 Yes, I have set up the GUS to use DMA channel 7.  It works fine
 for me.  Read my review of the GUS in issue 31 of the digest
 with subject "The Gratuitous GUS Review (I GOT MINE!)" sent out
 on 26 November for a detailed description of my hardware and

I downloaded GTS yesterday and tried loading one of the song files that 
come with it.  It was very crackly and of pretty low quality.  Besides,
the "GodFather" didn't quite sound like the "GodFather" in terms of speed
and relative pitch.  Does anyone have a solution to this?  I tried
sbos -o1 through -o3 but it doesn't help any.

   The reason you need 6 44256 DRAMs to finish your GUS out to 1 meg is that
the card already has 256k on it.  Now, the reason it takes 2 44256 DRAMs per
256k is that 44256 DRAMs are 4 bits wide, and thus you need 2 of them to make
256k of 8-bit memory.  It is also for similar reasons there are now 3 chip 1meg
SIMMs.  They just use 2 4meg by 1bit chips and a 1meg by 1 bit for parity.  As
long as there is 1meg x 8bits the combination is only limited by the
addressing scheme and extra hardware involved.

   Now, my question to the net is why some people bother to post an "answer" to
someone's question and then come right out and tell you they really don't
know?  Seems a bit wasteful and extremely pointless.

Well, for those of us waiting for the Gravis Ultrasound to show up in retail
stores, the waiting has apparently ended....

I spotted an UltraSound at the Electronics Boutique at Willowbrook Mall (NJ)
going for $159.  Not a bad price, I probably would have bought it if I'd had
the cash on hand.  So, it shouldn't be too long before it becomes available
in the other retail stores and mail order places, if it isn't already...

Just thought you might be interested.

I went out and purchased Mantis today, without waiting for a response.
To my suprise, it actually works quite well.

There seems to be no noticable system 'slow down' from SBOS.
Some of the sound effects (.voc's) don't play properly though. The effects
will sometimes work, and sometime not.  I tried various modes with no real
stable results.

Apperantly MicroProse is bringing another version out on CD-ROM with 80Megs of
data.  Does anyone know if they plan on directly supporting the GUS?  With a
game this hot, one would certainly hope so.

Subject: More GUS - SBOS Games...
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

I've recognised that also other people is getting sound out of their GUS 
with the well known SBOS. (I'm mayB one of the few which can get asleep at 
night, and still own a Gus. It seems like this is the case with all 
complaining around.... Me, myself and I think I've got the best card anyone 
can get.)  It's too many people out there writing PAS16 vs SB16 vs GUS.  
Can't U folk see that it is a new standard coming up???  (I can....!)
No, this wasn't what I really should.  I'm giving U my favourite list of 
games.
It's short, but I think these games are the most popular, or will be:


Monkey Island II: 
		 -Music and soundeffects are as good as they can be.  It 
		  sounds different from my old SBPro (I've never expected 
		  something else) but the soundquality is really great.

Fate of Atlantis:
		 -Same as Monkey2.

Alone in the dark:
		 -The best result so far with SBOS.... It just can't be far 
		  away from the real thing.....(without Sbos...).

Incademo(-when can we get the game?):
		 -Really great quality of sounds (also with dig.speech).  I 
		  hope the rest of it will come ASAP (and as good as the
		  demo). I couldn't see any slowdown(maybe 'cause the 50MHz).

Kyrandia :
		 -First of all. The music in this game will be classics.  
		  It's the best music I've ever heard in any game.
		  With SBOS the symptoms rules as with LucasArts games.
		  
King's Quest VI :
		 -I got the digisounds playing with "-o3" ,and everything is 
		  working, but sometimes the volume adjusts a little weird.
		  I have not figured out why this is happening, but I'm 
		  through the game so I don't care :-)

About Falcon 3.0:
		 -I got the sound working in the intro when I loaded SBOS 
		  into highmem. The birds where there, the jet-engine, the 
		  explosion also, but it was a sound of "electrical noise" 
		  there too, which was not so good for my earphones I think.
		  Therefor I don't load SBOS high before running Falcon 
		  anymore.

Dynamix-Games like:
		 -WillyBeamish, Hearts of China and Red Baron works very 
		  close up to LucasArts, like I said, a little bit different 
		  from my old SBPro but not useless at all....


This is enough for now....  If U R 1 of the guys looking for a soundcard,
then U can C that U have a lot of hours playing while U R waiting for the 
Games supporting the REAL THING!!!

Subject: Problems with v1.21 software
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

More problems with UltraSound v1.21 software:

Alphabet Blocks, Sierra On-Line (Windows 3.1):

   This new Windows educational application was just released.  After
   introductory music the program hangs at the point where digitized
   speech is first used.  The only way to recover is CTRL+ALT+DEL.  When
   I removed the UltraSound driver and substituted the PC speaker
   "SPEAKR.DRV" driver the application functioned correctly.  Gravis
   technical support was not familiar with this new application or able
   to suggest a workaround.

