The SP-404 is new from Roland - a little sampler with built in effects and sequencer, a bit like a tiny Akai MPC. It replaces the well-recieved SP-303 (here is a nice shot of Saul Williams' DJ playing live with just a SP-303 and a CD walkman), and revives a couple of features that were on the original SP-202 - battery power and a built in microphone for lo-fi on-the-go sampling. No price yet, but should be around £300. (via GearJunkies)
UPDATE: My geek powers failed me, and I missed the most crucial part of the story. Over to Drew: "Holy crap, Roland finally made a 404! For those that don't know: Roland made the famous x0x machines in the 80's - there's a 101, a 202, 303, 505, 606, 707, 808, 909... but no 404! The reason was that the Japanese word for 'four' and their word for 'death' are very similar - four is considered an unlucky number, like 13 in western society..."
