GRAVIS GrIP TECHNOLOGY BRINGS MULTI-BUTTON, 4-PLAYER ARCADE
|
|
GAME ACTION
|
|
TO THE PC. Gravis GrIP digital game interface technology levels the game
|
|
platform playing field, then blows the other players away! With the new
|
|
GrIP Game System from Gravis, you get the four-player, multi-button
|
|
support and blazing arcade speed that have become common on the newer
|
|
game console platforms_but on your PC.
|
|
|
|
What is it exactly? The GrIP MULTIPORT is an adapter box that connects
|
|
to your PC game port with a standard D-15 connector. On one side, the
|
|
MultiPort has two D-15 pass-through connectors, so it is backward-
|
|
compatible with all your older joysticks. The MultiPort's other wing has
|
|
four D-9 connectors for GrIP controllers. These GrIP ports are digital
|
|
and allow two-way digital communication between your game port and
|
|
attached controllers. What does that mean? First, it means SPEED. A
|
|
standard game port uses 12 to 15% of the CPU's cycle time to read the
|
|
position of a single joystick. The GrIP MultiPort uses less than 1% of
|
|
the cycle time to read four controllers. That means faster game
|
|
performance. The MultiPort's two-way communication also gives you auto-
|
|
calibration.
|
|
|
|
Even more exciting for the future, the MultiPort supports "virtual
|
|
reality" control features that you could be seeing in upcoming GrIP
|
|
controllers_like 3-D and 6-D controls, tilt, tactile force-feedback, and
|
|
velocity-sensitive buttons: for instance, one day you'll be able to kick
|
|
hard, kick soft, kick anywhere-in-between in your PC soccer game by
|
|
using a harder or softer touch on the buttons.
|
|
|
|
The GrIP Game System also includes two 8-button digital GrIP-Pad
|
|
controllers (extra pairs of GrIP-Pads are available separately). In
|
|
games that support GrIP, the MultiPort supports all eight buttons on
|
|
each of up to four GrIP-Pads at one time. In Windows 95, and in games
|
|
that you can run from a Win 95 DOS box, the GrIP-Pads are programmable
|
|
for keyboard controls, too. So in games that don't support GrIP
|
|
directly, you can still use custom controls. Or you can choose to use
|
|
the GrIP-Pads in GamePad Emulation mode, emulating a standard PC GamePad
|
|
with a choice of control styles for arcade or driving games.
|
|
|
|
A Gravis GrIP MultiPort driver is built into Windows 95. GrIP works with
|
|
every Win 95 DirectInput game automatically, and support for GrIP is
|
|
also built into new titles from Electronic Arts, Virgin Interactive
|
|
Entertainment, Acclaim Entertainment, and MINDSCAPE. Gravis provides
|
|
active support for game developers, so you'll be seeing GrIP support in
|
|
all the best new games.
|
|
|
|
The GrIP Game System is available now in two $99.95 software bundles:
|
|
the ultimate Team Sports Set with a special GrIP edition of EA SPORTS
|
|
NHL Hockey 96 and the ultimate Fighting Machine with the full version of
|
|
Acclaim's WWF Wrestlemania. You can also pick up the GrIP Game System
|
|
without bundled game software ($79.95) or an extra pair of GrIP-Pads
|
|
($29.95) direct from the Gravis Mail Order System.
|
|
To order yours, call 1-800-257-0061.

NO PROBLEM!
|
|
|
|
Today's Topic: 4 Common PC GamePad Questions
|
|
________________________________________________________________________
|
|
|
|
|
|
1. What's the GravUtil program for?
|
|
|
|
Your GamePad does not require DOS drivers or any other software. The
|
|
Gravis Utilities (GravUtil) software on CD (or Disk) is for testing
|
|
only. If your GamePad works, you don't need GravUtil.
|
|
|
|
2. Why do only two buttons work?
|
|
|
|
The game port you are using probably supports only two joystick buttons.
|
|
This is a common limitation with the game ports on multi I/O cards. What
|
|
do you do?
|
|
|
|
If you have a sound card in your computer:
|
|
|
|
- Try disabling the game port on the multi I/O card (see the hardware
|
|
manual for instructions - there's usually a jumper for this).
|
|
|
|
- Next, enable the sound card game port (see the sound card manual for
|
|
instructions - there is often a software switch to enable/disable the
|
|
game port).
