This is a very signicant issue
and i encourage all the members to weigh in on it because the group
will be most useful if consesus on a 'topic' (or topicS) is achieved.
Such consesus is a real courtesy to the moderators. It really makes
their job easier because we police ourselves and it helps reduce OT
squabbles. Good fences make good neighbors.
This issue is also gonna be a slippery trout to get in the creel
because the category of gadget (CVS) around which this group is
centered is a "liminal entity" (i got that from the "Analog Days"
book.... what a deliciously weird term! -liminal entity-).
To save you all a link to dictionary.com, a liminal entity is a
something that lives on a threshold between two realms....
like a flying fish, an amphibious car, and that frequency range from
0.5 to 20 hz where a pulse train turns from clicks to a tone.
a CVS is simply a programmable function geverator. Aaron Lanterman has
pointed out that NI makes commercial 'data acquistion' gadgets with a
couple of outputs for which there are numerous PC& MAC support
packages and development environments. Eric Brombaugh posits that if
we're going to be wiggling voltages around with code , why not wiggle
them real fast and make audio with 'em too? DIY digital audio!
it's simply a matter of scale....
[This is a bit funny, because when i teach clases in electronic music,
i stand on my poor pupils desks and exhort them to throw away their
preconceptions about what a module does. A VCF is a (damped)
oscillator, and LFO is just a cap-value from a VCO ...etc.
i pout and tantrum until the poor browbeaten sprouts color outside the
lines...]
but in this case
my vote is that we draw some lines and try to stay in 'em.
Good fences make good neighbors.
i'll proffer my postion this way:
The attributes of the topic that i (and i speak only for MYSELF)
intend to expose and exploit in this group are:
-DIY
or DIY-ish , kits, mods but not limited exclusively to one device
-programmable
at some point in its production
-CV o r i e n t e d
i'm not above driving an LFO into low audio but... i'm not sure that
i'm prepared to discuss tweaking the tuning and scaling to 1/40th of a
cent
That's where my chalk lines are.... how 'bout y'all???
If the moderators choose they could segregate this group structure
into sub-topics (fast-wiggling/slow wiggling) or just hose down the
corral and turn the varmints loose!
But let's cut 'em a break folks....
post a comment or two on what YOUR particular flavor of the fetish is
so they can get a few pins in this map.
and on that note....
Thank you Eric for weighing in right off the bat and getting this
issue on the table from the get-go
carpe themam!
