The GUS will not produce a pop if the first note is decaying while the
second note begins.  This is what happens in real instruments.  When you
hit one key on the piano rapidly, each subsequent note will come in as
the previous note decays.  The GUS has no trouble with this at all.

The pops only occur when the first note is still in the constant-amplitude
sustain phase when the second note starts.  This never happens in real-life
even with an instrument of infinite time sustain such as the trumpet.
Blowing two C notes in succession will still mean that the first note
will be decaying before the second note begins.

Hi !

I've a problem with the installation of the SCC-1 card under windows.
I have tried to install it with the MPU-401 driver but when I 
install it, an error message occure (which says that there is
either an installation or an hardware error) and I can't use the
scc-1 with all windows programs (for example that utility where
you can use your soundcard to replace the PC-speaker in the case
of error messages).

Does anybody have the same problem or does someone has some hints ?
Does anobody have this configuration without any problems ?

Thank you in advance for any hints,

The error you received with the midi player means that it could not find
the specified instrument in your patch system ie)it is not listed in the
default.cfg file. You can overcome this two ways. #1, creat a cfg file for
the song you want to play and substitute instrument #64 for one that you
have that exists. #2, wait for the new and improved full patch set from
Gravis.

As far as detecting a full meg of ram on the gus, I am working on a
program that not only tells you how much ram is on your GUS, but also
tests it to make sure that the chips are all OK. Expect it very soon on
EPAS. If somebody does not beat me to it. (It is a very simple program to
write).

I may be missing something obvious, but I was just wondering...
If the GUS needs patches loaded into its memory, how on earth could you have
(even with 1MB onboard) more than a few short, CD-quality voices in memory at
the same time?  How could you, say, have a music file with 14.4K voices and
have any decent number of them at all?  ESPECIALLY without the memory
extension...  Even if it loads them dynamically, that must be
time-consuming... and what if you want to have 32 14.4K 10 second voices
going all at once?  They'd never fit!

My opinion:

The PAS-16 (Pro Audio Spectrum 16). It has a SCSI interface, 16-Bit, but a
little over $200. You might be able to find it for a good price though.
Check the latest "Computer Craft," they talk about the PAS-16 as well as other

I upgraded my GUS to 1 meg, but I still can't play a lot of the

10 (which is usually the drum track) the file will play, otherwise
it can't load all the patches.  I haven't modified my default.cfg

Keywords: gravis ultrasound gus memory map address conflict diamond video
Followup-To: poster

Yesterday I thought I had a possible I/O address conflict between my GUS
and the Diamond Stealth/VRAM video adapter.  The tech-rep at Gravis
(didn't get his name) stated that the memory map on p. 69 in the manual
was correct and that I would have a conflict.

After talking with Diamond today, I called Gravis again.  This time
I reached a "senior" person by the name of Harry Skibbe.  "Harry"
seemed infinitely more knowledgable than the guy with whom I spoke
yesterday and was, actually, quite entertaining.  When I asked him
about the memory map in the manual (version 1.1 by the way), he stated
that it was WRONG particularly the range 2X2-3X2.   "There's no way",
he said that they use such a large range.  Of course, this would
tromp all over most of the COM ports.  Harry said the correct addresses
should be in the README file.  Now, I have the 1.21 disks, but I don't
recall seeing a memory map in the README -- I'll definitely check when
I get home, BUT....  in the interim, if anyone out here happens to
have this information handy, PLEASE send me a copy!!!

Harry also commented about the available base ports.  On p. 16 describing
the jumper settings, the manual infers that only base addresses
210, 220, 230, 240, 250, and 260 are available.  However, on p. 69
describing the memory map, the manual infers that the 'X' can
represent 0-F hexadecimal.  Harry confirmed that, indeed, the card CAN
be configured to all of those (200, 210, ..., 260, 270, ... , 2F0) though
the ones shown on p. 16 are recommended as the others are much more
likely to cause a conflict.

The PAS-16 is capable of doing this because it actually has two ADCs
on the board.  I know for sure that you can use the PAS ADC to input
from the MIDI port and simulataneously play it on the Soundblaster ADC
(which is on the same board)...I have tried this personally.  You should be 
able to also use the Soundblaster ADC to read from the MIDI port and produce 
much better quality output (in stereo also) on the PAS ADC...I have never tried 
running both simultaneously myself, but I have used the Soundblaster ADC 
for MIDI and it works like a charm.  The only problem that you might 
encounter with using the Soundblaster ADC for MIDI is that the PAS16's 
Soundblaster hardware emulates version 1.5 of the DSP.  This means that you 
CANNOT do MIDI INPUT and MIDI OUTPUT at the same time...this shouldn't be a 
problem if you are using the other ADC to produce output.

But yes, the PAS16 can do what you want...

Yes, but this isn't the way real instruments work. If you hit a key on a piano
in rapid succession each note does get cut off - there's only one string (well,
maybe group of strings) associated with each key. Maybe the "right" way to do
this is bring the amplitude down very quickly, but not instantly, to make "room"
for the next note.

Linda,

You can probably order such a cable from Mediavision.  However, there are really
no special constraints on the audio cable other than that it use shielded
cable and the connectors fit.  There are basically only three wires required: 
left, right and ground.  And, the pinouts on the PAS16 are the same dimensions 
as on a standard IC DIP with the functions described in your PAS16 manual (odd 
pins all being connected to ground -- it has 5 pins).  So, if you or a friend 
is reasonably handy with a soldering iron you should be able to build it, 
getting the parts you need at a local electronics shop.

	I am going to purchase a sound board real soon here and I am not sure
if I should get the GUS or the PAS-16.  As far as I can tell the PAS-16 seems
to be better for midi.  I am looking for something that does SB, Midi, CDROM,
and 16bit 44KHz Stereo In/Out.

As far as I see..

Advantages to the PAS-16
-------------------------------------------------------------------------
o  16 bit Stereo 44.1 KHz in and out. (Available now!)
o  Good Midi Interface
o  "100% SB compatible"
o  Good CDROM support.  (Supports quite a few CD-ROMS)
o  $189 in Jan. Computer Shopper..

Advantages to the GUS
-------------------------------------------------------------------------
o  Cheaper ($129??)
o  On board RAM to load samples into. etc.
o  Wavetable sysths. is better than FM.
o  Sound better than SB!

Does the GUS have MIDI?
Does the GUS have CDROM?
How do they compare?
How soon will the 16 bit recording option be out? Any ideas on cost?

It seems that the best board to buy today is the PAS, but that perhaps the 
GUS will be the best to buy in a few months?  The software approach to 
simulating the SB has advantages and disadvantages.  Anyone care to comment
on which board you think is better?

Thanks.
