Sampling Keyboard (1986)
First Akai keyboard sampler from after the release of module model s612.
The X7000 is a big sampler old school machine with 12 bits resolution and tiny memory.
KEYBOARD 61 keys keyboard with velocity and aftertouch.
Main panel features a 16 x 2 lines backlit LCD, a data encoder, 30 push buttons, 1 slider for main volume and 2 wheels for pitch and LFO modulation.
Rear panel terminal connectors:
main signal out + headphones
LCD contrast trimmer
- switch for master keyboard function (no signal out)
- Midi interface
sustain pedalswitch input
program UP pedalswitch input
- record pedalswitch input (can be used also to trigger a sample)
- special Akai voice connector
- line and Mic inputs (with gain trimmers).
TECH main core based on a 8-bits Zilog Z80 manages 6 channels polyphony.
STRUCTURE the X7000 is able to sample up to 6 sounds that can be assigned to a singles patch with assignable split points, useful to create drum kits or multisampled instrument.
Sampled sounds are assigned to voices, then each samples has some special edit functions:
- transpose pitch
- pitch tune
- backward play
- drum play (EG does not end at retrig).
memory is not dynamically allocated resulting in same amount of RAM for each sample.
SAMPLE the X7000 monophonically samples at 12 bits resolution with adjustable bandwidth rates4->40 kHz (check out the table below).
Samples can be edited with classic functions e.g. overdub, resample, trimmer/cut,
loop point (forward, backward or alternate)
automatic splicing function automatically finds the best loop point (sometimes).
|from 4 to 40 kHz
||from 8 to 0,8 s
||from low 25 Hz to 16 kHz
SAMPLE IMPORT It is possible to import / export samples by Midi, but the process is not compliant to standard SDS sample DUMP.
EXPANSION there are 2 optional boards available.
- SXM007X battery backup system for memory
- ASK-70 increases number samples to 16 and memory about 512 kb (not sure).
PERFORMANCE system manages up to 6 indipendent parts with some functions:
- monophinc modes (x2)
- LFO to aftertouch
midi channel assign
- volume gain.
LFO a single delayed triangle modulator with 99 scaled intensity/depth values.
The X7000 LFO modulates only the pitch as a classic vibrato.
ENVELOPE 2 EGs (only release segment) and 2 destinations:
- EG1 amplitude
- EG2 filter cutoff.
FILTER non-resonant filter based on a MF6CN a switched capacitor VCF a kind of an hybrid analog-digital offers -12dB/ Oct. slope. The filter can be assigned to velocity and features a simple Keytrack function.
- 32 programs
- 256 kb sampling RAM
- 2.8" quick disk storage (64 KB x 2).
Tech: spotted some IC memory mn41464.
EDITOR not much on modern platform:

MAINTENANCE a common problem is the replacement of the quick disk belt.
