Huh? I rate Creative Music Synth as being the best soundcard-MIDI-
synth, not the best audio or musical device. The best audio equipments
are the authentic real instruments [violins, pianos, flutes, harps,
harmoniums, etc.].

I'd actually love to listen to real traditional instruments recorded
on the variable-density optical audio tracks -- consisting of film
negative -- resembling those of old B&W films.

I am against variable-area recording and magnetic recording. I really
like the optical variable-density, though.

I like using variable-density analog B&W monoaural negative [no
positive and no "reversal"; just the negatives] film optical tracks
for audio. The audio characteristics of the film make my mouth-water.
Yes, for some wierd reason, the film's audio makes me hungry.

Audio signal, in the form of light changing its intensity in an
analogous manner to the sound, is shined onto a negative film. The
film is developed and playback is accomplished by shining light of a
constant intensity onto the developed film. As the light goes through
the film, the patterns on the film will change the intensity of the
light that is received by a photoelectric cell. The change in light
intensity results in a changing electric current which is sent into an
amplifier and then to a loudspeaker.

"The Tri Ergon Process uses a technology known as variable density,
which differed from a later process known as variable area. The Tri
Ergon process had a pattented flywheel mechanism on a sprocket which
prevented variations in film speed. This flywheel helped prevent
distortion of the audio. Tri Ergon relied on the use of a photo-
electric cell to transduce mechanicalsound vibrations into electrical
waveforms and then convert the electrical waveforms into light waves.
These light waves could then be optically recorded onto the edge of
the film through a photographic process. Another photo-electric cell
could then be used to tranduce the waveform on the film into an
electrical waveform during projection. This waveform could then be
amplified and played to the audience in the Theater. The Fox Film
Corporation acquired the rights to the Tri Ergon technology in 1927."
