Creative AWE64 Manual De Usuario

For the past few years, hardware wavetable synthesis has been the high-end 
alternative to FM synthesis for audio reproduction in personal computers.  
With ever-increasing CPU power and Intel’s new multimedia-extended 
instructions, software wavetable synthesis is now feasible and can be 
powerful.  This is why we have introduced our software wavetable 
synthesizer, Creative WaveSynth/WG.  Since the technology is relatively 
new, it currently has some limitations.

Due to these limitations, it is necessary to have two modes of operations for 
Creative’s sound system — full-duplex and half-duplex modes.  Each mode 
caters to different needs but has some constraints (which are explained in this 
leaflet).  Thus, you should select the mode that suits your needs.

The following constraints apply in both full-duplex and half-duplex modes:

❑ You cannot record a WaveSynth/WG MIDI playback because 

currently, the Sound Blaster hardware and driver do not support this.

❑ While WaveSynth/WG is playing a MIDI file, you cannot enable 

Creative Mixer’s LED display.  And vice versa.

Some of the constraints explained in this leaflet may not apply to your 
audio card.  For details, refer to the Readme file in you audio package.

When you select this mode, you can play and record audio data concurrently.  
But there are some constraints in this mode:

❑ If you want to play back and record concurrently, you can only do so 

using uncompressed wave files, that is, Pulse Code Modulation 
(PCM) data.

❑ While WaveSynth/WG is playing a MIDI file, you cannot do a wave 

(including DirectSound) playback at the same time.

❑ You cannot add reverb to a wave (including DirectSound) playback.

❑ Since WaveSynth/WG outputs sounds at 22 kHz, if you are recording 

a wave file at any other sampling rate, WaveSynth/WG cannot play a 
MIDI file because the sampling rates for both playback and recording 
must be the same.
