Description
The S900 sampler was Akai's first truly professional sampler, released in 1986. Its sampling specifications were pro-quality at the time: 12-bit stereo sampling, 7.5kHz to 40kHz variable sampling rates and a maximum of 63 seconds of sample time at 7.5kHz. Up to 32 samples can be created and stored to disk along with any edit settings. This was one of the first rack-mount samplers to use a built-in disk drive. Although the drive could load sounds while you play, it was still a very slow process.
AKAI S900 12 bit Rack Sampler Specifications: • Polyphony - 8 voices • Sampler - 12-bit linear, 7.5 - 40kHz sampling rates (63 seconds). • Memory - 750 kB RAM in S900 (not expandable) • VCA - ADSR • Control - MIDI

Source -
The Akai S900 is often paired with an MPC due to its lack of a built-in sequencer, making it reliant on external devices for sequencing tasks.

A certified classic!!!
Most are seeking the S-950, because of the time stretch feature, but what they don't know is the S900 is a secret weapon itself with it's digitally controlled analog filter. It also has an uncanny sound that works perfectly for drum and percussive sounds. I still use my S900 to give certain types of samples that dry 12-Bit grit. This is one sampler I will never let go...

Nice warm filter and easy to use
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.

Presented on Legowelt's official website, cited as being one of the pieces of gear used by Legowelt at some point.
At 3:50 Paul Barker, Al's righthand man back in the day details how the band used Akai S900 samplers in addition to the Fairlight CMI to write and record material for TLORAH. I'm putting this under both Al and Paul as they both presumably used the equipment together back in the day.
Per "Rock This Town" publication, special issue 1991:
NOTE: the article lists two Akai "S9000" samplers, but Akai has never used this model number for any product at any point in its history. Akai DID make the very-popular S900 sampler in this timeframe, so the extra zero has to be a typo.
In 1991, the setup was as follows: [Rock This Town special issue 1991]

You’ve joined the Philip Glass Ensemble in 1974. I guess the live rig has changed a few times over all these years. Could you share with us how your setup has evolved until the latest pre-Bidule setup?
When I joined, the keyboards consisted of 3 Farfisa Mini-Compact organs. That was it. Over the years of my involvement, the Ensemble went through a series of migrations to new hardware. The first was the replacement of one of the Farfisas by a Yamaha YC45-D dual manual electric organ, a wonderful machine with touch sensitivity and adjustable percussive attack. After that, we added an Arp Explorer synthesizer. Next came a Sequential Circuits Prophet 5, then an Oberheim OBXa, then a Yamaha Dx7 (one of the first in the US, hand-carried back from a tour in Japan), then an Emulator I sampler (serial #002), then a Roland Juno-106 and a Roland JX3P, and an Emulator II sampler, and then, as we adopted MIDI controllers and rack modules, a Roland Super Jupiter, a Yamaha TX-816 rack and a YTX-802, several Oberheim Matrix-6R. and a number of Akai S-900 samplers, later replaced with Digidesign Samplecell I cards running on Mac IIs.
In this photo it shows Dwayne Goettel in their studio with an Ensoniq ESQ-1, Ensoniq Mirage, E-Mu EMAX, Akai S900. There is an effects rack with a Lexicon PCM 41, a pair of Korg SDD-1000s. In the background is an Atari 1040ST running Steinberg Pro 24 sequencing software.
""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."
"By the time 'Floodland' was recorded, we had an Akai S900 sampler. Like manna from heaven. Most of the drums on 'Floodland' came via the Akai. The DMX toms were resampled from the drum machine and off tape. Resampled RX5 kick, snare and hats formed the rest of the skeleton crew. We've been creating samples ever since, but we don't collect much any more; one encounters the same old samples circulating the globe under different names. Some of them sound suspiciously like they've been sampled off Sisters records. It's been a long time since we changed one of the Doktor's standard voices. We've created and collected a lot of "special effects" drum sounds, but we don't use them live because the sound would vary too wildly from song to song. It's not a practical solution unless you have everything submixed with automation - or running off a tape machine, like certain electronic bands we know (and all of the very famous ones we don't know). They might as well just play the record. We like a bit of risk, and we like to be able to tinker with things from concert to concert. The Akai S900 is still a perfectly fine drum sampler. Its grainy sound can be an advantage."
At 3:50, Paul states how him and the rest of the band created and recorded much of TLORAH using a Fairlight CMI and Akai S900.
From the FAQ page found on The Enigma Archive: "From the credits of various albums, it is known that Michael Cretu uses or has used the Waveframe 1000, Audi Frame Workstation, MIDIMoog, PPG System, Korg M1, C-Lab Notator, Takamine 6 and 12 String, Tom Anderson Electric Guitars, Otari DTR-900, Akai 900, Linn 9000, Prophet 2002, X-Pander, EMS Vocoder, DX-7, and Roland Super Jupiter."
