Sequential Circuits Studio 440

The Studio 440 was a sampler sequencer and workstation manufactured by Dave Smith's Sequential Circuits (SCI) and released in 1986. The sampler's core is similar to that of the Prophet 2000 and Prophet 2002 [3], however, instead of a keyboard, the Studio 440 used a drum machine format and included a sequencer. The 440 also made it easier to access the full 512kb of memory available, to create samples as long as 12 seconds. Like the Prophet 3000, the Studio 440—and many of Sequential's products—lost sales due to the brand loyalty demanded by its competitors, including Akai Professional, Roland Corporation, and Korg.
