Linn 9000 (1984)


Rare digital drum machine really ahead of its time but bugged by many OS troubles and technical issues.

Note: this page is relative to original machine and not to third-part upgrades, also some of these pictures may differ from the classic 1984 edition.

one the most unreliable and buggy machine ever mad: in fact this ground-breaking and expensive project litteraly bankrupted the Linn company. It is hard to list all possible issues, but the most common and dangerous is still the battery leakage.

REVIEW: "The Linn 9000 is a nightmare for maintenance, but it sounds really good. For collectors or technical geeks"

Thanks to Alessandro Petrini

The Linn 9000 is a dream I’ve had for a long time. It answers nearly all of the requests I’ve received from top recording artists over the years. To a far greater degree than has existed before, it allows the non-technical artist to quickly and accurately realize the music which exists in his mind.- Roger Linn
