S900 tech specs
The S900 was a sampler released by Akai in 1986.
For most musicians in the 1980s, the Akai S900 was the first remotely affordable multitimbral sampler. It wasn't just another instrument you'd add to the mix, it was something you'd combine with a MIDI sequencer and mixing desk to make an entire studio in its own right. Combined with an Atari ST running Creator or Cubase, this was the start of the sound-first workflow. It helped house and hip hop producers segue from DJing and turntablism to creating full remixes and collages.
On a technical level, the S900 occupies an interesting middle ground: recent enough to be multitimbral and thus the cornerstone of a studio; yet old enough to actually change the playback sample rate in the DAC, rather than faking it in software while keeping the DAC at a steady rate.
Put it through the S950 then stretch it, to create the great type of shit to fit

Three years later, Akai released the S950. This was a minor improvement on the S900, bringing it cosmetically inline with the then-new S1000. Its memory could be increased to a more comfortable amount, and it gained the S1000's most prominent feature: timestretching. Like the S900, it can still perform pingpong loops, something the flagship S1000 can't do. It also improved upon the S900's sample rate, although that was already more than sufficient to begin with.
On "Voodoo [Ray]", you can hear a girl called Nicola singing. We went into a studio in Manchester called Jonny Roadhouse and she sang everything normally and I put her voice into the S950 and reversed it.
— Gerald Simpson (A Guy Called Gerald), 1989
As far as sampling's concerned, there's an Akai S900 for the sequencer sounds — that is, all the shorter samples that are rhythmical or have to be triggered repeatedly by the sequencer: percussive sounds and sampled basslines, things like that. Then we have the S950 which is used for all the keyboard triggered parts, which are the most prominent samples on the record. And that's it, really, but I'm very happy with what we've got. The samplers in particular have been brilliant. Everything's so easy on them, even the S950. They have some brilliant functions, and it's all, basically, pretty obvious. They seem to work in the same way that people's minds work.
— Mike Edwards, Jesus Jones, 1990
The vocal sample on "Playing With Knives" is timestretched — about 83%, I think.
— Carl Turner, Bizarre Inc, 1991
If you want drums tight then get an S950, S900, or any Akai sampler. The S1000 isn't as tight as the 950, but it's still good.
— Gamble, Rhythmatic, 1992
There's even an argument about Akai S950s and S1000s: some people think that when you play a 950 sample in the S1000 it loses its character. That's why a lot of people do a basic loop on the S1000, and when it comes to the bass drum and snare, they put them over the top on a 950. It has a snappier, brighter quality.
— Jimi Goodwin, Sub Sub, 1993
The S900 was fairly rudimentary. The S950 you could and still can do pretty much anything you want.
One of the reasons I stuck with the 950 rather than moving onto an S1000 was it had reverse loop and it was much easier to get a smooth loop because it becomes like a vibrato warble rather than a click click click. You could just move the loop point fractionally by millionths of a second until it sounded right.
— Norman Cook (Fatboy Slim), 2017
My two favorite instruments in the '90s were the samplers from Akai: S950 followed by S3000. I could use these almost blindly. The lowpass filter on the S950 is so unique that I acquired another S950 on the used market this week. The filters are the most important part of all the instruments for me.
