Sequential Circuits Studio 440


The Studio 440 was a sampler, sequencer, and 32 sound drum machine manufactured by Dave Smith's Sequential Circuits and released in 1986. The sampler's core is similar to that of the Prophet 2000 and Prophet 2002. There is a 3.5" floppy disk drive to store samples and data.

The 440 also made it easier to access the full 512kb of memory available, to create 12-bit samples from 12.5 to 33.5 seconds and up to 41.667 kHz.
