TECH 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.
STRUCTURE: 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
- loop mode (with crossmode, hold and loop tuning)
- timestretch from 25% to 2000% with two analyze modes: cyclic or intelligent hear cyclic
SAMPLE IMPORT 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.
||Each Keygroup features edit parameters:
- Midi channel assign
- keyboard zone assignment
- EG amplitude
- LFO settings
- filter cutoff amount
- volume gain
- velocity switch.
PERFORMANCE the s2000 handles 16 parts each with individual functions:
||- 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 a 2-poles resonant digital dynamic low-pass filter.
Keyboard track filter at 1 octave range.
ENVELOPE there are 2 EGs with available preset templates:
- EG1 amplitude with 4-segments ADSR + 1 Hold time
- EG2 filter ADSR + 4 times
The special KEY SCALING allows to control the amount by which the key position affects the decay
and release rates.
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:
|Modulation wheel CC#1
assignable Midi CC (breath / foot / volume)
LFO 1 depth
LFO 2 depth
LFO 2 rate
- 255 samples
- 254 programs
sampling 2 Mbytes factory, expandable to 32 Mb using standard 72 pins SIMMs (no parity).
NOTE- the s2000 board is quite similar to 3000 board

STORAGE floppy disk drive format 3.5 DD/HD 1440 /720 Kb capacity with auto-boot.
FS: Floppies formatted in Akai proprietary file system: S2000 is not directly Ms-DOS compatible.
HD: It is possible to link a standard zip disk100 mb or some old HD (max partition 500mb) - too bad s2000 is often incompatible to most CD-ROM player models.
USB: it is possible to replace old FD with more modern USB reader.
MODIFICATION Some s2000 SCSI modifications are available, also common circuit bending process

EDITOR most common S-2000 editor was the free MESA (needs ISA / PCI SCSI card) also these:
- NICEWAVE (PC)
OPTIONAL EXPANSION BOARDS:
||FMX 008 rare flash memory
||IB-304F second filter ADD 1 filter EG ADSR
||IB-208P 8 outs + SPDIF out coaxial
||EB16 effects board-multi-effects processor 2 channels distortion, four-band EQ, ringmodulation, chorus, phase shift, flanging, pitchshift, autopan or rotary speaker, stereo delay and reverb .
