"Oberheim SEM Pro Analog Synthesizer w/ Original Box - Signed by Tom Oberheim - Rare!

Excellent Near Mint Condition

One very small, faint scratch on the upper right corner of the black, right side panel as shown in photos. Generally not noticeable unless really looking for it at just the right angle.

Sounds Fantastic!! Plugin replicas do not do this synth justice in my opinion.

Includes Original Box, Power Supply, Manual, and a couple of Patch Cables"

Bad Gear - 80s are for NERDS!!!


video upload by AudioPilz

"Welcome to Bad Gear, the show about the world’s most-hated audio tools. The 80s are oftentimes associated with Hollywood-worthy heroism, impeccable style and epic synth music that aged great - as long as it was played on instruments designed in the 70s.

Today, however, we are going to talk about K4. This digital synth , Kawai’s answer to Roland’s answer to Yamaha’s DX7 and more upscale successor to the K1 demonstrates impressively that the 80s were - first and foremost - VERY, VERY nerdy.

"In this video, we take another look at UTF-8 SAMPLIFIED – the fully open-source 8-bit Eurorack drum module I released with ASCII Synth. It’s made its way into racks all over the world, and even into DIY workshops like the one run by mzourack at Noise Kitchen in Prague.

Now it’s getting even better:

Thanks to a pull request by community member poetaster, three new kits have been added: 808, Jungle, and Beatbox – plus a handy wav2c.py script that lets you convert your own samples into custom kits!

We built a 5 BAND VOCODER at Joranalogue Audio Design HQ


video upload by BRiES

"This idea was stuck in my head for at least a year before I finally decided to just ask Joran (‪@joranalogue‬ ) what he thought of the concept of building a vocoder using his modules.

The result is a crude 'proof-of-concept' 5 band vocoder that sounds a bit crap, especially on live vocals, but nonetheless it was a fun learning experience. I would like to repeat this educational endeavour for other ridiculous builds.

I realised afterwards that I should have documented the build process a bit more, explaining why certain choices were made. Maybe I can figure out how to logistically approach that for a next build. Looking forward to that.

Thanks to Joran and Frits at Joranalogue Audio Design HQ for having me, for providing a smörgåsbord of modules and for putting up with my relentless questions, jokes and general ADHD vibes.

Also: awesome video room amirite?!"

Moog Sound Studio & spices


video upload by No Lake

"Robert Arthur Moog was an American engineer and electronic music pioneer. He was the founder of the synthesizer manufacturer Moog Music and the inventor of the first commercial synthesizer. His inventions changed the complexion of the pop and classical music worlds. Moog synthesizers are considered high-quality instruments with a strong reputation for sound and build quality. They are known for their distinctive analog sound and are often praised for their musical legacy, solid construction, and the ability to inspire creativity.

video upload by RolandChannel

"A TR-808 beat so raw it stopped gangsters in their tracks."

"Check the debut of The Rhythm Creators series, featuring @ThEgyptianLover's first meeting with the drum machine that changed everything. Animated by Vaughn Taormina."



Press release follows:

Los Angeles, CA, August 7, 2025 — Roland Corporation celebrates the 45th anniversary of its iconic TR-808 Rhythm Composer today. Since its debut in 1980, the TR-808, commonly known as “the 808,” has shaped the creation of musical genres from hip-hop to techno, trap, and beyond. Its unmistakable sound has powered decades of iconic tracks, from smash hits like Whitney Houston’s “I Wanna Dance with Somebody” and Beyoncé’s “Drunk in Love” to a sea of underground techno, electro, and hip-hop anthems. TR drum machines have laid the musical pulse for generations, fueling global rhythm culture through the hands of producers, DJs, and creative visionaries who continue to push its legacy in new directions.

To celebrate this 808 Day, Roland will unveil a series of special releases—including a limited-edition sneaker collaboration with New Balance—and global events that pay tribute to the 808’s enduring legacy and cultural impact.

Rhythm Creators
As part of the celebration, Roland is launching The Rhythm Creators, an eight-part animated video series highlighting untold stories from artists shaped by the legacy of its most iconic rhythm machines—the TR-808 and its influential successor, the TR-909. Each episode blends humor, reverence, and nostalgia, and features stylized animation by Detroit artist Vaughn Taormina and narration from the artists themselves.

Episode one premieres today with Egyptian Lover, with new installments featuring Prince Paul, Fatboy Slim, Soul II Soul’s Jazzie B, and other trailblazing artists dropping throughout August and into September.

New Balance Collaboration
Roland and iconic footwear brand New Balance have relaunched the special edition Tiago Lemos NM808 x Roland sneaker. This collaboration exemplifies the 808’s impact on music and culture, showcasing the unique intersection of skateboarding, hip-hop, and fashion.

To further celebrate this collaboration, Roland and New Balance are hosting Atlanta’s creative community for an exclusive industry mixer dedicated to the 808’s legacy in the birthplace of trap music.

The mixer will be hosted at SESSIONS Atlanta, the iconic studio run by legendary producer Tricky Stewart. Highlights will include private Roland product demonstrations, live performances by Sonny Digital and Mix Master David, as well as an appearance by the popular BackTrack podcast host Don Cannon. Guests will also check out the Tiago Lemos NM808 x Roland sneakers in person.

POLYGENE II - First Look


video upload by LA Priest

"Sound recorded directly from the back of the synth (No added effects / eq / reverb etc)."


"POLYGENE II is an all analog polyphonic synthesizer with two halves. One half is all-transistor class A from signal source through audio path two output, the other half is identical except it uses analog chips to generate dynamic customisable waveforms.

Inspired by the earliest polysynths of the 1970s, it is fully polyphonic (all 24 notes can be played at the same time), can be tuned to any scale or tuning, is multi-timbral and completely touch sensitive.

Touching any part of the synthesizer bridges connections in the circuitry and creates a unique sound.

Patch & Play: Moog Minimoog Model D - Episode 1


video upload by William Cas

"In this episode of Patch & Play, William Cas explores the Moog Minimoog Model D (2016 Reissue), a faithful recreation of Moog’s iconic monophonic synthesizer, renowned for its rich analog tone, classic three-oscillator architecture, and expressive filter—revered across genres for its warmth, power, and playability.

Patch & Play is hosted by William Cas, featuring a new setup each series of episodes. The experience itself unfolds as a meditative dialogue with the environment, exploring its unique alchemy of sounds.
