First Akai keyboard sampler from after the release of module model S-612.

The X7000 is a big sampler old school machine with 12 bits resolution and tiny memory.

edit

info 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 (it can be used also to trigger a sample)
- special Akai voice connector
- line and Mic inputs (with gain trimmers).

 

 

edit TECH main core based on a 8-bits Zilog Z80 (A) manages 6 channels polyphony, DACs are based on BA9221. 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 instruments.
Sampled sounds are assigned to voices, then each samples has some special edit functions:

CPu z80 - transpose pitch

- pitch tune

- backward play

- drum play (in this case the EG does not end at retrig).

editmemory is not dynamically allocated resulting in same amount of RAM for each sample edit




edit
SAMPLE the X7000 monophonically samples at 12 bits resolution with adjustable bandwidth rates from 4 to 40 kHz. 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 (at least sometimes).

Sampling frequency: Sampling time: Frequency response:
from 4 to 40 kHz from 8 to 0,8 s from low 25 Hz to 16 kHz





edit SAMPLE IMPORT It is possible to import / export samples by Midi, but the process is not compliant to standard SDS sample DUMP.

edit EXPANSION
there are 2 optional boards available.

x7000 memory board - SXM007X battery backup system for memory

edit ASK-70 increases number samples to 16 and memory about 512 kb.




editPERFORMANCE
system manages up to 6 indipendent parts with some functions:

x7000 tech

- monophonic modes flag (2 priority modes)

- LFO to aftertouch amount

- Midi channel assign

- volume gain amount


 

edit LFO a single delayed triangle modulator with 99 scaled intensity/depth values.
The X7000 LFO modulates only the pitch as a classic vibrato.

edit ENVELOPE 2 EGs (only release segment) and 2 destinations:

EG - EG1 amplitude

- EG2 filter cutoff




filter FILTER
non-resonant filter based on MF6CN a switched capacitor VCF a kind of an hybrid analog-digital offers -12dB/ Oct. slope.

filterThe filter can be assigned to velocity and features a simple Keytrack function.

REVIEW "Give it a try if you like grungy 12 bits compressed sound! if you don't have much room, you should maybe check out rack version S700 or the previous S612 with real-times controls."
