video upload by Behind Designs

This one is in via John L Rice.

"WW2 & Cold war weapons and spy gadgets were truly amazing! Have you ever wondered about the history of RFID and how it works? It was originally developed and first used as a Soviet cold war spying device. The Thing or The Great Seal bug as it was known, sat on the wall of a US ambassadors office for 7 years completely undetected listening into American secrets. The technology behind this revolutionary device now resides in your pocket in the form of Radio Frequency Identification. or RFID. Thank you so much to everyone who has subscribed and supported the channel so far.

ARTEMIS, un polifónico ANALÓGICO compacto y completo

video upload by Hispasonic

"El buen sabor que acostumbra a dejar Dreadbox con sus analógicos está presente en el sintetizador polifónico Artemis, que ofrece seis voces sustractivas y las completa con 4 efectos para llegar, pese a lo compacto del formato en módulo, a sonidos a través sus salidas estéreo.

No habíamos traído a Hispasonic este modelo que recientemente ha pasado a estar disponible en tiendas, así que hemos aprovechado la visita a Superbooth 2025 para daros a conocer sus características y mostrároslo en acción en varios de los primeros presets de los hasta 512 que puede alojar internamente.

Googlish:

"The good taste that Dreadbox usually leaves with its analog synthesizers is present in the Artemis polyphonic synthesizer, which offers six subtractive voices and complements them with four effects to achieve sounds through its stereo outputs, despite the compactness of its module format.

We hadn't brought this model to Hispasonic, which has recently become available in stores, so we took advantage of our visit to Superbooth 2025 to introduce you to its features and show it in action with several of the first presets of the up to 512 it can store internally.

Zen Synth? Thinking through the Kodamo Mask1

video upload by j bowman

"Is the Kodamo Mask1 the most Zen-like synthesizer on the market today? In this video, we take a deep dive into the bitmask-based sound engine of the Mask1 and explore its groundbreaking approach to sound design on synths. Whether you're a seasoned synth head or just discovering the unique potential of the Kodamo Mask1, this video walks you through the philosophy, workflow, and sonic capabilities that make this synth stand out.

🧠 We'll unpack what makes the Mask1’s bitmask synthesis architecture different from traditional subtractive and FM synthesis, and why this could change how you approach creative sound design synth work. From clean digital textures to gritty harmonic layering, the Mask1 offers a truly original toolkit for crafting viral-worthy sounds.

Perfect for synth enthusiasts, sound designers, and anyone hunting for deep-dives into rare or underrated instruments. This isn’t just a review—it’s a journey through a meditative and highly programmable machine built for sonic sculpting.
