The Akai S950 is an expanded version of the S900 sampler, released in 1988 alongside the higher-end S1000. It took over some of the S1000's improvements, including time-stretching, and raised the maximum sample rate to 48 kHz. Like the rest of the S900 series, it can loop a sample alternating forwards and backwards, which the S1000 series cannot. Akai has discontinued it.
The ASQ-10 is a sequencer-only instrument. It has no sound generation. It does not sample. It exists solely to trigger, time, and lock external gear. Its design enables rhythmic complexity unplayable by hand — then corrects timing drift across the chain. It is the first MPC-shaped workflow, before the MPC existed.
The MPC1000 delivers the MPC workflow in a smaller, cheaper, more portable form. It adds six outputs, built-in effects, and memory expansion over the MPC2000 — while storing samples as WAV and sequences as MIDI on CompactFlash. Build quality is reduced, but sound quality is preserved. It is a sampling and sequencing instrument — not a synth, not a DAW, not a controller.
The MPC2500 upgrades the MPC2000 with 16-bit/44.1 kHz sampling, individually adjustable pad sensitivity, and the Grid editor — but keeps 64-track sequencing, 32-voice polyphony, and no automated effects sends.
The Akai MPC4000 is a 2002 hardware sampler sequencer built to lead the hardware sampler category. It has 16 velocity- and pressure-sensitive pads. It performs 96 kHz 24-bit sampling. It has 16 MB of sampling memory, upgradeable to 512 MB. It includes IDE bays for installing an internal hard disk drive and CD-ROM drive. It supports optional plug-in boards including Effects, ADAT, S/P-DIF & wordclock, and 8 analogue outputs boards. It has 2 MIDI inputs and 4 MIDI outputs. It was released in 2002 with the intent to lead hardware samplers.
The MPC500 is Akai’s entry-level sampling sequencer—a portable, self-contained beat-making station built for quick capture, arrangement, and performance.
The Akai S1100 is a sampler. Its name appears in alternate forms: 's1100' and 's 1100'. No technical specifications are available. Nothing else is confirmed.
The Akai S6000 is a 1999 rack sampler. It supports up to 256 MB RAM, optional SCSI hard drives, virtual hard disk sampling, and remote operation via detachable RS-232 screen. Its 26 filter types and extensive modulation routing enable synthesis from single-cycle waveforms. OS 2.14 resolved major bugs in OS 1.0. It includes a large built-in sound library.
The Akai S700 is a 1987 rack-mount 12-bit sampler derived from the X7000 keyboard model. It samples mono at 4–32 kHz, holds up to 8 seconds, but at 16 kHz allows only six 0.8-second samples. It offers 6-voice polyphony, non-resonant low-pass filtering, and QuickDisk storage. It is user-friendly but rigid: no stereo, no resonance, no modern file support, no workarounds.
The Akai XR10 is a budget drum machine released in the early nineties. It plays fixed PCM drum sounds from ROM. It has four modes, no backlight, no MIDI Thru, no internal amp or speakers. It is simple, stable, and silent until patched out.
The Akai S3000XL is a 16-bit sampler released in 1995. It has 32-voice polyphony and 2 MB of built-in RAM. It loads samples via a 3.5" floppy drive or SCSI-connected devices. Its large screen and intuitive interface enable quick and in-depth sample editing. Akai discontinued production and support, but many working units remain in studios worldwide.
The Akai S900 is a 12-bit sampler introduced in 1986. It supports up to six active samples simultaneously. Its firmware became upgradable via floppy disk from version 1.2. It features alternating forward-and-backward looping — a capability absent in the later S1000 series. An expanded variant, the S950, followed in 1988.
The Akai S3000XL is a 1995 sampling instrument with 32-voice polyphony and 2 MB of RAM. It features a large screen and intuitive interface for fast sample editing. It loads sounds via a 3.5" floppy drive and SCSI port, and plays back MIDI files for live triggering. Akai discontinued it in 1995. It belongs to the S3000 series, which succeeded the S1000 series and offered optional CD-ROM.
The S612 was Akai’s first rack-format digital sampler — 12-bit, single-sample, one-second max at 32 kHz, loaded via external Quick Disk drive. It defined the form factor and affordability threshold for what followed, but offered no polyphony, no internal storage, and no upgrade path.
The MPC60 redefined beat-making by collapsing sampling, sequencing, and performance into one hardware instrument. Its strength is immediacy. Its weakness is inflexibility.
The Akai S1000 was a 16-bit stereo digital sampler released in 1988. It offered CD-quality sampling, 24-bit internal processing, digital filters, effects routing, and early timestretching. It read CD-ROMs and wrote to SCSI hard disks. Its timestretching was crude but sonically distinctive—used on 'Higher State of Consciousness' and 'RipGroove'. It displaced the S900 as the studio standard.
