FOR IMMEDIATE RELEASE:

  ADVANCED GRAVIS AND HOWLING DOG SYSTEMS SIGN LICENSING AGREEMENT

Advanced Gravis Computer Technology Ltd. and Howling Dog Systems
have signed an agreement whereby Howling Dog's music software will
be bundled together with Advanced Gravis UltraSound(tm) multimedia
PC hardware.  The world-wide, non-exclusive licensing agreement
extends to the end of 1993.

Under the terms of the agreement, Gravis will license Power Chords
for Windows and a collection of MIDI songs for inclusion in the
retail versions of the Gravis UltraSound sound card.  The bundle
will give users the ability to easily play, edit and compose MIDI
music for personal, business, or educational purposes using a
familiar guitar interface and powerful drum kit.

"A large percentage of our sound card customers are Windows users
anxious to experiment with music composition," Grant Russell,
Advanced Gravis president.  "These customers are going to find our
CD-quality sound and Howling Dog's revolutionary software hard to
beat, especially at the price."

Gravis UltraSound, released in early October 1992, is a 16-bit    
44.1 kHz, 32 voice stereo sound card with support for Standard
MIDI, 256K of on-board memory, and a speed-compensating game port. 
UltraSound features wave table synthesis for true professional
quality musical instruments reproduction.  It features Ad Lib(tm)
and Sound Blaster(tm) compatibility and supports Windows Multimedia
Extensions.  The suggested retail of the UltraSound bundle is
$199.95 and will began shipping in January 1993.

Power Chords for Windows is a object oriented music sequencer that
makes use of a playable on-screen guitar as one of its input
metaphors.  Users can create chord objects, strumming patters, drum
parts, melody and base parts, all with the mouse.  Compositions are
created by dragging the various parts into position in a song
framework.  This interactive approach to music making shows the
true power of the Windows environment.  Power Chords also supports
standard midi functions.  Amateur musicians and hobbyists with a
knowledge of music can use the software to compose, play and record
original music.

"We are constantly receiving reports from users of Power Chords who
can't believe how quickly and easily they can create music on their
computer," said Eric Bell, President of Howling Dog Systems.

Howling Dog Systems is a relatively new company devoted to the
production of top quality music software in the Windows
environment.

Advanced Gravis designs, manufacturers and markets high-quality
entertainment devices for personal computers, including joysticks,
PC GamePads, MouseSticks, and the new UltraSound, a 16 bit, 32
voice sound card for the IBM PC
