Here is a quote from the Ultrasound Developer's Toolkit: "There are 15 pan
positions for each voice." There you have it. Fully panable. Star Control II
uses this panning; 1 music channel is mixed far left, 1 is mixed "mid left",
1 is mixed "mid right" and the last is mixed far right.

Has anyone had this problem?

  When I start Ultima Underworld I hear a voice being played back
REALLY REALLY fast.  Maybe it's the "At last you are asleep" thing.

  Anyway, it goes on doing this until the voice is supposed to start,
as though the GUS had recieved instructions to play back something in
its memory and it goes on doing this until it's told to do otherwise.

  I can live with this, since it can be stopped by playing through the
first few words of the introduction, but what REALLY bothers me is
that there is a small "tick" after every couple seconds of speech
everywhere.

  I've messed with my EMM386 settings so it had "512 M9 AUTO
X=C800-CBFF RAMF" and subcombinations (gravis told me to try this).
Does anyone have any IDEA what's wrong (even if you don't know how to
fix it)?  I have no apparent problems with DMA channels (I'm using 5)
or system hangs, etc.

Morgan (an otherwise very happy GUS owner :-)

Well, I know people hate this type of answer, but... "It works for
me!".  Suggestions:  if you have SBOS 1.20, use SBOS -O2.  If you have
1.22, it should be working.  Is your SET BLASTER variable set up
correctly?  Are you running at least version 1.1 of Wolf 3D?

The same thing happened for me when I owned my soundblaster!

SBOS only used 256K, for anything not in native GUS mode 256K should
be enough.

Has anyone used the PAS-16 with a MIDI interface?

I have been using mine with a homemade interface and I hear some
digital noise comming through on the left side.  Any midi commands
(keyboard press/release) cause a slight 'click' to be heard.

Has any one else had this problem using Media-vision's overpriced
Midi-Mate (tm) ?  Do they do some magic to reduce the crosstalk from
the digital to the analog section?

MV tech support is most useless on this matter.

Go into configure midi... and add the Ultrasound driver to the configuration.
You must also remember that WinJammer doesn't support patch caching, so you
will have to load in the patches for a song by playing it with Media Player
first.  (To play the song with Media Player, you must make sure that 
WinJammer isn't configured for the Ultrasound.  After the song starts,
you can stop Media Player immediately, as all the patches would have been
loaded.  Then configure WinJammer for the Ultrasound.)

BTW, if you have an older version of WinJammer that doesn't support
Win 3.1 multimedia extensions, then none of what I've suggested will
work.

I have Winjammer working fine at home. Only problem being I had to load
the patches using media player first though... that is until the new

Don't recall seeing this message at all. I'll check when I get home...
that is unless someone else answers first.

It has something to do with a floating ground, or ground currents.  I.e., you've
got a poor ground, or some wires or something is connecting electrically

	I'm sure it's not screwed up.  Gravis added the switch to PLAYMIDI 
for their own information on debugging the software or the card.  Notice 
that that information is not included in the manuals.  Looks like we shouldn'

I think what he meant was that the GUS generates sounds via wavetable synthesis.
The loading of patches into the RAM has more to do with the midi songs 
and also used in the SB emulation. The GUS can also operate as 32 channel DACs
for playback of straight digitised sound...

Doubt if general midi will be the next standard. With more wavetable cards
coming to the market, all with on board ram(and some with rom too), most
game makers would probably opt to use their own patches and samples to go
with their games.