Trax for Windows, Passport Designs (Windows 3.x):

   This MIDI recorder/sequencer when used with the UltraSound generates
   silence unless the necessary MIDI patches are first loaded into the
   Gravis board using another program.  This is the same cache problem
   reported in earlier digests with other Windows MIDI sequencers when
   used with the UltraSound.

Reader Rabbit 2, The Learning Company (DOS):

   No sound if SBOS driver loaded with "sbos -p", but sound works OK if
   driver loaded with "sbos".  Other DOS software I tried did work after
   "sbos -p".

   An earlier report of applications failing when the driver was loaded
   with "sbos -p" appeared in digest V1 #5.  Avoid the "sbos -p" option!

Gravis technical support line (604) 431-1807:

   Gravis installed a new voice mail system for technical support on
   Fri 27 Nov and it also has bugs. :-)

   The new system queues technical support calls, periodically
   announcing your position in the queue.  If you are still in the queue
   after 5 minutes it switches the call to the Gravis main switchboard
   where you are told that if you want technical support you must hang
   up and dial the same number which you dialed 5 minutes earlier!

   The main switchboard operator was clearly growing weary of technical
   support calls being redirected to her number.  After several cycles
   of hanging up, redialing, waiting in the queue for 5 minutes, and
   then reaching the main switchboard again, I finally convinced the
   operator to manually connect me to product support.

By far, 'Winjammer' is the best program for translating ROL files to MID files.
It translates tempo change, pitch wheel, volume changes as well as patch mappings.

Subject: Turtle Beach Multisound Specs
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

The board requires that you have a 386 (25 MHz recommended) with VGA
graphics, a fast (and large!) hard disk for direct-to-disk recording, 1.44
Meg floppy drive, 2MB RAM (to run Windows in enhanced mode?) and Windows
3.1 or 3.0 with MME (MME not included!).  The manual says you need only
have a 40 Meg HD, but that seems ridiculously small if you want to do any
CD-quality recording.  Also, the card uses a full length 16-bit slot, and
32k of upper RAM for the DSP (default is D000-D800, can use B000-B800).
Thankfully, the card will use one of the extended interrupts (default is
10).  I have a 20 Mhz 386DX with 10MB RAM, and a Quantum 120 Meg HD.  With
this configuration I can edit and play sounds without any problems
when recording at 44.1 kHz in stereo.  The hard disk does need to be
defragmented to maintain this performance level, however.

The Multisound hardware seems to be of a very high quality.  In addition to
a Proteus 1/XR on board, the card also has a Motorola 56001 DSP.
Electronic Musician (Aug. '92) claims the clock for this chip is 40 MHz,
and Turtle Beach confirms this.  The A/D is 16 bit, 64x oversampled while
the D/A is 18 bit, 64X oversampled, 1 bit sigma/delta.  The manual also
states that the D/A has an 8x interpolating filter.  The audio
specifications are given in three places, and have different values in all
three.  You can read EM and the back of the box yourself, so I will give
the stats listed in the manual.

	Frequency Resp.     DC->19 kHz +0/-0.2 dB
						DC->20 kHz +0/-2 dB
	S/N                 -89 dBV (A-weighted)
						-85 dbV (unweighted)
	THD                 < 0.005% (A-weighted)
						< 0.006% (unweighted)
	IM Distortion       0.01%
	Phase Response      +/- 0.5 degree
	Stereo Crosstalk    @100 Hz  -98 dBV (This is much higher than listed
										  on the back of the box!)
						@1 kHz   -76 dBV
						@10 kHz  -58 dBV

Well, all I can say is that whatever the numbers, the output seems most
musical.  I have done some sampling off CDs, and the results are
indistinguishable from the original.  In short, the output quality is most
musical.  The sampling rates are limited to 44.1 kHz, 22.05 kHz and 11.025
kHz.  Turtle Beach says the playback rates were fixed to these values to
improve playback accuracy.  The card has two external audio inputs (one for
recording and one to mix an external source with the card's output) and one
external output, and an internal audio connector for a CD-ROM drive.  There
is also a 9-pin D-shell connector for an optional cable with MIDI in, out
and thru ($24 extra).  This interface is not MPU-401 compatible.

The major piece of software included in the package is Wave Lite, a fairly
simple program that implements the hard disk recording features of the
Multisound.  It provides straightforward recording and simple editing
functions (cut, copy, paste) that are easier to use than the Sound Recorder
applet included with Windows.  It is possible to zoom in on the sample and
make precise edits, making it possible to cut the waveform near zero
crossings to avoid annoying clicks at the beginning and end of a sample.
The software also allows changes to be made to the waveform by drawing on
the screen with the mouse.  This drawing feature is not so easy to use,
however, since the mouse cursor does not exactly line up with the point
that is being drawn to on the screen.  

