edit VOICE main core based on a 8-bits Zilog Z80 manages 6 channels polyphony.
STRUCTURE: Up to 6 samples can be assigned to a singles sound with split point, useful to create drum or multisampled instrument. Sampled sounds are assigned to voices, and each samples has some edit functions:
- transpose pitch
- pitch tune
- backward play
- drum play (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 (check out the table below). Samples can be edited with classic functions such as: overdub, resample, trimmer/cut, loop point (forward, backward or alternate), in addition the automatic splicing automatically finds the best loop point.
SAMPLE IMPORT It is possible to import / export samples by Midi, but the process is not compliant to standard SDS sample DUMP.

 

12 bits

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 EXPANSION there are 2 optional boards:
- SXM007X battery backup system for memory
- Ask70 increases number samples to 16 and memory about 512 kb (not sure).


s700 memory board

 

editPERFORMANCE system manages up to 6 indipendent parts with some functions:
- mono mode (2)
- LFO to aftertouch
- midi channel
- gain volume.

akai s700 tech



edit LFO a single delayed triangular modulator with 99 scaled intensity/depth values.
The LFO modulates only the pitch (vibrato).


LFO




edit ENVELOPE
2 EGs (only release segment) and 2 destinations:
- amplitude
- filter cutoff.


EG



filter FILTER
non-resonant filter based on a MF6CN a switched capacitor VCF a kind of an hybrid analog-digital offers -12dB/ Oct. slope.
TIP: The filter can be assigned to velocity and features a simple Keytrack function.

OS latest operating system on EPROM - This OS needs to be booted by the quick disk system.
Here you can DOWLOAD the 1.6 version (untested).

LOFI GEEKS

REVIEW : "Strictly for old school sampler lovers :) Give it a try if you like grungy 12 bits compressed sound! just pay attention to delicate and obsolete quick disk system "
