awe64 non gold can be ok? have you ever tested in dos?
The "64" in the AWE64 does not refer to any hardware improvement over the SB AWE32. An AWE64 card still has exactly the same EMU8000 synthesizer as the AWE32 with technically 32 voices, some of them reserved for system functionality. It also has the same architecture for digital sound and the MIDI port for external devices as the SB16, just as the AWE32 does, too. So in DOS, an AWE64 is just the same as an SB (AWE)32.
The feature distinction between the AWE32 and AWE64 is that the AWE64 is shipped with a software MIDI synthesizer using a physical modelling approach called "WaveGuide", that can provide 32 software voices in addition to the 32 hardware voices. The output of the software synthesizer and the digital sound played back by (other) MIDI applications are mixed by Microsoft's generic kernel mode audio streaming system provided with Windows 98 and newer.
From the hardware perspective, a AWE64 is a higher integrated (and thus lower cost) variant of the SB AWE32. It misses some features of the better AWE32 models like the waveblaster header, or the expandability of the sample RAM using standard 30-pin SIMMs. If you look at the AWE64 as a late budget edition of the AWE32, and are fine with the cost-cutting methods Creative applied, there is nothing wrong with it.
As a final note, there is no technical limitation preventing to use the 32-voice software synthesizer with an SB16 card that does not contain a EMU8000-based hardware wavetable synthesizer. In the end, Creative did just that, and sold a relabelled SB16 vibra variant bundled with the WaveGuide synthesizer as SB16 WavEffects.