Wave Lite is not an application I would pay much money for, however.  As of
version 1.01, the program is very buggy, and invariably crashes within ~5
minutes of use.  It is still usable for small editing jobs, just not very
convenient.  I would not attempt a major job with the program in this
state, though.  Turtle Beach promises free software upgrades for a year, so
hopefully this situation will improve.

The manual and the program include advertising for the program's big
brother Wave for Windows, which is available for $79 + $5 S/H from Turtle
Beach (list price is $149).  The add promises various DSP manipulation
features including 3-D FFT representation of the waveform, 4 band
parametric eq., mixing of up to 3 sound files, crossfading, gain
adjustment, time reversal, time compression and expansion, sample rate
conversion, and support for file formats other than Microsoft's .wav files.

The Multisound package also includes a few other applets, all of which seem
bug-free, but which don't have much inherent utility.  Record Prep is a
dual VU-meter simulation that allows the recording levels of the card to be
set quite accurately.  The meters include peak level readings as well as
simulating the dynamics of a real VU meter.  The recording levels can also
be set from the Mixer applet, which also allows the relative output levels
of the various sound sources to be set.

Another applet is a facsimilie of the Emu Proteus front panel, which is
more cute than useful.  For those of you who have seen a Proteus (or own
one), imagine trying to do any serious work with it WITHOUT READING THE
MANUAL.  Thankfully, the Proteus manual is offered as an optional accessory
for $11.  The one innovation in the applet over the basic Proteus
functionality is the addition of a basic librarian function.  However, only
three banks are allowed, two of which are preset banks shipped with the
card.  The Proteus 1/XR factory presets are one set, and a General MIDI
patch setup is the other.  Even if I could program my own patches, this
simple librarian would not be very helpful.  I plan on using the sys-ex
librarian built in to Cakewalk for Windows for managing my patches.

Other than the diagnostics utility, the only other applet included is a
MIDI patch-bay.  This is useful if the external MIDI box is used, and can
allow the internal Proteus to respond to the external MIDI data stream like
a normal Proteus.  However, this disconnects it from the internal Windows
data stream.  It seems to me that the main advantage to having an internal
Proteus in my PC is that the Proteus is given its own data stream of 16
MIDI channels, but there are some situations where this capability might be
useful.

The Multisound driver supports simultaneous access from multiple Windows
programs, which is a very useful feature indeed.  For example, it is
possible to play a sequence on the Proteus, and simultaneously tweak your
patches using the the Proteus front panel applet.  On another note, the
Multisound driver allows independent access to the Proteus and each of the
two external outputs on the card.  This gives a total of 48 MIDI channels
out (16 to the Proteus, but it can use all 16) and 16 channels in.  With my
Music Quest PC-MIDI card (my MPU-401 compatible), I now have 32 channels in
and 64 channels out.  I don't need this much MIDI right now, but I doubt I
will need any more in the forseeable future.

The included documentation needs a bit of work.  The rather slim 37-page
manual for the card itself is unclear in places, and incorrect in others.
Thankfully, it is not really necessary for the use of the included Windows
applets.  Over a quarter of the manual is dedicated to an introduction to
digital recording, and while moderately useful this is not the most
important use for the user's manual.  The material included does not allow
a novice to become an expert, and is useless to anyone with a basic
understanding of sampling already.  Specifically lacking is any technical
documentation, especially how to program the on-board DSP.  No
documentation is provided for the Proteus synthesis engine at all, but it
is available in the form of the Emu Proteus manual offered for $11 extra.
This extra manual is required for all but the most casual use of the
on-board synthesizer.  Including the manual with the package to begin with
would have been much more convenient.

I have not heard of any third-party software being developed for the
Multisound.  The card is fully usable through the MME provisions of
Windows, but this leaves DSP applications out in the cold.  A developer's
kit is offered for the Multisound, but it does not seem to include any
support for programming the DSP.  Here is the response I got from Roy Smith
at Turtle Beach when I asked about the developer's kit:

>We have released the MultiSound Developer's Kit, which documents how to use
>the card from DOS or other OS, but this kit does not get into the DSP code.
>We plan to make a DSP developer's kit for it, but since this requires us to
>completely document our proprietary Hurricane architecture, we are unlikely
>to make the DSP kit widely available. In past meetings, I've heard that it
>will be available to OEM's who plan to purchase significant quantities of
>boards. If you like, I can fax you the table of contents of the dev kit so
>you can see what topics are discussed.
 
>This is not engraved in stone, and may change, but that's the current plan.
 
Well, it seems this means the DSP is off-limits to independent software
hackers, a major disappointment for me.  I am very doubtful that the
commercial market will produce the kind of synthesis software I am
interested in, and so I am stuck.  If you want access to the programming
interface for the DSP, please mail Turtle Beach!  Roy can be reached by
email at 75300.1374@compuserve.com, and the street address of Turtle Beach

friendly folks at Turtle Beach!  We just want to let them know there are