|
|
|
|
- Then plug your GamePad into the sound card's game port. These usually
|
|
support four buttons and four axes.
|
|
|
|
If you don't have a sound card, you can purchase a dedicated game card
|
|
like the Gravis Eliminator that supports four buttons and four axes.
|
|
|
|
3. Why won't Windows 95 recognize my GamePad?
|
|
|
|
If you have a Joystick icon in your Win 95 Control Panel, all you have
|
|
to do is select it and choose "Gravis PC GamePad" from the list.
|
|
|
|
If there's no Joystick icon in the Control Panel, you have to install
|
|
Microsoft's Gameport driver first:
|
|
|
|
- Choose Add New Hardware, and select NO at the "search for new
|
|
hardware" prompt.
|
|
|
|
- Select Sound, Video, and Game Controllers.
|
|
|
|
- Select "Microsoft" as the Manufacturer and "Gameport Joystick" as the
|
|
Model.
|
|
|
|
- Click the Finish button. A Joystick icon should now be present in your
|
|
Control Panel.
|
|
|
|
4. Why do I get the message "Joystick is not connected properly" when I
|
|
try to calibrate my GamePad in the Win 95 Control Panel?
|
|
|
|
- Check the game port connection.
|
|
|
|
- Make sure you've selected Gravis PC GamePad in the Joystick setup.
|
|
|
|
- Use GravTest to check that the game port is active.
|
|
|
|
- Use Device Manager to make sure the input range of the Microsoft
|
|
gameport joystick driver is 0201-0201. If not, remove and reinstall the
|
|
driver.
|
|
|
|
NEED MORE HELP?
|
|
|
|
If you have the new GravUtil on your system (the version with pictures
|
|
of the GamePad and joysticks on the main screen), run it, and look in
|
|
its Help file for the info you need.
|
|
|
|
If you have the older GravUtil (the one with 3 text options on the main
|
|
screen), download the file pcgphelp.txt (in the \FILES\PC\JOYSTICK\JOY-MISC
|
|
directory on the FTP site. Or download the new GravUtil (grvutl4.zip, in the same
|
|
directory).

MYSTERIES OF MIDI
|
|
- Curtis Patzer
|
|
________________________________________________________________________
|
|
|
|
The UltraSound Plug and Play (PnP) is Gravis' great new sound card. It
|
|
does everything other UltraSound cards do*, and more: it supports multi-
|
|
layered patches with up to 16 envelopes and onboard effects; and it
|
|
supports up to 8MB of external SIMM RAM which can be used to store
|
|
custom patches (the small sound and instrument samples used to produce
|
|
wavetable sound).
|
|
|
|
*Note: The UltraSound Plug & Play card requires at least 512K RAM to
|
|
make it compatible with software written for the older UltraSound cards.
|
|
|
|
************************************************************************
|
|
There's some technical stuff here. If you're a novice, start with your
|
|
UltraSound manual, play around with Cakewalk Express or another MIDI
|
|
sequencer, and come back here later. If you're a MIDI whiz, dig in! -ed.
|
|
************************************************************************
|
|
|
|
A Tale of Two MIDIs...
|
|
|
|
The UltraSound PnP supports two completely different MIDI patch formats:
|
|
the GF1 patch format (used by classic UltraSounds - meaning any Gravis
|
|
card before the UltraSound PnP), and the new InterWave patch format.
|
|
These two formats are not compatable with each other. This means the
|
|
UltraSound PnP can play patches from only one format at a time.
|
|
|
|
How do you switch between patch formats? If you want to use GF1-style
|
|
patches, you need to load GF1 (classic UltraSound) drivers for Windows
|
|
3.1 or Windows 95. If you want to use InterWave patches, you need to
|
|
load InterWave drivers for Windows 3.1 or Windows 95. Note that you
|
|
cannot use both drivers at the same time with the same card. (It is
|
|
possible to install and use both an UltraSound PnP and a classic
|
|
UltraSound card in Windows 95, though, as long as the SoundBlaster
|
|
device for the PnP card is disabled.)
