George Kirikos asked if anyone knew if Gravis had signed an agreement with
Archer for their Q-Sound technology.  I don't know the answer to this, but
I do know that Q-Sound is not the only form of 3D signal processing.  In
fact, there are several different types by different companies, though I
don't have the foggiest what the others are, except for B.A.S.E.  I like
BASE a lot, and prefer it to the clogged-up-ear effect Q-Sound delivers.
My Q-Sound recordings:
   Madonna - Justify My Love US CD5
  I've also heard the Immaculate Collection and that last Sting album

My BASE recordings:
   Orbital - Orbital US CD
   Orbital - Mutations UK 2x12"
   Tangerine Dream - The Park Is Mine soundtrack US CD

Believe me, you don't want Q-Sound if you've heard BASE.

(digging through files...)

Someone on the net gave me this information:

I checked the article and it does indeed mention the Bedini Audio BASE
system. The details of what it does were not revealed by the manufacturer,
but they say it is 'more a psychoacoustic enhancer than a localization
synthesizer;. The signal is broken into center channel (ie. mono) and
stereo (ie. left or roght channel only) signals. The center image can be
moved nearer or further and the stereo componenet's gain can also be
increasd or decreased to widen or narrow the  soundstage. The original
signal is then re-added (after being pocessed) resulting in 'a more
clearly placed image within a broadened soundfield that can be perceived
outside of a specific sweet spot.'. You can contact the manufacturer at

Hello all,

I just received email that Accolade has had numerous reports of the GUS 1MB,
and Star Control 2 BUG. They have been unaware of this and are now looking
into the problem.

Great JOB to all those that called and emailed!!!!

[This will probably be one of countless dozen responses to your query. :-)]

The Ensoniq.  Hm, where do I start?

The full name is "Ensoniq 5503 Digital Osciallator Chip" (DOC for short).

At the most basic level, the Ensoniq simply plays back digitized or
synthesized waveforms.  There are 32 'oscillators', each of which can
play part of a waveform, giving you a maximum of 32 voices, but with
limited capabilities.  By pairing the oscillators, more flexible
operation is possible.  A pair of oscillators is termed a 'generator'.
Using generators, a maximum of 16 voices are available.

You have up to 16 output channels.  All channels are multiplexed onto
a single sound output, with a channel number available in parallel for
external demultiplexers.  (The IIgs is limited to 8 output channels.  A
stock IIgs has mono output, but third-party stereo cards are available.
I'm not aware of any cards that support more than two channels.)

Each oscillator has:

- volume register, used to attenuate the waveform
- frequency register, used to vary the playback rate.
- control register, used to set the operation mode, interrupt mode, and
select the output channel.
- wavetable size register, used to set the size of the waveform and
the resolution of the table.

The Ensoniq has dedicated RAM, accessed in a dual-port fashion.  The
computer writes wavetables into the RAM, then uses the DOC's registers
to control the operation of each oscillator.  More than one oscillator
can play the same waveform at the same time, using different register
settings if desired.

The IIgs has 64k of sound RAM, but the Ensoniq can support 128k.  The
maximum size of a single waveform is 32k.


Playing back a digitized sample requires no computer overhead (except
for copying additional portions of the sample into sound RAM).  Far
more complicated operation is possible, with the computer dynamically
adjusting the Ensoniq's volume and frequency registers to simulate a
typical envelope generator, and to play different notes using the same
instrument.


That covers the basics (but I've hardly done it justice).  No doubt
more will be revealed...

Subject: FAQ candidate: no MIDI sound under Windows
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

Q: I'm not getting any sound when I play MIDI files under Windows.  The
   Patch Manager shows empty boxes.

A: There is a file in the distribution set called ULTRASND.INI.  It must be
   placed in the directory pointed to by the environment variable ULTRADIR
   (usually C:\ULTRASND).  It does *not* go into the WINDOWS or WINDOWS\SYSTEM
   directory.

   If you have ULTRASND.INI in your ULTRADIR directory, look at it.  It 
   should have many lines in it saying things like "0=acpiano1".  If it is
   only a few lines long, get another copy out of the distribution and copy 
   it to the ULTRADIR directory.  Reboot Windows and you will soon be hearing 
   beautiful music!

   (The purpose of the ULTRASND.INI file is to let the Windows driver know
   what patch file goes with what patch number.  If the driver doesn't find
   the .INI file in the ULTRADIR directory it creates a truncated version 
   with no patch names in it.)

