Subject: [GUS] A Couple Problems
Summary: 80ns DRAM's don't work & no sound in Dune
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
I recently purchased my GUS, and I didn't have any problems until this
week. I have been using the newest version of the software available
from archive.epas.utoronto.ca (gus0016-21 and the revised sbos2.04 from
gus0022). Now I've run into 2 unrelated problems:
1) I purchased and installed 6 256Kx4-80ns DRAM chips to fully populate
my card. Following this, I went to windows and changed my ultrasound
drivers to recognize the full 1Meg. Then I started up canyon.mid.
Yikes!!!! There was some horrible static where the drums and a
few of the instruments should have been. So I started up the
ultrasnd/setup program and ran the DRAM test. It came back with
a failure of (351K).
At this point, I opened up the computer and swapped the chips from
Bank2 with those from Bank4, both to check if it wasn't a bad chip
and also to check if the chips hadn't been seated properly. Re-ran
the DRAM test and it failed again with the same value. Tried
another midi file, and it had the same static.
Next, I tried swapping the chips from Bank1 (the originals) with
those from Bank2. Ran the DRAM test and this time it failed sooner
(123K). Tried a midi file and it was nearly all static.
Finally, I homed all the chips back to their original locations, and
then using the patch manager tried each instrument loaded into memory
for canyon.mid. Anything under 256K was fine, but all those above
this had a lot of static.
The original chips on my card are 70ns, and it looks to me like
there's a problem with using the 80ns variety. The owner's manual
clearly states chips of 100ns or faster may be used. Has there been
a change in the specs that I'm not aware of? Or is there something
I need to setup - like a software parameter or a jumper on the card
(couldn't find anything like that listed in the documentation)?
2) Before describing the next problem let me emphasize that it is
isolated to this piece of software. My GUS is working fine with
all other software I have using its original 256K:
A friend loaned me his copy of Dune to try out on my GUS. (Merely
a test - don't get all upset about illegal copies!) It worked
fine on his machine w/ a soundblaster. Therefore, I know that the
copy of the software is good since it was installed (and verified
with another re-install) from the same disk.
I installed it on my PC with SBOS loaded, and it detected the
soundblaster emulator, but then when the game starts, I don't get
any sound at all. If I switch to the map screen and select the
options, it shows that music should be playing, but obviously it's not.
I've tried about a dozen other games that have sound support, but this
is the first one that hasn't worked. Is there something special
I need to set up to get Dune to run with the GUS? I stopped running
with QEMM (Dune intro hangs!), and am now running with a nearly naked
config.sys & autoexec.bat (files=30, buffers=15, device=mouse.sys).
Note: This isn't really that critical, but I've been getting some
ribbing from this guy since I can't get Dune & GUS to work together.
If it helps for either problem, here are my GUS settings:
Addr 220
DMA 7
SB Irq 5
SB DMA 1
Gus Irq 11
E-mail me a reply if you can help me out.
Thanks,
Brent

Are you specifically excluding the 8013e's shared ram area from being
used by emm386 (or qemm or 386max)? Does everything work fine under
DOS? Playmidi, SBOS, etc.? Are you using the latest software (2.02)?
Have you checked to make sure that you don't have old Windows drivers
files in \WINDOWS? (Follow directions from that 4-part Gravis posting
that came along earlier this week.)
If yes, it sounds like you may have a similar problem to mine. My
Windows crashes don't occur right away, but they do occur regularly.
I can run WinJammer and the Patch Manager, play MIDI and WAV files
with Windows 3.1 applets, associate custom sounds with Windows events,
and even play a WAV-based game like JewelMaster while *also* playing
a MIDI file. The AfterDark sounds are great. Really, everything
sounds good and works as I would expect ... for a while. The problem
is that Windows *always* crashes eventually when I do sound-related
things.
I start up AfterDark's Creepy Night screensaver, listen for a while to
the thunder, crickets, and wolf howls, and then it just stops. Sometimes
Windows will pop up a box accusing AD.EXE of a protection violation;
usually everything will die and require a hard reset. It might take
30 seconds or 20 minutes, but it always happens.
I run the Patch Manager, load my 256K Gus with patches, and audition them
as much as I like. I unload all the patches, and on the next load Windows
crashes. Every time.
I play JewelMaster. Often it and usually Windows will crash immediately
after a game finishes; sometimes after 20-30 minutes of play it'll just
die in the midst of play.
I have tried all sorts of configurations of interrupts, I/O addresses,
memory managers, etc. Windows dies with 386MAX, EMM386, or just HIMEM.SYS
all by itself. I have tried booting cleanly with HIMEM.SYS only -- no
DOS=HIGH or EMM386 or any other device drivers, no SBOS, no other TSRs,
just the GUS variables and the ULTRINIT statement. No improvement.
When I unload the GUS drivers, Windows works solidly. If I have the
drivers loaded but don't use them much -- just for the occasional
Windows event -- Windows works. For example, if I mute the sound in
AfterDark, Creepy Night runs forever.
Opti 486/33 (with bad DMA -- I can only use channels 1 or 3)
4M ram
Diamond Speedstar 24X bios v2.03
multi-I/O card -- there's no jumper to disable the game port, and I
*am* using the GUS port. I removed the connecter, and I have had
no problems with the joystick, so I don't think this is an issue.
GUS w/ 256K
Any suggestions? Is my motherboard no good? Gravis, are you working on
this? What can I do to document the problem for you? Is anyone else
experiencing symptoms like these? Is anyone experiencing rock-solid
Windows 3.1 stability even while using the GUS drivers heavily?

