscillator pair can also be hard sync'd to it's partner for mono use, or FM modulated.

Common controls have ADRS envelope control, High / Low / Band pass filter with Envelope and tracking control. Ring modulator and Play mode selector for Unison / Duo / Poly. 2 re-triggerable LFO's with delay.

Currently working on the routing section that will allow pretty well anything to modulate anything else stored as separate routes - up to 12 routes can be applied at once. Then patch storage and recall, and hopefully some nice analogue FX at the end.

In the clip, all the audio is straight out the back of the DAC with no processing or FX."
