A fellow by the name of Hadden Hoppert is actively working on them.
Last I knew (about 5 days ago), they were coming along, and might be ready to
beta in a couple of weeks. (My guess, not his).  He's on Prodigy, but I don't

Subject: Computer Shopper bogus review
Message-ID: <9309172143.AA43504@ux1.cts.eiu.edu>

I am a new GUS owner, as of September 10, 1993.  I had read the Sound-Site
newsletter for about a year, and followed the ...soundcard news group for
some time.  I choose the GUS since it perfectly matched my needs:

1. MIDI capable
2. compatible with popular games (SBOS works great)
3. actively supported by users
4. relatively inexpensive ( compared to other MIDI capable cards )

I am comfortable making minor software modifications, and have easy access
to FTP sites.  In one short week I have used my GUS enough to know I made
a good choice.

I was quite surprised to see a posting stating that the GUS had received a
low rating in a Computer Shopper article.  I immediately looked up the
article and proceeded to read with unbelief the fact that a group of
listeners had rated the GUS at the bottom of the MIDI pile.

As I read more closely, the truth came out...

The GUS had been rated mostly on it's ability to reproduce sounds read in
through it's 8 bit AD converter, and compared to boards with 16 bit AD
converters.  This was the basis of the Total Harmonic Distortion (THD)
rating, the bandwidth rating, and the general listening tests.

Although it is simply true that an 8 bit input is noticeably worse than a
16 bit input, the article barely mentioned that if the sample is
prerecorded (other than through GUS), in 16 bits, that the GUS, with it's
excellent 16 bit DA output, actually sounds better than all of the other
16 bit boards rated, with the exception of the $599 retail Turtle board.

The factor that motivated me to write this posting is that I feel this
article may mislead many who are looking for the best value in a
multimedia setup.  If one does not wish to record their own sounds, but
rather wants to be able to reproduce existing sounds, the GUS is the clear
winner. ( best signal to noise ratio, second best MIDI sound )

Please read the review, or at least the box on how the testing was done
before forming any negative views of the GUS.

Oh, I do feel better!

Message-ID: <00972AD7.8FF5E681.24971@lsl.co.uk>

What exactly does the GUS CDROM daughter card interface (or indeed
that of any other sound card) do for you? Does it achieve anything
different from plugging the CDROM into a dedicated interface card
other than saving a slot?

I've seen people saying things like "Once I get the CDROM daughter
card, I'll be able to play digital sound direct from CDROM to GUS".
Is this rubbish? (I assumed that by this statement, they meant
WAV data, not just audio).

I know that the GUS has pins for CD audio-in, but these would be
usable whatever the CDROM was plugged in to

GUSDLY03.ZIP contains GUSDELAY.EXE v0.3 and GUSDELAY.TXT

GUSDELAY.EXE is a program written by David MacMahon (me) that enables
your GUS to record data and playback those same data after a delay.
The delay can be so short that you can't notice it or it can be as
long as 256K of GUS memory/sample rate will accommodate.  It
demonstrates (quite well) that simultaneous recording and playback
is both possible and well within the realm of the GUS and the low
level SDK.

Version 0.3 offers the following features:

 * Stereo or mono operation
 * Up to 14 voices can be used (7 pairs for stereo)
 * The volume, delay, and pan position (balance) of each voice
   (pair of voices in stereo) can be independently adjusted.
 * Recording to disk

In short, GUSDELAY turns your GUS into (among other things) an ideal
delay unit for musical instruments that has more functionality that
many delay units costing (almost) as much as your GUS did!!!  (O.K.,
so it doesn't run on a nine volt battery and you can't kick it across
the room... :-)

Enjoy!

Subject: Load and unload SBOS
Message-ID: <9309171330.AA28576@oberon.umd.edu>

Hey all - I recently bought a Thunderboard to coexist with  my GUS and
for the most part it is working fine.  I must say, I am _very_ happy
to be rid of all that SBOS bullsh*t :-).

Loading and unloading SBOS seems to do something to the GUS
(letting some registers 'float' or something is what I've heard) which
allows the Thunderboard to work reliably.  The problem is this,
occassionally (and there does seem to be some pattern to it), I'll get
an 'SBOS Interrupt Time Out'.  Usually, by cycling the power on my
machine I can get it to load/unload correctly.  

So my qauestion is this: couldn't someone write a small utility to put
the GUS into 'floating registers' mode or whatever it is so that a) I
can get rid of SBOS off my drive and b) it will be quicker and more
reliable.  How hard would this be to do?

If someone decides to write this little gem of a utility, could you
add options to activate line in and output, too?  Thanks!

I'm pretty sure that the MIDI box info is in the FAQ - make sure you
get the latest copy though - at one time there was information with
pins backwards on the GUS MIDI connector.

I made by own MIDI box using this information, and it works fine,
if that makes you any more confident!

I tried direct email to "Phil J." <pjohnso2@ua.d.umn.edu> but got

I have modified the redbook cable that came with the Matsumi CD so
that it is now plugged into the redbook-in jack on the GUS.  This
works ok, though mechanically, it is too small to seat properly on the
GUS connector.

