Introduction
Welcome to the exciting world of Advanced WavEffects synthesis!
®
You are now the owner of a Creative Sound Blaster
AWE64 Gold, a
16-bit audio card, which comes with the state-of-the-art Creative
WaveSynth/WG software.
Your Sound Blaster AWE64 Gold audio card allows you to achieve
realistic and three-dimensional (3D) acoustic reproduction through a
wide range of digitized sound samples and Creative 3D Stereo
Enhancement technology.
Fully Sound Blaster compatible, your AWE64 Gold audio card
supports the following features:
❑ Plug and Play ISA Specification version 1.0a complianc e
❑ Major MIDI standards such as General MIDI, Roland GS and
MT-32
❑ Compression algorithms such as A-law, Mu-law, CTADPCM,
and IMA-ADPCM
❑ Full duplex operation for simultaneous audio recordin g and
playback
Creative WaveSynth/WG employs the latest technologies for sound
creation and playback in persona l computer softwa re: sample -base d
wavetable synthesis (WaveSynth) and ph ysical model-based
waveguide (WG) synthesis.
With your AWE64 Gold audio card installed in an Intel Pentium 90
MHz (or higher) computer, the sample - based waveta ble synthesizer
allows you to play high quality music and sound effects via software
(instead of hardware) in any Windows-based multimedia applicatio n.
It also has a physical model-based waveguide synthesizer which uses
®
Sondius
Sound Synthesis technology to enable you to play
waveguide sounds polyphonically and multi-timbrally. In other
words, you can play m any notes and different instruments or sound
effects at the same time. WaveSynth/WG is also a General MIDI
synthesizer that acts like a multi-channel mixer with high quality
reverb.
vii
If you do not want to use WaveSynth/WG, you can disable it through
the WaveSynth/WG Control Panel. Then, your MIDI and audio t asks
will be handed back to the ap propriate hardware in your computer.
The combination of these features, along with our award-winning
EMU8000 hardware wavetable synthesizer, will allow you to enjoy
hours of fun listening to and creating music on your PC.
Read this simple Getting Started manual to find out how to install and
begin making the most of your ne w audio card.

In order to use your AWE64 Plug and Play using
DOS/Windows 3.x, you must ins tall the Creative
Configuration Manager first. This is located on the Creative

3-2 Installing Software in DOS/ Windows 3.1x
Optimizing Memory Usage
If you choos e to install the l ow-level DOS device dr ivers under custom
installat ion (see “Th e CONFIG.SYS File Settings” on p age B-7) , your
system will load them into memory during sy stem startup.
However, if you do not need these drivers (for example, you are
running only Windows applications or playing DOS games), you ca n
bypass load ing these drivers. Otherwise, we recommend t hat you l oad
them into high memory (for example, using memory managers).
Using Memory Managers
You can use one of the following memory managers:
❑ If you are using Microsoft DOS 6.x, run MEMMAKER.
(For details, refe r to your DOS 6.x documentation.)
❑ If you have a memory manager such as QEMM or 386MAX,
refer to their respective documentation for instructions.
Bypassing the Loading of the Low-Level Drivers
You can bypass loading the low-level device drivers by using one of
the these methods:
❑ DOS 6.x’s multiple boot sessions
With this feature, several sessions can be made available for
selection during bootup. One session can contain settings that
load the drivers int o memory. If you do not wa nt to lo ad these
drivers, you c an s elect another session that allows you to boot
up the systemwithout them.
(Refer to y our DOS 6.x do cumen tatio n fo r ins tructi ons on how
to create the multiple boot sessions.)
❑ Bypass the loading of the low-level device drivers
1. During syste m startup, press and ho ld down the <ALT> key
when the message “Start ing MS -DOS .. .” appears.
2. Release the key only when you see the DOS prompt.