Subject: GMOS,_GusMOD...
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
Obviously, explaining all the problems and advantages of a GMOS driver back
in digests V2#60-62 was of feeble use, since it seems few did actually read it
and have therefore been posting again and again the same ideas, wasting
bandwidth.... :-) | )-:
First of all, there's NO NEED FOR *_ANY_* WIRES!!! There's *_NO*_ NEED for
a MIDI-IN to MIDI-OUT or MIDI-I/O to Serial port. The final word on this
I hope.
If you get error messages with the playmidi, make sure you don't have old cfg.
files in that directory.
Sierra and other companies may find it hard to support the GUS. A compromise
available with making a GMOS is that these companies could simply INCLUDE
a .CFG file! Alternately, Gravis could build a simple database which would
have references for most games, with pertinent information regarding the
samples required.
Let me make it quite clear that making a MIDI driver is nothing more than
taking the SBOS engine and substituting the MIDI for the FM. The SB is
as much a card as the GUS and other MIDI cards are, and there is thus
no problem in making such a driver.
What is deplorable is that the SBOS is such a good starting point for a MIDI
driver; having to start from scratch again to implement mainly the digitized
part of the SB is rather - let's just say inefficient (and leave it at that).
Substituting the MIDI driver for the FM driver in SBOS would also, I believe
make the driver simpler, since FM is more complicated (we have there a
4-operator chip). IS there ANY way Gravis/Forte would release to a third
party some SBOS code to develop a MIDI driver, since they do not intend
making one in the immediate future? (Perhaps Josh's GusMOD engine could be
used?)
I had already asked for some docs on the Roland interface (I/O port, Interrupts
and so on) and got no reply...

Well, what do you know.... it just occurred to me that the problem with
SC2 (*buzzing* with 1MB) MIGHT be related to the BUZZING (!) in GUSMod...
AND: Yes! This worked at least now when I tried it...
Seems that there is some pernicious problem involved when clearing the memory.
<Sigh> One more reason to make a dedicated memory cleaner...

In case you don't know the fix: Run G669 - any .669 module should do the trick.

If Advanced Gravis (John Smith) is reading this,
please respond. On your GUS support list, I saw two games
that are actually out but DOESN'T support the GUS. The
games are Lemmings 2 and another one that I forgot the
name.
I'd like to know why they don't support the Gravis
Ultrasound and how many other game companies on your list
won't support it. I can't trust your list anymore. The
first two games to be released doesn't support it.
Please, respond.

2 Questions
======== 1 ========
I tried sampling with uss8 last night. Had my GUS connected via line OUT
to my stereo (per normal), and a separate FM radio connected to the line
IN of the gus. Fine.
When clicking MON, It came thru crystal clear on my stereo, I was amazed!
the GUS was putting through the FM radio to the main speakers with amazing
clarity, I thought for 8 bit this was sensational.
Tried sampling, mono, stereo, 11khz, 22khz all not bad, but I thought I
wouldnt get the same quality unless i went for 44khz st, I did, then played
back and although it was still very clear (ie not much distortion if any)
the sound came back slightly muffled, more like 8 bit.. but NOT up to
the clarity of the MONitored sound, which was identical to the quality
of the stereos own internal radio receiver.
QUESTION: DOES THIS MEAN that the GUS, when you MONitor on uss8, simply
thru-put's the line in directly to the line out, without passing through
any DAC's?? It would seem so judging by the clarity of the MONitored sound
compared to the sampled sound at 8 bits 44Khz stereo.
Can someone confirm or deny this either way?
If so, it would also be interested to see if, with a 16 bit dboard, the
sampled sound that comes back is identical to the MON sound.
Another thing, ramdrive is the ONLY way to go when using uss8