I'm more concerned with the performance of the CDROM drive, since I'm
convinced that the drivers that came with the Matsumi drive are not
written very well.  I believe that the Matsumi drive has some buffer
(as documented in the Matsumi manual) that is not being utilized
properly.  I've spent hours playing with the parameters in both mscdex
and the Matsumi device driver trying to optimize the performance, but
I find that although the drive has good access times specs and meets
the 150 Kb throughput in benchmark tests I've run, it frequently
exhibits pauses (drive access light even goes out) that I haven't
experienced with similar drives from other manufacturers.  The best
performance that I've seen has been with the SoundBlaster Pro and
Panasonic (150 Kb) drive.

I was hoping that Gravis might have spent more than just the minimal
effort required to make an interface adapter card, and that the
drivers might have been designed by someone who knew something about
measuring and designing the drivers for best access times, and
throughput and eliminate those pesky dead-times, that I suspect are
caused by poor handling of DMA overrun conditions.

Since Matsumi doesn't have any support numbers to call, and I suspect
they wouldn't spend much effort to address this issue anyway, I was
hoping to interface the drive to a board support by a company that
seems to care what their customers think.  Unfortunately, their sales
department needs to get a manager that understands that the company
doesn't make any money if they take orders and forget to the ship product. 

PS: I wish Gravis would offer the Panasonic 523 (300 KB) CD-ROM as
$200-$250 upgrade to the Ultrasound.  I bought a kit from Reveal at
Best Buy for $325 that offers a card (Soundblaster, SoundSource, Covox
SS hardware compatible) plus the Panasonic 523, two CDROMs (Software
Toolworks Mulimedia Encyclopedia ($75 value) and a special Multimedia
disk put out by Microsoft for Reveal that includes a wonderful
Multimedia tutorial, movies, sound effects, midifiles etc).  The only
gotcha was that Reveal didn't have a CD-ROM device driver that worked,
I had to copy it from a friend who had a Soundblaster Pro, and the
Windows drivers didn't work, so I had to use the ones that come with
windows for the soundblaster card version 2.0 -- Otherwise the package
is an incredible bargain, worth the price even if you threw away the
sound card( Assuming the GUS would drive it).  The sound board is a
curiosity in that it works with native software for the Soundblaster,
as well as native software for Soundsource, or Covox SS.  I only
tested soundblaster and Soundsource quality, which sounded better than
either a real Soundblaster or a real Soundsource in my opinion.  Oh I
almost forgot to mention it even came with a small pair of speakers
($10 value)

I wish I had found this out before I bought the Matsumi CD, oh well at
least maybe I can influence Gravis to save other people from this
mistake by providing a similar bundle with the GUS.  Based on their
experience with SBOS they might even want to strike a deal with Reveal
and offer the Ultimate bundle GUS + Reveal kit for a combined price of
about $450.  I don't see how anyone could top this, as Reveal offers
the 16bit version of this bundle for $550, and there is no wavetable
midi capability.

Message-ID: <2C9A1828@smtpgat2.csir.co.za>

Morning all

I have read with interest - and not a little exitement - news, reviews, and 
general blurb on the GUS - so I decided to go for the big one and so I have 
ordered the MAX with 1meg onboard (at R1405 - not cheap!)  

The vendor demanded a deposit as he thinks I should go for an SB (he is not 
willing to take any responsibility for the GUS card, or its support!)

Having already decided the GUS is the card of my dreams (by mapping my 
perceptions over it, rather than evaluating it (difficult over here where 
no-one is willing to import one with which we can play :( )) I decided to go 
ahead anyway...

Now I read all this good stuff (Ultrasound Daily Digest     Fri, 17 Sep 93  
0:46 MDT     Volume 6: Issue  16  ) about Gravis support (or lack of...) 
along the lines of 'you can't complain about the support - there isn't any!'

am I getting fidgety or not?...

	Was it ever resolved if the GUS has a high enough amount of
thoroughput to actually run a CDROM as a CDROM, instead of just an
audio CD player?

	It's in the FAQ.  Look for "gusfaq" on epas, or mail to the
request server to get a copy.

	Uh oh, it looks like someone didn't read the disclaimer:

	"These lists are not owned or operated by Gravis.  There are
Gravis employees on the lists, but the owner of the lists is not one
of them.  Please don't mail your complaints concerning the Ultrasound
to him."

	Honestly, folks, I have NO idea about your registration.  I
work at a computer graphics company (es.com), and maintain the lists
from here.  If your registration card is here, then the mail system is
more screwed up than anyone has possibly imagined.

The GUS doesn't have a CD-ROM interface, only a CD audio header.  You'll
have to make sure that the Panasonic comes with an interface of its own
or buy the appropriate CD-ROM daughtercard.  I'm not sure if a daughtercard
exists for the Panasonic 562.

Only SOME Opti chipsets have a fault in their DMA controller.  If you haven't
