Boss SP-303


The Boss Dr. Sample SP-303 is a discontinued digital sampler from Boss, based upon the Roland MS-1 Digital Sampler and Boss SP-202 Dr. Sample. The SP-303 was revamped and redesigned in 2005, and released as the SP-404, by Roland Corporation.

Features

While the Dr. Sample SP-303 may lack some of the features seen on other hip hop production samplers such as the Ensoniq ASR-10, the Akai MPC, and later SP installments, it however has many other unique features that make up for that. Like the SP-202, the SP-303 utilizes 8 pads, 4 soundbanks, and an external mic.
The sampler provides up to three minutes and twelve seconds of sampling. The sample time can be expanded by the use of SmartMedia cards. The SP-303 features twenty-six internal effects that can be applied to samples and external sources as well. Some of these affects are Filter + Drive, Pitch, Delay, Vinyl Sim, Isolator, Reverb, and Tape Echo. Another notable feature is the built-in pattern sequencer, where loops and patterns can be programmed.

Musicians

The SP-303 is often praised by various musicians for its unique sound qualities. Frequent SP-303 and 404 user Dibiase said of the sampler, "The difference between the 303 and SP-404 is that the vinyl sound compression sounds way different in the 303. It has a grittier sound."
The sampler has often been used live and in the studio by artists such as Animal Collective, Panda Bear, Four Tet, Madlib and J Dilla. Dilla famously used only the SP-303 and a 45 record player to create 29 of the 31 tracks from Donuts while hospitalized. Madlib produced most of the collaboration album Madvillainy, by using a Boss SP-303, a portable turntable, and a cassette deck. This including beats for "Strange Ways", "Raid", and "Rhinestone Cowboy", which were all produced in his hotel room in São Paulo.
