"The Akai S900 is my favourite toy at the moment. I really like it very much - that and the Mac, they're a good pair. I did the whole Swimming to Cambodia score, the Jonathan Demme film, with one drum hit for the entire percussion sampled into the Akai, and it sounds like 50 different things. It's a lovely drum with a lovely sound to it, so I goofed around with it a bit and that's all there is. I don't think you'd ever suspect that it's just that one hit."more
""There are three sound sources", he explains. "There's an Akai S900 which has samples transferred from the Fairlight Series III, a Roland Super Jupiter and a Roland MKS20 piano module. All of those go into an Akai MIDI mixer and through two effects: a Yamaha SPX90 and an Alesis Midifex. They're all mapped by a Cooper Electronics MIDI Link, and I play them from a KX5 slung round my neck and a couple of Yamaha pedals. They put out program numbers to the MIDI link and that sends out separate program numbers to everything else. In other words I'll build up an entire patch with sound sources, a mix, effects and a stereo output, and store it. Then, when I send one program number into it from either the keyboard or from the pedal, it'll send the appropriate numbers out."more

I acquired my S900 from the then manager of Swan Yard Studios just as they were closing back in 2002, it had been used on countless recordings in the 80's and 90's along with an Oberheim Matrix 6r i bought and an Oberheim DPX-1, none of which i own today. The S900 was very similar to a later S950 i owned from what i can recall.