|
|
|
|
When the UltraSound PnP is used with classic UltraSound drivers, it has
|
|
all the same limitations as classic UltraSound cards: 1 MB of memory and
|
|
up to 32 voices, depending on the sampling rate. To configure the
|
|
UltraSound PnP this way, you must specify the same environment settings
|
|
as you would for a classic UltraSound card, as well as the INTERWAVE
|
|
environment variable. You must also run iwinit.exe before running
|
|
Windows with the classic GF1 drivers, or running DOS mode games. In this
|
|
configuration, you can use Patch Manager and Patch Maker Lite with GF1
|
|
patches. Here's an example of what this configuration would look like in
|
|
autoexec.bat:
|
|
|
|
set INTERWAVE=c:\ultrapnp\iw.ini
|
|
REM ===== Gravis initialization (4.10) =====
|
|
SET ULTRASND=220,7,7,12,5
|
|
SET ULTRADIR=C:\ultrasnd
|
|
REM ===== Gravis initialization ends =====
|
|
c:\ultrapnp\iwinit.exe
|
|
|
|
For this to work, the Plug and Play setup for the PnP card must set
|
|
manually to the same settings as shown on the ULTRASND= line above. This
|
|
can be done either in the driver control panel, or in the InterWave
|
|
initialization file named in the INTERWAVE environment string (iw.ini in
|
|
the above example).
|
|
|
|
When the UltraSound PnP is used with the InterWave Windows drivers (the
|
|
ones that ship with the card), then InterWave patches are used
|
|
exclusively. These patches can be located either in the card's ROM, or
|
|
loaded into the card's RAM (the Pro version of the card comes with 512K
|
|
of RAM; both versions of the card have two SIMM slots for adding up to
|
|
8M of RAM using 32-pin SIMMS). The InterWave initialization file
|
|
(IW.INI) has a section for configuring which ROM and/or RAM patches are
|
|
used for MIDI. (More on customizing the IW.INI file later.) It is
|
|
possible to load ROM patches, and custom RAM patches at the same time.
|
|
Of course, to load RAM patches, you must have some RAM on your
|
|
UltraSound PnP card. Also, be aware that it is possible to use a
|
|
combination of patches with a combined size larger than the size of
|
|
available RAM, since RAM patches are cached. (This is the same principle
|
|
that allows a classic UltraSound card with only 1MB of onboard RAM to
|
|
use a 6 MB patch set.) As always, patch caching performance improves
|
|
with more RAM.
|
|
|
|
InterWave patch files (.FFF) may - and usually do - contain more than
|
|
one patch. Also, sample data is often stored in separate .DAT files.
|
|
Both types of files are necessary to successfully load InterWave
|
|
patches. In fact, you can put an entire General MIDI patch set into just
|
|
one (HUGE) InterWave patch file.
|
|
|
|
Because the InterWave Windows drivers support multiple banks (using
|
|
Control Change 0h and 20h), it is possible to access several banks of
|
|
patches at the same time without a bank manager. To do this, you must
|
|
configure the InterWave initialization file to use all the desired
|
|
banks, and then use a sequencer or MIDI player which can send the
|
|
required MIDI bank selection messages to load the desired patches.
|
|
|
|
A special feature of the Windows 95 InterWave drivers is the ability to
|
|
mimic a classic UltraSound in a DOS box. This makes it possible to play
|
|
DOS games that support the classic UltraSound sound cards.
|
|
|
|
WHAT NOW?
|
|
|
|
Gravis recently released a utility called GIPC, which stands for Gravis
|
|
to InterWave Patch Converter. GIPC converts groups of classic UltraSound
|
|
patches to the new InterWave format. Once the InterWave initialization
|
|
file is modified to use the new patches, they can be loaded and played.
|
|
GIPC is not meant to be a patch editor - it is a converter only. As
|
|
such, it cannot access the advanced features that the InterWave patch
|
|
format offers, but it does provide a quick way to port existing GF1
|
|
patches over to the new InterWave format. You can use Patch Maker Lite
|
|
or another GF1 patch editor to create GF1 patches, and then convert them
|
|
to InterWave patches using GIPC. Make sure you read the readme file
|
|
before using it.
|
|
|
|
IN THE FUTURE...
|
|
|
|
Gravis is working on a professional, full-featured Windows 95 patch
|
|
editor for InterWave (and possible GF1) patches. This application will
|
|
make the full InterWave patch feature set available to the user. It will
|
|
also support conversion from GF1 to InterWave patch format (and possibly
|
|
from InterWave to GF1), and easy patch/bank configuration setup in the
|
|
InterWave initialization file. Look for a first release in the first
|
|
half of 1996.
