[sdiy] Analogue Shift Registers?

[Electronic Battle]

Hello All

 I'm planning on building one in Eurorack format - I've seen a couple of 
circuits e.g. CGS catgirl or the original Serge one
http://www.cgs.synth.net/modules/cgs34_asr.html or c/o 
http://www.ear-group.net/model_23.html )

 1) Does anyone have any URLs for more examples the could point me towards 
please?  I'm interested in perhaps employing something like the Analog 
Devices' smp04 or even the smp08:

 http://www.analog.com/en/other/sampletrack-and-hold-amplifiers/smp08/products/product.html 2)Has anyone used the Doepfer A-152 in the "shift register" mode?(http://www.doepfer.de/a152.htm )(not DIY I realise - sorry). I don'tunderstand this module yet so I cant tell if it'll do the same thing as(e.g.) plan B's model 23 ASR or the aforementioned ones. 3) and finally (and most frustratingly) I downloaded an MP3 from a URLwhich demonstrates nice use of an ASR kit - I think - and now I can't findthe original URL.  Please could someone listen to http://www.nitrogen.myzen.co.uk/Misc/binaryzonish.mp3 and let me know if they recognise it from somewhere? I'd like to find theoriginal website. I'll delete the MP3 in a couple of days. I've looked atBlacat and MOTM and CGS and PAIA but no luck yet. Thanks EB
