Found this older post in the archives, but was wondering if the info that
**used to be** at this URL is somewhere else now??

i guess that could be *one* potential problem with getting a Zefiro Acoustic
ZA2 card to coexist nicely in a PC; i'm glad RT solved his problem so easily
:)
sorry for this long post but i need to try to explain this to Za2 users so
as not to give anyone the wrong impression about how EZ or difficult it may
be getting a Za2 to behave in your PC
you (the reader of this note) may or may not have difficulties getting a Za2
to work well in your own PC, and although the difficulties may be solveable
by simply following RT's advice above, you may instead find that alot of
work on your part may be needed to figure out the problems (like Tim), or
you may exhaust your options and find the card just will not work correctly
for you (like me)
after mucho time & research on my part & tinkering etc i gave up on getting
it to work right in my PC; i believe in the end it just didn't like my video
card or *something that i could NOT figure out*
after a bunch of config debugging/work i was able to get around all the
buffer overrun errors (thanks to greg hanssen & the Za2 discussion group),
but nothing solved the most dreaded channel swapping problems that i only
discovered by chance (& a discerning ear)
there used to be a ZA2 discussion group solely devoted to debugging/figuring
out how to get it to work right - my point being, it is not as simple as
what RT posted above...there are many complex things you *may* have to do to
get it to work solidly
i gave up & replaced my Za2 with an EGOSYSWAVETERMINAL2496...works smooth as
silk....i found that there were just too many PC issues with using an ISA
based card like the Za2, in my particular PC...that is not to say that there
is anything bad about the Za2 card...it is just that it CAN be one hell of a
monster-sized problem to get it to work right in some PCs
also for tim - and RT - and any Za2 users - i recommend strongly that you do
some serious checking to be *sure* that the Za2 is NOT channel
swapping....after transferring several DATs to my hard drive with *no
errors* & thinking the card was working well (after i fixed the buffer
overrun problems with a bunch of config steps like tim discussed), i
discovered to my horror that something wierd was up with my transfers :-(
while listening to a show that had very distinctive stereo channel
seperation, i noticed that at certain times the musician on the left side
was coming out the right channel and vice-a-versa...at first i thought i was
going crazy...then i thought there must be something wrong with my
tape...then i went back & listened to the tape & discovered that the
switchover was NOT on the tape....then i researched horror stories on the
Za2 forum and learned about "channel swapping"
then i did a simple test.....and about 50% of the time i had "channel
swapping"...try this:
- feed your Za2 input that ONLY has one channel, either right or left
- let it soak that up for awhile
- examine the waveform in an editor like cooledit2k & MAKE SURE that the
sound is ONLY on the proper channel
- if you see it "switch" from side to side, you have a channel swapping
problem (& one hell of a problem to debug)
- to be as safe as possible try the test multiple times under different
conditions..if everything is ok breath a sigh of relief
if you see channel swapping, try reading through all of the posts at
http://www.hollister.nu/david/za2 and you may learn enough from the
archives to pinpoint & solve your problems..or search the net, there may be
other forums out there for Za2 users that can help

If you live near any major city, it's worthwhile to check out the
AES site, http://www.aes.org/sections, and see if there's a chapter
near you. They have a lot of interesting meetings for us audio
geeks - last month's LA chapter meeting was a demo of 10.2 audio.

I recorded The Chris Duarte Group from the board there about 4 years ago
with no problem. In fact, the soundguy set up an aud/sbd matrix for me,
using his own mic! He was cool as could be. His only question was about the
group being OK with taping...after that was settled, I had it made.
Again...that was a while ago...things can change. I'd just call the club and
ask the manager if that's still the case.
I have no clue about The Yardbirds policy though...

Hi,
I am a blues lover who has been been taping blues for
many years. Living in Chicago has made that easier,
and is a big bonus as a blues fan. Many of you have a
show i recorded after an Allman Bro's show back in 96.
Magic Slim w/Warren Haynes at B.L.U.E.S. I am hoping
(requesting) that many of you take the opportunity to
record many of the great blues festivals around the
world. Most of you know of your local blues fests, but
there are good resources to find other ones.
www.bluesfests.com
www.bluesfestivalguide.com/festivals.html
If you have taped or will be taping any blues shows,
please get in touch with me as i would like to get as
much live blues as i can
If you wish to trade any blues, send me your link or
list
Thanks,
DJ
