The OPL3 can provide 4 operator FM synthesis, instead of the 2 operator
provided by the YMF262.  And it is stereo, not mono.  
Both Creative Labs and Media vision have switched to it on their high=end cards.
(e.g. PAS-16, new SB Pro's).

_IF_ Gravis is using a Sierra chipset, why haven't they announced it?  And 
the name "Gravis" is conspicuously absent from the list above of companies with
cards in the works using the Sierra chipset.  And since the price on the 
ST8002 chipset has been reported at around $70 in lots of 10,000  is it very
likely that the Gravis, with a street price of $125 (or $99 in the Electronic
Arts deal) uses it, given all the other chips that have to be on the card?

I don't think so.
  These other cards that are announced as using the Sierra chipsets will cost
more than the Gravis and will presumably have better sound.
Finally, as I noted in my earlier post on the Sierra announcement, they have 3
chipsets coming out.  The  ST8002 is the top of the line, and the most
expensive.  The low-end ST8001 has no ROM sample, is substantially cheaper,
 and MAY be the set that Gravis is using, although this is purely speculative
and not based on any useful information I have ever seen from Gravis.  I hope
it turns out to be a great card, but I don't think it is using the better chip
sets.

I recently purchased the PAS-16 and got it working, but still have a few problems:
1) I can't seem to get EMM386.sys (Windows 3.0) to work properly. Says DMA mode not
supported.

2) (more important) I have SBDOS 1.0. I tried it out but the code never seems to get
any ACK interrupts from the SB part of the card. I am using the default card jumpers
which should match the code. Did I miss something here?

The PAS-16 does support Windows, I'm not sure about OS/2 2.0.  Pricing
from mail-order companies is around US$215-$240.

Reply-To: gfr@dulcimer.mitre.org (Glenn Roberts)

It appears there is an incompatibility between the SB Pro 2 and certain
(apparently very few) motherboards (at least mine!).

symptom:  Only FM synthesis is affected (MIDI and CD ROM work fine).
Symptom is occasional note errors (notes last too long or are in the
wrong voice; sometimes voice changes dramatically while playing -
sometimes to a loud or hissing noise; sometimes notes are left "on"
after music stops).  problem can be made to occur with test-sbp program
but seems to be more likely to show up when running something more
complicated (e.g. using voyetra sequencer).  problem is very sporadic.
When CPU speed is reduced (via "turbo" button) to 6Mhz the symptoms
diminish but do not go away.  Computer bus is set to slowest speed.

what was tried: everything I could think of.  all settings for port,
IRQ and DMA settings; removing all but essential cards from system;
booting from generic DOS diskette and running test-sbp off the SBpro
dist'n. disk; swapping disk controller and VGA cards; putting SBpro in
different card slot, etc.  I repeated the problem with 4 different
SBPro cards (two of which were demonstrated to work fine in other
computers).  All were version 2 (OPL3 chip) boards.

what Creative Labs said:  they admitted they've found a limited number
of motherboard incompatibilities and suspect this is one.  ALL THE CASES
THEY KNOW OF HAVE BEEN WITH THE OPL3 CHIP (i.e. the new Sbpro 2 that
comes with the "Basic" kit).  They suspect if I went to the older SBPro
my problem would go away. They did not offer to swap boards with me nor
will EggHead (where I bought it) so I may just get my money back.
Creative Labs basically said "don't call us, we'll call you" and
admitted it may be some time before problem is identified and
corrected.

The machine that has the problem is a Gateway 2000 386/33 that's about
2 years old.  it has the Micronics "baby" motherboard and Phoenix ROM
BIOS.  The machine is working fine in all other respects.  It also ran
fine with my previous SoundBlaster (non pro version).

Has anyone else seen this?

This is information from a recent issue of PC Week Magazine Vol. 9 No.27
(copied without perssion - hope no one will mind too much)

For those interested here are some specs on various synthesizer sound chipsets.

Firm				Chip Set	Recording	#of	Instrument
----				--------	Resolution	Voices	Sample Lib
						----------	size
								------	----------
E-mu Systems			SoundEngine	16-bit		32	4M bytes

Sierra Semiconductor		ST8002		16-bit		32	1M byte
Yamaha Corp. of America		YMF262		16-bit		22	none


The ST8002 and the SoundEngine use wavetable lookup or digital sampling. Real
instrument sounds are packed in ROM to achieve high-quality synthesis. The YMF262
provide FM synthesis through sine waves that emulate real instruments( this is
not preferable for complex sounds, ie. piano, or string instruments).

THe article also mentions companies that will have sound boards this fall,

Cardinal Technologies, Zoltix, and Digital SYstems.

There is one other chip that is mentioned, but I have no info on it that is the
Yamaha OPL3 chip.

BTW - if the GravisUltra sound is using the Sierra chipset the delay in shipment is the result of Sierra ony being able to ship the chips in august.