Why isnt this program on epas OR wuarchive?? This is the answer to my
prayers, because although the SCII bug of distortion with 1 meg of
GUS memory can be cured by p669gu0.exe, that program wont work when
EMS is installed, and I need EMS to play star control 2 properly!
Can someone in the U.S. PLEASE upload this program (and others on the
Gravis BBS not on epas or wuarchive) to either epas or wuarchive so
us non Americans can have access without having to spend $$$$ on overseas
phonecalls? PLEASE!!!
Or a suggestion for any other program that WORKS with ems and clears
GUS memory, would be nice.
Thankyou

Subject: MIDI box and recording "variance"
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
Okay, thanks for the help with the MIDI-box (specifically, info about my
Philips optoisolater.)
About the 1-bit variance with recording...then why didn't gravis/forte use
a 9-bit or 10-bit A/D converter, and use ONLY the 8 MSBits? Wouldn't that
fix the problem (grin) ?
As for the 16-bit recording card? I understand that variance would be a much
smaller problem (although still existent), but likewise, would the "variance"
problem be eliminated by using an 18-bit A/D converter, and using only the
top 16-bits?
Also, what kind of A/D converter does the 16-bit recording board have? Does
it have a D/A of its own? And, for the A-law and u-law sound compression,
is this hooked up to the GF1 chip? I mean, can you play 32-simultaneous
samples with A/U-law compression? Or can you only have 1 (or 2 for stereo)
concurrently?

Subject: Noise in recording (again)
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
OK, I'll try to make this short.
I just tried recording some silences files thru line in (I actually grounded
the wires together. Yes cut off the jack physically.). Both in stereo and
mono. As yesterday's digest suggest, they are mainly 1 bit variances. So
I guess they are ok. But howcome they are at 85 or 84 instead of 7F? I
know someone noticed this before and hence the sndfix program. (Much
credit to the programmer. Good work noticing this.)
Also, despite that the file only contains one bit variances, when the
file is played back, there is substantial background noise! I don't understand.
I know that a lot of the files from the commercial programs have a lot less
noise when played back. Why this phenomenon?
John Smith? Any answers?

To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
Someone stated, that it would be more important to have NT-drivers for
the GUS (based on 70000 beta-copies) than for OS/2.
I don't think, that 70000 beta-copies are a good base for immediate
support (especially when you regard the over 2 millions of installed
OS/2 copies).
Another point is, that NT-drivers might (if the GUS is successful on
the market) be included in WIN-NT by M$ itself. But there is hardly
any sound driver available for native OS/2 for any card. So these 2
million copies would be a good base for support, as for these users
the GUS would then be the ONE and ONLY (and plus VERY GOOD) soundcard
supported by their system.
Just my $ 0.02. Flames directly to my address, constructive critizism
to the list, please.

Subject: Patch Location in Stereo Space
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
Has anyone else noticed that when using Patch Manager, and occasionally when
playing a Midi file that consists of one instrument (ie, piano>, the
odd note will sound from one speaker side or the other, rather than both,
as it usually does? I am not referring to any of the patches, such as
String Ensemble, that shift location as pitch goes up or down, but rather
patches that <usually> stay put all along their range...
At first I thought this was a bug in Patch Manager, which is where I first t
noticed it, but now I'm inclined to think it's a bug in the Windows driver,
for I've had it happen in Media Player and Winjammer, as well. Of course,
this could also be a feature that allows you to ping-pong sounds and get
those crazy stereo fx, but I've heard nothing that supports this theory
anywhere.
To duplicate this effect, try hammering on one note with your mouse in
Patch Manager, and with any luck you'll hear, sooner or later, the note
coming from the left or right rather than the middle. Unless, of course,
I'm just hallucinating from too many nights spent diddling around with my
GUS.

Yea, I've had alot of trouble running Zone 66. It seems that it won't work
with my memory manager. Nor, of course, will it work with OS/2. For some
odd reason, people feel compelled to write code that tries to do things
that the OS does (or should do). I sorta refuse to have "boot disks" for
games (like Zone 66 and Ultima 7) that won't "play by the rules." Since I
do other things with my machine than play games, I don't want to have to
reboot everytime I want to change "tasks"...
Am I the only one bothered by this?

Jay,
I have read the promo that was sent out regarding ID's new release DOOM.
I was wondering on behalf of all Gravis UltraSound (GUS) Owners if DOOM
will be supporting it in native mode? Or if there would be an upgrade
patch available to us GUS owners, etc. As you have probably heard the specs on
the GUS I won't reiterate the reasons to support it. Although I will say
that as a GUS owner I would much rather support games that support my card
in native mode(as would many other GUS owners I am sure). I would also think
that a revolutionary game like DOOM would use the awesome technology that
the GUS has to offer. I appreciate any response on the subject of GUS
support, and will relay this message and any reply I recieve to the
UltraSound Daily Digest.
Thank-you for your time,

Talk about great hey. Chalk one more for the GUS! I think that if great
companies like ID support the gus then in a short time all the major
software companies (who cares 'bout Sierra though) will support it.
seeya later, and happy GUS'ing!

