Akai S700

Akai S700 Image

Akai's 12-bit S700 was released in 1987 as a rack-mount spin-off of the X7000 keyboard sampler. The S700 is a very user-friendly sampler. It's much like the S612 that preceded it, but with some improvements. It has the same filters and effects as the S612. Its sampling frequency ranges from 4 to 32 KHz and it supports up to 8 seconds of sample-time. Its polyphony is limited at just 6 voices and unfortunately it uses the totally obsolete 2.8-inch QuickDisk format for loading and saving samples.

A unique limitation of its sampling, the S700 is capable of recording only six 0.8-second samples at its maximum bandwidth setting of 16kHz. It samples in mono and using twelve bits it has a distinctly lo-fi sound quality. Yes there's a low-pass filter and no, it's not resonant. So, limited memory, sound quality and data-storage may label the S700 as a dead end. But some think it's got character and continue to use them today. It's a dinosaur, and some people may like that about it!

15 characters num LCD (against 80 for the S900/950).

When released in 1987 price was 1400 $.

Bought mine during summer 2013 for 50 € (disk drive not used/tested).

There are some mistakes about this sampler on this page.

Filter is lowpass only. 12db.

Memory is not 128k but around 750k (according to Keyboard Mag and Sound on Sound). 128k is the limit of a Quickdisk.

Bandwidth you can select for sampling : 1,6khz, 1,7khz, 1,8khz, 1,9khz, 2,0khz, 2,1khz, 2,2khz, 2,4khz, 2,5khz, 2,6khz, 2,8khz, 3,0khz, 3,1khz, 3,3khz, 3,5khz, 3,7khz, 4,0khz, 4,2khz, 4,4khz, 4,7khz, 5,0khz, 5,3khz, 5,6khz, 5,9khz, 6,3khz, 6,7khz, 7,0khz, 7,5khz, 7,9khz, 8,4khz, 8,9khz, 9,4khz, 10khz, 11khz, 11.?khz, 12khz, 13khz, 13.?khz, 14khz, 15khz, 16khz

I ordered a replacement belt of the right dimensions here (with some help from Curtis! Cheers dude)

http://www.turntableneedles.com/Flat-Belt-Small-90-Inch_p_512.html

I'm thinking of posting a video of the replacement when I do it, should be the same as the famicom, only taking the drive out of the sampler will be different.

The problem the disk drive is most likely the belt. The QD disk system has a weak link; the rubber drive belt. If you are up for the repair, or want to take it in, you need a 9 inch by 2 mm replacement belt. Try and track one down at you local electronics repair store or this place says they will have some in January.
Rising Stuff The disc drives were also used in an ancient ninetendo console called the Famicom system.

Here is a link that shows how to change/ install the new belt once you get the drive out of your sampler.
