Hi All,
Many thanks for the mention Josh, still no news from Per I'm afraid, 
maybe he hasn't accessed for a while. Next up should hopefully be The 
Arp sequencer manual, I've just been sent some Prophet 2000 stuff 
which explains why a 12-bit sampler should sound so good, it had 
analogue VCF/VCA/EG chips following each DAC! I'm now on the low-level 
lookout for a P2000 to strip for bits, at least to have a look, they 
only fetch a couple of hundred pounds, eight VCF's. eight VCA's and 
sixteen EG's is worth more than that to me. They are almost certainly 
SSM devices (might be more than one per channel though because of the 
big tie-up between SSM and SCI. Also soon, hope I get a chance to 
sneak into work next week and do some serious scanning in the 
evenings, I've got the Moog 15/35/55 manuals, you can see for yourself 
what kind of madman my friend Paul is. BTW he's got most of his 
replica running now, some tething troubles, but not too serious....
Would anyone be interested in a Vocoder design that is still 
buildable, cos I've got the Elektor one. You get to build a lot of 
boards for it, like ten for the channels, an output board, a PSU, and 
two backplanes, but it works, it sounds pretty good, or at least mine 
does when it's working, and if you build it properly *mine was my 
first big thing so it's a bit cranky*, it's pretty reliable.  I at ll do 
it if there's interest. There should also be a re-laid version of the 
Elektor Midi-CV converter. Really basic, note and gate, but my version 
is easier to do with home etch equipment, and also incorporates an 
option for a +/-12 to +/-15V PSU as well as the single-sided 12V it 
originally ran on. Running bipolar means you can use something other 
than the TL061 they used on the output, like an '071 or an '081 or 
something else with some drive,...
     Feedback wanted on-list or to me over what next for Red Cross 
     parcel to Josh <g>
