video upload by oak sampler

Meet the upcoming "OAK-S37 Sampling Workstation" keyboard synthesizer.

Playlist with additional details:

1. OAK Sampler Sound Playback and Effects Test
I absolutely love the ASR-10. I’m building a new hardware workstation inspired by the ASR-10 that runs the original OS , effects etc and replicates the HW in a modern form. There will be some updates on the project. This is the boot and general test. Potato speaker recording. #asr10 #90ssampling
2. OAK Sampler (ASR-10 in Hardware) Sequencing & Sample Editing
I love the ASR-10. I’m building a new hardware sampler inspired by the ASR-10. It can run the original Ensoniq ASR-10 OS and effects algorithms. This video shows sequencing and sample editing on the OAK Sampler.
3. OAK Sampler (ASR-10 in Hardware) vs ASR-10 Sound Comparison
This video compares the OAK-S37 and an the ASR-10 using the same sequence, individual samples, filters, envelopes, and effects.

I recreated “93 ’til Infinity” as a test project using identical files across both systems.

I intend to do a limited first run eventually (no dates yet).

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"

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."

"Really wanted something OP-1 sized but more performance focused (and cheaper), so i made it myself. It runs on AMY, i've currently added the built-in patches and implemented a BLE MIDI keyboard mode, later will start adding my own instruments.

Originally planned to use korg nanokey2 as the keybed, but the feel was so bad that i had to switch to low-profile mechanical key switches.

Overall extremely happy with the result, especially given that it's my first big electronics project"
