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.

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? -- Marc Rouleau ------------------------------ Date: Wed, 31 Mar 93 16:46:34 EDT From: "The Punisher" Message-Id: <0096A56C80E2DA00.0001703E@acad.wit.edu> Subject: GMOS To: Ultrasound Daily Digest Just a quick question. What exactly is GMOS? Is is an operating program like SBOS? -Chris Colotti ------------------------------ Date: Wed, 31 Mar 93 16:03:59 GMT From: laurent@ismennt.is (Laurent Somers) Message-Id: <9303311603.AA19220@akureyri.ismennt.is> Subject: GMOS,_GusMOD... To: Ultrasound Daily Digest 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...

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 ======== 2 ========= This is from digest volume #25: >Logging into Gravis' BBS last night (01/26 - Tues), I discovered a >number of new uploads.

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.

Liao Message-Id: <199304010106.AA11619@aerospace.aero.org> Subject: MIDI box and recording "variance" To: Ultrasound Daily Digest 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? ------------------------------ Date: Wed, 31 Mar 93 23:49:57 -0500 From: mtl1@crux2.cit.cornell.edu Message-Id: <9304010449.AA17029@crux3.cit.cornell.edu> Subject: Noise in recording (again) To: Ultrasound Daily Digest 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?

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.

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 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. ------------------------------ Date: Wed, 31 Mar 93 16:24:52 -0500 From: "It's your hand, Buckaroo" Message-Id: <9303312124.AA03378@magick.tay2.dec.com> Subject: Pet Peeve (Was Re: Zone 66 - Parity Errors) To: Ultrasound Daily Digest > Has anyone else had trouble running Zone 66? 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?

Unfortunately, the columnist mentioned every soundcard but the GUS! Also, apparently PC Magazine will be doing a review of all of the soundcards in their next issue.

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.

To: Ultrasound Daily Digest 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! Matt ------------------------------ Date: Tue, 30 Mar 93 13:11:19 From: john.smith@gravis.com Message-Id: <9303301311.A8918wk@gravis.com> Subject: ULTRASOUND 03/30/93 1/2 To: Ultrasound Daily Digest 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 .

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. ****************************************************************************** * * * If Windows is such a great, intuitive interface, why does Norton Desktop * ****************************************************************************** ****************************************************************************** * * * Jeff Salzmann, 5th year Microelectronic Engineering * * Hater of Windows and all other heavily supported garbage * * User of OS/2 and somebody who would have bought a Mac Quadra 950 * * If he had money... * * * * JKS4675@RITVAX.ISC.RIT.EDU * * * ****************************************************************************** ------------------------------ Date: (null) From: (null) To: Ultrasound Daily Digest 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?
