Released in 2001, Boss' SP-303 Dr. Sample was a digital phrase sampler and effects processor. The compact machine's affordability and ease of use made it popular with musicians and producers, including Four Tet, Madlib and the late J Dilla, who used the SP-303 to produce much of his final album Donuts.
Dr. Sample has now been discontinued, but those looking for a software-based alternative will be pleased to know that developer, producer and YouTuber Blezz Beats has taken inspiration from the SP-303 for a new plugin, Mr. Sample.