The SB-Pro has a built-in mixer that will allow you to plug the output
of your MT-32 into one of the inputs in the SB-Pro card, mix the
sounds, and put them out together.  BUT, the mixer needs a DOS TSR
that takes up something like 70k!  I almost upgraded my SB 1.5 card
to an SB-Pro, but I didn't want to fool with stupid DOS TSR's, especially
since I'm running OS/2 now.  :-)  Soooo, what I did was the following:

--bought a Roland LAPC-1 ($369)
--bought a used stereo mixer ($99)
--bought a used stereo amplifier ($119)
--bought some nice AAL shelf speakers ($120)

In other words, I sold the farm and got a great system!  The benefits
include being able to completely control the sound, mixing, equalizing,
etc. of the two cards externally without having to mess with software
or stupid TSR's.

I think Radio Shack has a stereo mixer for about $35.

Games that use both cards simultaneously (MM3, WC2, SQ4) sound great.
I can adjust the levels of the two boards' outputs at will with the
stereo mixer--it's great.

My impression is that the older FM chip used on the adlib and soundblaster is
 just 2 operator, and that the new chip (20 voice stereo) can do 4 operators
and has a better signal to noise ratio (16 bit DAC?) This chip is used on the
PAS-16, and the newest Soundblaster (not the Pro).  The old chip is the Yamaha
3812; the new one is the YMF265 or "OPL-3".  Please note that just because a
card does stereo does NOT mean it has the new chip.  The SB Pro just used 2 of
the old chips.  Be sure to get the new chip (doesn't seem to cost any more and
supposed to be quite a bit better). 

If you already have a keyboard,  I would think the cheapest way to experiment
would be to get a PAS-16 or an old Yamaha synth module (TX series).  If you 
do not have a keyboard, then why not get a
newer Yamaha, like the SY-22?  It gives you some sample playback in addition
to the FM, and even new it doesn't cost that much more around here than used
DX-7. And has many more midi and keyboard features.  
But I don't think you get any more operators than the soundcards....

SB Pro or the PAS-16. I want to use it for sequencing my synth rig,
as well as programming applications under win 3.1. I understand that
the PAS-16 costs a bit more. Does it come with a MIDI interface like the
SB pro? Is the higher sound quality of the PAS-16 worth it? How well do
each work under win 3.1? And.. if the PAS does not come with a MIDI
interface, is it still worth it? I mean, for the total price of
card+interface? Inquiring minds want to know!

Date: 24 Jul 92 08:53:34 GMT
Organization: Netcom - Online Communication Services  (408 241-9760 guest)

I got a beta version of the Ultrasound board a couple days ago.
They say the board will ship in early August.  Here is my impressions
of what I think of it.

First off when you see the card you notice that it has sockets for
memory expansion.  It came with 256k on board expandable to 1Mb.  
Exactly like and typical 1MB VGA card.  

This card is not an FM card like all the others on the market.  Gravis
is using wavetable synthesis for all the sound generation.  It resembles
how MOD files are written and played.  Sound Patches (8-bit or 16-bit upto
44.1k) are loaded into the memory on the card and then the software controls
when to play back the specific instruments.  You can manipulate the patches
in many ways.  Sure enough it's got 32 voices with each being able to
play any of the patches loaded in its on-board memory.  
  Each voice can:
    Pan left or right with 15 positions.
    Frequency shifting to play different notes.
    Amplitude modulation for note enveloping
    Volume control/special effects (low frequency amplitude modulation)
    
You can record and playback samples simultaneously easily.

This card is Adlib and Soundblaster compatible with a driver from Gravis.
I have not obtained this yet.

How does it sound?
  Comparing it to all the cards I have currently, It sounds better than 
the Adlib Gold (w/surround).  It's not even in the same class as the
older Soundblaster/Adlib cards.  The samples included in the demonstrations
were 16 bit patches which really showed off the board.  It's on the top
of my list for overall quality.  The benefit of storing the Sampled patches
in the Audio RAM is awesome.  Just a little bit of the conventional RAM
to play the music back leaves a lot of breathing room for some of the 
upcoming games.  I plan on supporting it.

  Ultrasound board with a newer, enhanced version of the Chuck Yeager's

I thought the recent games from Sierra support 2 cards at once: one for music
and the other for a DAC.  For example Robin Hood: Conquests of the Longbow
asks you to choose 2 cards if you want during the setup.  Then it plays the
music on the LAPC and (in my case) makes the arrow hitting sounds on my Disney
Sound Source.  This is from memory and I can't confirm where I am this summer.
 Perhaps someone else can.

Well, you do... come on, put your hand up! :-)

OK, I'll admit I have done two. The second one I did only earlier today.
Look for fugue_in_g.mod.. I did have it posted to alt.binaries.sounds.misc, and
I might have even uploaded it to info.brad.ac.uk.... ? fugueg.mod on ftp sites.
(Bach's Fugue in G minor)

I've just finished Schubert's Litany, and I've only sent it to one local BBS
yet... coming to absm soon, promise! :-)

Regards,
Hamish