I called Chris Yuzik at Gravis and he told me a couple of things. First, it
is ALL software. As he put it, folks were speculating about what to do with
all those 32 digital pannable channels. Well, he knew this was the answer,
but was unable to comment due to business issues, such as premature
annoucements and all that. The other bit of info was that the press release
that is being circulated differs slightly from the "real" release in that
it doesn't mention that the sound designers have to do some retooling of
their sound tracks to take advantage of this new stuff. They have to define
the size of the sphere around the user and then place the sounds within it.
Gravis has some demos (things such as a fly buzzing around the user and
such). So, we can look forward to this in the future, but it won't just
"work" with existing games.

He also told me the Windows driver is "almost done", the MIDI box and
16-bit daughterboard are now slated for April (yikes!) and they should be
shipping the General MIDI patches soon.

As I understand it, GUS 3D isn't Q-sound, since the sound is processed in
realtime by the board. But I could be wrong...

Subject: GUS: Working MIDI connectin circuit.
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

I have used the followin circuit to connect to the Ultrasound to get the 
MIDI port working. This has been posted before but to get it to work I
had to change one of the resistors, namely the pullup resistor connected
between pins 6 and 8 of the optoisolator I also used 6N138 insted of 6N135
(I couldn't get it at the time). Also the inverters have to be able to work
at a high speed (i think midi is around 19000 but I am not sure), one of the
inverter chips I used didn't work even though the chip was fine, I gues
it could not handle the speed.
I then tested the port by playing something on the keyboard and listening
back to the seqence, the timing seemed ok. to make sure I installed a
Roland MPU 401 card into the pc and connected its midi out to the midi in
of the Gravis. I then used one sequencer to play something out of the Roland
port and another sequencer to record with the Gravis port. Then I listened
to the recorded sequence by playing it first through the Gravis midi out
and the through the Roland midi out, both sounded exacly like the original.

Anyway I hope this will be useful to someone, I for one am happy to have
the Gravis midi port working (for the fraction of the cost of what the
SB connector box costs).

To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

The MIDI connector box for the GUS will not be out for a while, the
work with it at Gravis isn't proceeding too fast. However, a
relatively easy and inexpensive way - that works - is to use an SB
connector kit and replace the 6N136 chip with a 6N138 or -139. In
addition, add a 5.6K ohm ressistor between pin 5 and 7 on the chip,
and one between pin 6 and 8. This definitively works, I'm using one
myself!

Happy soldering,

Thank you!  I have been trying to understand why you and a couple of others
were reporting this problem, but I couldn't reproduce it.  You've figured 
it out for me - I don't have WHOOP running.  The Windows driver indeed 
doesn't like to open the MIDI device while a .WAV file is playing (don't 
know why, I'll ask) and WHOOP would almost certainly cause the behavior 
you are describing.  

There is a minor upgrade of PatchMgr (v1.03) being packaged for release as
we speak.  In this version, if the MIDI device is not available when it is
being activated, PatchMgr posts a message but does not exit.  This should
reduce your problem from pain-in-the-butt to minor annoyance.

Meanwhile, I will see if the WAV/MIDI conflict can be eliminated or at least
worked around better.

Thanks for your feedback.

To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

-- PLAYMIDI --

PLAYMIDI v3.21 Nov 02 1993 - came with my 1.21 install disks, had 
consistent bad note problems with certain midi songs like scdemo #4.

PLAYMIDI v3.40 Jan 04 1993 - found on epas called PLAYMIDI.ZIP.  Fixed 
problems with bad notes in scdemo #4, and added a high resolution 
graphics display similar to playmidi -udebug (no command line option; 
it's automatic) which displays midi tracks, notes, and volumes.  Also 
added some more parameters.  However, it also seems to have a serious
bug -- at a random point in a song, playmidi will just crash and
sustain whatever notes it was playing at the time.

PLAYMIDI v3.50 Jan 06 1993 - found embedded in the new 1.22 install 
disks on epas.  Removed graphical midi display found in 3.40.   Also
seems to have removed the serious "sustain" bug.  Playmidi -h now pauses 
for a keypress after a screen full of parameters.

-- PATCH MANAGER --

The PATCHMGR.ZIP on epas is V1.01, and I found a v1.02 embedded in the
new 1.22 install disks.  I noticed a much nicer Audition menu option.  
I use TRAX with Windows 3.1 and the PatchManager is just great.  Hopefully 
Passport will also jump on the WinJammer Patch Cache bandwagon soon.  
PatchManager itself seems to be a very intuitive and well thought out 
program that is great for auditioning patches!

