AlexBallMusic Unearths Korg’s Forgotten Music Computer

AlexBallMusic dives into a peculiar corner of Korg’s history, showcasing the long-lost MU-5000 sound module. Discover the abandoned 1985 music computer system, its crusty 80s charm, and why it faded into obscurity.

Blast from the Past: Korg's Lost Relic

Alex, from AlexBallMusic, opens the video with an intriguing introduction to a piece of synth history that many likely overlooked, the MU-5000 from Korg. This elusive sound module, part of a music computer system from 1985, was recently found in Italy after decades in obscurity. With typical British wit, he notes the importance of examining both a company’s triumphant successes and their abandoned failures to truly understand their history. This sets the stage for an exploration of how this peculiar relic fits into the broader narrative of Korg’s evolutionary timeline.


The MU-5000: Tech Specs and Embracing the Crunch

Delving into the technical side, Alex takes us through the intriguing specifics of the MU-5000. He points out that the module is 16-part multi-timbral and capable of some basic MIDI functionalities, but with a catch – the sound fidelity is notably low. Two enigmatic MS-6236 chips paired with DAC ICs power the module, alongside a BBD-based chorus generator. Despite its novelty, it lacks filtering, differentiating it from the DW-6000. Korg’s attempt at sonic adventure is evident in its simple yet effective design. In his characteristic style, Alex doesn’t sugar-coat his analysis: the drum samples have a lo-fi crunchiness reminiscent of old, cheap home keyboards, featuring a ‘crusty charm’ that feels distinctly mid-80s. The flaws are apparent, yet the module possesses an undeniable, gritty allure that makes it worth a listen, especially for those intrigued by the period’s sound exploration.

Chasing the Vapor: Musical Nostalgia

The MU-5000’s sounds are a nostalgic echo of the mid-1980s, full of crackle, hiss, and endearing imperfections from an era when digital samples were still finding their place. Alex plays through various programs, delighting in their inherently noisy, low-fidelity charisma—a stark contrast to more polished modern sound modules. He acknowledges that, while these are far from the most pristine sounds, they evoke a kind of beauty in their raw, untamed nature. It’s the charm of the half-broken toaster at a punk gig – raw, unapologetic, and full of attitude.

Why was this Tech Left Behind?

The answer to why the MU-5000 and its associated system were abandoned lies shrouded in mystery, partially due to still-active non-disclosure agreements from Korg. Despite digging deep and reaching out to Korg and other contributors, Alex is left with theories rather than facts. He speculates about logistical challenges affecting the collaboration with Epson on the MC-4000 computer component as a possible culprit. Additionally, the rise of competitors like Roland, who continued developing desktop sound modules leading to notable successes, further overshadowed Korg’s ambitions. This speculative journey into what could have been looms large in providing context to Korg’s evolutionary narrative – a glimpse at the path not taken, underscoring the volatile nature of synth development and marketing strategies during the 1980s.

Final Notes: A Forgotten Legacy Resurfaces

In closing, Alex expresses his gratitude to those who helped uncover this piece of lost history, including Riccardo Pietroni and Korg Japan. While the complete system was never fully realized or preserved, the MU-5000 offers a small window into a bygone era. Alex has immortalized its forgotten sounds through a sample pack available to his Patreon supporters. Despite some elements remaining a mystery, the MU-5000’s discovery prompts a re-evaluation of Korg’s legacy, inviting us all to appreciate even the unsuccessful and unfinished chapters in musical innovation. It’s a tale of what almost was, a testament to the eclectic journey of music technology over the decades.