Subject: Surround Sound?
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
Here's something else to think about...
In addition to all the talk about 3d sound and QSound, I was wondering why there
was no disscussion of Dolby Pro Logic Surround Sound. I know that Dolby
Surround requires two digital sound wires in order to decode for the four
speakers (five in Pro Logic). BUT, There is a way to produce True Surround
sound through the use of one stereo output. If you feed the output of an
ULTRASOUND into a Dolby decoder it will decode all sound onto the front
speakers. Although, if you take the output of a portable cd player and plug it
into a decoder (or reciever that has it), it will come out in full 5 speaker pro
logic form.
Does anyone know more about the subject? I think it would be very possible for
Gravis to write music or maybe it requires additional hardware, that will
produce the 4-5 channel sound.
On another note, Nintendo has achieved this with their Super Nintendo 16 bit
system. Some of the newer carts will feature Dolby Surround Sound!

UltraSound 03/30/93
-------------------
1) A few days ago I posted a long tech note from Gravis and Forte.
The last line of that message said, "5) Being overly critical
of a $150 sound card....". This was suppose to make you laugh!
I've heard from a few people who didn't find this very funny.
Yes, we do make attempts at a little humor now and then. ;-)
2) There has been a discussion over the last few weeks about recording
silence with the GUS card. People have been complaining of
popping or static periodically. Here are the results of some
testing I've done.
To test the recording of silence I shorted out line in and mic in
using two phono plugs. NOTE: You can short our your GUS inputs but
NOT the outputs, line out, or amp. line out. I used PLAYFILE and
USS8 to handle the recording and both returned the same results.
The 'static' you are hearing is due to a 1 bit variance in the
recording. Silence should be recorded as DC offset 0 (7Fh) on
the UltraSound. A +-1 bit variance is actually very good for
an AD converter. Even a +-2 bit variance is ok.
When recording silence your ear is very sensitive to any shift
in the noise pattern. Which is why this your ear can pick up
this bit difference when silence is recorded.
In the test files I did, over 95% of it had a DC offset of 0.
There were only small sections of the file that had small periods
of this 'static' (+-1bit). Remember, this is only noticeable when
recording silence. If you are recording noise you wouldn't be
able to hear this small of a difference.
A couple things to keep in mind though:
EMM386 or any memory manager will affect your recording
performance.
A disk cache will help your performance.
Make sure your hard disk is not overly fragmented.
Mic in will cause more noise than Line in due to the fact that
it is amplified.
Even with a 16bit recording card you will still get this variance.
However, it should be less noticeable due to the larger
sampling window.
For those of you who want to test this, try creating a file full
of 7Fh. Make sure you use a hex editor and not a text editor.
You may then use PLAYFILE to play it back. Now go in there and
change a few bits to either 7Eh or 80h and hear the difference
it can make.
3) Boy did I screw up. It seems in our "Authorized Gravis Nodes"
list I put my home phone number in there as the Gravis BBS phone
number. Guess that explains why I was getting calls at 3am <grin>.

Subject: Windows Sources review
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
Concerning the ridiculous notion that a PAS-16 and SB Pro are better
than the GUS....
1) Most Windows magazines like supporting readily available (and therefore
supported) hardware and software. This is commonplace with Windows because
most people want 'instant compatibility' which the GUS does not offer.
2) Most Windows magazines (Such as BYTE, et al) tend to worship whatever
bit of gospel-code that Micro$oft writes. For instance, the jerk-off
(NO, I WON'T APOLIGIZE FOR THAT) that wrote the 'Year's Best' review
picked a @!#$%$# card game written by Lord Gates and his Merry Minions,
over such wonderful games as Dune II. Since these losers know little
about software (they must, since they use Windows) they probably know
less about hardware.
Just let them listen to some midi and then do a cost comparision. For overall
audio performance, the GUS is better engineered (Rah rah Forte ;-)) and costs
less than the crap that Creative labs egests. Hmmm....Why does the SB Pro
hum when the mouse moves? Must be because it's a well designed card.

1st I guess you would power the mike. But then you get a signal that is
also powered. I do NOT think this is compatible with a line-in at this
point.
There should be a simple circtuit one could build to take the output from
this powered MIKE and transform it ot either MiKE (input) or LINE-IN.
PRIZE!!!
He or she who comes up with the first circuit will get a FREE
Apple powered MIKE in the mail from me.... ( hey its all I have...)
Any takers?
Thanks,
MikeE