|
|
|
|
MORE ABOUT THE INTERWAVE INITIALIZATION FILE
|
|
|
|
Even without an InterWave patch editor, you can specify patch and bank
|
|
switching if you know how to edit the InterWave initialization file
|
|
manually. Here's how:
|
|
|
|
The name of the InterWave initialization file is indicated by the
|
|
INTERWAVE environment variable (e.g. INTERWAVE=c:\ultrapnp\iw\iw.ini).
|
|
For this discussion, we'll assume the InterWave initialization file is
|
|
called IW.INI (the default name).
|
|
|
|
The format of the IW.INI file is similar to the format of the
|
|
configuration files that Microsoft uses for its Windows products. The
|
|
file is split up into sections. The beginning of each section is marked
|
|
with a line with the format
|
|
|
|
[text]
|
|
|
|
Each line in the configuration file that is not a section header is
|
|
either a blank line, a comment line, or a line containing information
|
|
needed by the InterWave software. Comment lines, which start with a
|
|
semicolon, and blank lines are ignored by programs processing the
|
|
configuration file. The configuration file contains sections for saving
|
|
mixer options, patches, chip setup and sound card emulation (SBOS)
|
|
options. We'll look only at the patch section.
|
|
|
|
The InterWave software does not have to assume a specific set of MIDI
|
|
patches will ship with the UltraSound PnP card. The configuration file
|
|
allows for mixing of different patches from different sources,
|
|
whether they be in ROM, RAM, or some in each. A description of a patch
|
|
configuration starts by listing the patch files and assigning a name to
|
|
the list. For example, assume the patches are in three files a.fff,
|
|
b.fff and c.fff. An entry describing these patch files would be found in
|
|
the [vendors] section.
|
|
|
|
[vendors]
|
|
favorite=a.fff, b.fff, c.fff
|
|
|
|
Some of the patches in the configuration files may be redundant. The
|
|
InterWave software will choose the last patch it finds in the list. For
|
|
example, if a music score is looking for a piano, and the piano patch is
|
|
in both the c.fff file and the a.fff file, the software will choose the
|
|
patch in c.fff.
|
|
|
|
The location of the patches is determined by checking the filename. If
|
|
the first three characters are ROM, then the filename is used to search
|
|
for the appropriate set. If the first three letters of the filename are
|
|
not ROM, then the configuration file is searched for a section labelled
|
|
[vendor tag] where tag is the same tag used to identify the patch files.
|
|
For example, the section to locate the patches described above might be:
|
|
|
|
[vendor favorite]
|
|
a.fff=c:\patches\a_set
|
|
b.fff=d:\patches\more\b_set
|
|
c.fff=n:\public\sharwar\patches\c_set
|
|
|
|
Each patch file is listed on a separate line with the path to that file.
|
|
The path is also used to locate any sample data associated with the
|
|
patch file.
|
|
|
|
By default, the UltraSound PnP uses the 1MB ROM patch set. In that case,
|
|
the patches section looks like this:
|
|
|
|
[vendors]
|
|
rom_amd_1m=ROMAMDGM_1_1_
|
|
default = rom_amd_1m
|
|
|
|
Because the patches are in ROM, there is no file path, and thus no
|
|
[vendor rom_amd_1m] section.
|
|
|
|
Now, say you wanted to add some patches that you converted using GIPC,
|
|
and they are in a file called GIPC.FFF. If you wanted to use only the
|
|
newly converted patches (and no others), you would setup the patches
|
|
section as follows:
|
|
|
|
[vendors]
|
|
rom_amd_1m=ROMAMDGM_1_1_ ; this is the original ROM-only
|
|
configuration
|
|
gipc=gipc.fff ; add this line for the new
|
|
configuration
|
|
default=gipc ; this line shows which configuration
|
|
is chosen
|
|
|
|
[vendor gipc]
|
|
gipc.fff=c:\gipc\destdir ; where the new InterWave patch file

If you wanted to combine the ROM patches and your patches, with your
|
|
patches taking precedence over the ROM patches, you would setup the
|
|
patches section as follows:
|
|
|
|
[vendors]
|
|
rom_amd_1m=ROMAMDGM_1_1_
|
|
rom_and_gipc=ROMAMDGM_1_1_, gipc.fff
|
|
default=rom_and_gipc
|
|
|
|
[vendor rom_and_gipc]
|
|
rom_and_gipc=c:\gipc\destdir
|
|
|
|
If you modify the InterWave initialization file, you must reboot for the
|
|
settings to take effect.
|
|
|
|
Until next time, don't stop the music!