-- SBOSDRV.SYS --

There is also a non-beta SBOS v1.22 floating around epas.  (GUS0011.ZIP)
It came with its own SBOSDRV.SYS, and has the same problems with  Jill of 
the Jungle.   It appears that the problem definitely isn't SBOS v1.23 but 
how Gravis/Forte makes their SBOSDRV.SYS.  (To summarize my previous post: 
certain games crash if you use SBOSDRV.SYS with LOADSBOS.EXE.  If you use 
SBOSDRV.EXE with LOADSBOS.EXE, these same games worked perfectly fine.)

To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

Don't know if anyone cares, but I thought I'd post that Sting's 
album "Soul Cages" features Qsound, and has a little mini write up 
about it inside.  I think I heard (probably here) that Maddonna's
"Immaculate Collection" has it too.  Anyone know of others - I'd 
like to check 'em out.  
I can't believe this semester's books cost me $357.  Simply can't.

Subject: Spectrum Holobyte and GUS
To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

Hi all,

I just finished an exchange of mail with Spectrum Holobyte tech support asking
whether there was a way to support the GUS under Tetris Classic/Windows (they
use hard-wired drivers rather than Windows drivers, apparently so they can
support Windows 3.0).

Anyway, they suggested using SB mode on the GUS and commented that it was a
"great sounding card".  On my reply, which explained that SBOS does not run
under windows I asked if his knowledge of the card's quality implied upcoming
support.  He replied that they were considering supporting the GUS, but their
sound drivers are written by another company and they needed to wait for this
other company.

So all is not perfect, but things are looking up for GUS support at least.

I wonder if this "other company" writes sound drivers for lots of companies.  If 
so, they would be good folks to lobby with/help!  If we knew who they were!

To: Ultrasound Daily Digest <ultrasound@dsd.es.com>

	 Hey, I just got Star Control II and I must say that I'm really
impressed.  There is over an hour of different songs and the sound affects
are nice and clear (if only I didn't get to hear my ship blowing up so often
:)).  I haven't upgraded to 1 meg on my card so I haven't had any of the
problems that other's have been complaining about.  I do have one question
that I hope someone can awnser.  

	 Is there a way to control the Ultrasounds volume when it's working in
native mode?  I just run two speakers off of the amplified output and for
most SBOS applications it's fine but ST II is REALLY LOUD.  I mean REALLY
LOUD.  I've taken to using my earphones out of the regular output and even
then I slide the pad way up on my cheek bones because it's to loud.  If you
know how to change this please write and let me know.  I'm sure many of us
would be interested.  Thanks

I think it would be nearly impossible implementing Q-Sound (assuming that 
GUS3D will be using Q-Sound or a derivative thereof) on the SB/SBPro/
PAS-16/etc. since:

  1.  The FM synthesizer may not give enough control over the phase of the
	  waveforms.
  2.  Using digital samples pumped through the dumb dac would be way too
	  cpu-intensive.  It can be done, but would we have real-time 
	  positioning of sounds and still have enough clock cylces left for
	  games?

I also think that Q-Sound would be just as hard to implement on the 
upcoming Aria cards since they are ROM-based.  The samples need to 
preprocessed and uploaded to the card, so RAM is a requisite.  The Arias
have a DSP, but it's not used for wavetable synthesis in any way as far
as I can tell.  It's only for SB emulation and 1- or 2-channel sample
decompression.  To operate on the wavetable voices, it would need to be
able to process 32 channels "simultaneously".  Thus, the DSP won't be 
able to process the ROM samples on-the-fly to obviate the need for
preprocessed samples.

Actually, it is not version 2.3, it's version 2.23.  I think that explains
the designation above.

The program also has a slightly different look to the interface.  I like it
better than the previous version I had.

Hi all!
 I discovered this one on cica.cica.indiana.edu in the uploads
subdirectory. I checked it for viruses, it appears clean. I tested
it last night, it works alot like mmjbox, but it can continually
loop through the list of selected MIDI files. I like it :).
 That's all for now .... have fun .... and be careful out there :).

I was at the CES show in Las Vegas last week/weekend, and visited the
Gravis booth.  I listened to a demonstration that was absolutely mind-blowing.
The guy hands me a pair of headphones.  I put them on.  I am facing the booth,
and I start to hear crickets in front of me.  They sounded very real, but
then the guy motioned for me to turn around in place.  I began to turn to my
left, and the crickets location STAYED in the SAME place!  I turned all the
way around, 180 degrees from my original direction, and the crickets were
absolutely behind me.  

I began to think about my experience later, and decided that what I had heard
was impossible.  So, I pulled out the Gravis business card and gave the guy
a call that had demonstrated this to me.  He explained that the headphones
I was listening to were indeed normal, everyday headphones, with one exception.
There was a magnetic sensor attached to the headphones to give feedback to the
demo program as to my head position. 

He also said the Ultrasound 3D should be shipping in late Feb or March.
No word on price
