edit TECH main core based on a 8-bits Zilog Z80 (A) manages 6 channels polyphony, DACs are based on BA9221. The s700 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).
NOTE: memory is not dynamically allocated resulting in same amount of RAM for each sample.

 

edit SAMPLE the s700 monophonically samples at 12 bits resolution with adjustable bandwidth rates from 4 to 40 kHz.

12 bits

S700 sampling data:

frequency: time: response:
4 -> 40 kHz 8 -> 0,8 s 25 Hz -> 16 kHz


edit 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).

 

 

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:

akai s700 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 S800 LFO modulates only the pitch as a classic vibrato.
