[sdiy] step sequencers & verbos buchla modules

[pj]

hi all,

i'm looking at options sequencing my handful of modules (oakley and 
cgs),  and so far it's come down to either:

a) soft sequencer [ numerology on mac osx <http://www.five12.com> ] 
and a midi2cv converter

or

b) a diy step sequencer. i've been looking at the superseq, serge tkb 
schematics, moog 960 and also the 'supermoe' pages. unfortunately my 
design skill are minimal so i'm limited to working from pcb layout's 
etc.

i'd be interested in getting some opinions/recommendations on 
hardware step sequencers as i'm a little lost! obviously the soft 
sequencer/mid2cv is going to be the cheaper opition, but what will i 
be missing out on if i take that path?

I'm also wondering if anyone has a copy of mark verbos's old buchla 
cloning pages, I'd grabbed about half of the pdfs a year or so ago, 
but the site now seems to have vanished.

cheers

Paul
