Its a 12bit sampler from 1988 with a digital low-pass filter, keygroups, looping and timestretch. Great review here from Producers Edge.
http://www.producersedgemagazine.com/ar ... ais950.htmYou can pick up an S950 for the price on an MPC60 memory expansion, so a lot of people do just that. A stock S950 has 750kb memory, expandable to 2.25mb whereas a stock MPC60 has 750kb memory, expandable to 1.5mb. The S950 has the features that the MPC60 (and SP1200) lack which is why they are commonly partnered together for 12bit beats.
