Akai S-2000 (1995)
Midi Stereo Digital Sampler


A popular budget spinoff sample module from more expensive models S3000 / S3000XL with smaller display and lacking some functions.

Today S2000 is considered quite obsolete with a not-so obvious user interface. Now the module can be purchased for very low street prices.

info SAMPLER MODULE Main panel features a 16 x 8 backlit display, a data encoder, 2 knobs and 16 buttons.

Rear panel terminal connectors:
- main signal out + 8 individual output (optional board)
- Midi interface IN / OUT / THRU
- SCSI interface (25-sub)
- Digital I/O (optional board)

Front panel terminal connectors:
- headphones out
- stereo signal input (for sampling).



editTECH main core based on a 16-bits CPU NEC D-70236 manages 32 voices polyphony.
The stereophonic sampling engine works at16 bits resolution - DACis a PCM69AP Burr-Brown and ADC is a ASAHI KASEI AK5359 with 2 fixed recording frequencies: 22,05 and 44,1 kHz.


a single sample into the S2000 system OS can be modified with various edit functions:
- trim sample length
- tune sample pitch
- normalize amplitude
- reverse sample
- amplitude fade IN or OUT
- resample bandwidth
- loop mode (with crossmode, hold and loop tuning)
- timestretch from 25% to 2000% with two analyze modes: cyclic or intelligent demo hear cyclic

it is possible to Midi sample dump or import foreign Roland or EMU volumes (only CD/HD).


The S2000 is also retrocompatible with previous models S900 / 950 (sytem automatically converts from 12 to 16 bits- check out recording comparison in the demo section) or S1000, 1100, 2800, 3000 and 3200.


EDIT HIERARCHY a single or more samples must be placed in a keygroup and once mapped they make a program.

s2000 sample structure Each Keygroup features edit parameters:
- Midi channel assign
- keyboard zone assignment
- EG amplitude
- LFO settings
- filter cutoff amount
- volume gain
- velocity switch.



edit PERFORMANCE the s2000 handles 16 parts each with individual functions:

akai s2000 tech - Midi channel assigment
- stereo panning position
- analog out assignment (if optional IB-208P board is fitted)
- semitones transpose
- keyboard zone assign
- note polyphony priority
- monophonic legato triggering
- portamento - with rate and time modes
- Midi song import (up to 300 kb).

filter FILTER
a 2-poles resonant digital dynamic low-pass filter.
Keyboard track filter at 1 octave range.

adsr ENVELOPE there are 2 EGs with available preset templates:
- EG1 amplitude with 4-segments ADSR + 1 Hold time
- EG2 filter ADSR + 4 times

eg s2000

The special KEY SCALING allows to control the amount by which the key position affects the decay
and release rates.



lfo LFO 2 delayed modulators with variable depth and 4 shapes (triangle, sawtooth, square and random).
- LFO 1 generally acts as a standard vibrato or can be assigned to APM matrix
- LFO 2 is AUX and can be assigned to APM matrix.

APM MATRIX any modulation source may be routed to virtually any control input, summarized in this table:

Sources:   destinations:
Modulation wheel CC#1
Pitch bender
Pressure key
keyboard position
assignable Midi CC (breath / foot / volume)
LFO 1 depth
LFO 1 rate
LFO 2 depth
LFO 2 rate
filter cutoff


edit MEMORY:
- 255 samples
- 254 programs
- sampling 2 Mbytes factory, expandable to 32 Mb using standard 72 pins SIMMs (no parity).

akai s612 S-612 (1985) the legend started here

akai s900

S-900 (1986) cult sampler at 12 bits. Revamped with S-950

akai s700 S-700 (1987) upgrade version of S-612
also exists in keyboard version X-7000.
It seems that a model called X-3700 was a never-released prototype or a plain hoax.
akai s01 S-01 (1987) budget sampler, basic display no SCSI.
S-20 laptop version and Remix16 (and Japanese 88) with improved options and memory.
akai s1000 S-1000 (1988) 2nd generation cd quality and SCSI
S-1100 boosted model comes with many optional boards and HD recording.
S-1000KB is the S-1000 keyboard version
S-1000PB playback, just plain sample reader.
akai s3000

S-3000 (1996) 3rd generation.
- S3000XL was an update with extra (SCSI, digital)
- S2800 cut-down version
- S2800I with SCSI standard

thumb res s2000





OS S2000 requires to boot OS from floppy (or HD). Last one is 2.0, which should improve SCSI compatibility.

->we still have some spare 2.0 disk in stock

REVIEW "A lot of synth programming there, not a mere static sampler with advanced APM modulation like a true synth. Bargain price today"

manual manual
-cheap -display / edit
- flexible
-SCSI compatibility

"The S2000 is a high performance sampler offering nearly all the functionality of the original
S3000 and the new S3000XL but has a re-designed user interface "
