[sdiy] Moog Voyager Questions

[synth at oldmail.charlielamm.com]

I was at AES show this week (SF, CA, USA) and they had 2 of these at the
Moog booth.  Since everyone was crowded around Digi's site and ignoring
analog synth stuff, I had some time to go check the thing out, without the
usual kid playing Stairway to Heaven when you try to try things out at
GC--ie, it was peaceful.

It sounds to my ears anyway pretty darn Mini-like...very nice indeed.

If I understood the tech at the booth, the Voyager is fully programmable
sort of like the Moog Source or Prophet--you set up the knobs the way you
want and take a snapshot of the settings for later recall.  The tech there
said the circuitry in the Voyager is almost 100% like the original, with
some components changed out to modern equivs for obvious reasons.

Now, this doesn't seem entirely possible to me. I didn't want to argue
with the guy, since he works for Moog and all.  But, how did they get
programmability?  Did they use programmable pots? Vactrols?  The pots did
not feel like rotary encoders BTW. The hardware looked and felt very mini
like which is a big part of the charm of the original for me.  Did they
mod the circuits to (for instance) have VC of filter Q?  Does anyone know?
Are any voyager schemos published anywhere.  It would be an excellent
education to see these, and to compare them to the original, to see what 
the Moog folks did to make this possible.

BTW, I also went by the THAT booth, and the engineers there seemed
thrilled to talk to someone who likes to breadboard VCA type stuff--even
someone with no formal engineering training who sells onesy-twoseys on a
web site (like me).  They gave me lots of samples and were happy as clams
to do it.
