Hi:
Creative Music Synth -- my favorite *soundcard*-based MIDI synth-- is
the chip-based, hardware, digital FM synth present on the SoundBlaster
16 ISA card. Creative Music Synth usually has and I/O address of 220
-- hence, Creative Music Synth [220]. However, I have seen Creative
Music Synth set at 240 on some PCs. Creative Music Synth does not --
to any extent -- playback samples from memory. It freshly generates
its tones. It is physically built to generates its tones from scratch
without stealing any energy from the PC's main CPU. As such, Creative
Music Synth does not have or need any moving parts -- no discs, no
fans, etc.
Notes on out-of-phase stereo signals in Creative Music Synth:
1. I try playing Creative Music Synth, through my so called 'karaoke
voice canceller' -- which inverts the phase of one stereo channel
[right or left] and then combines it the other channel -- which
results in anything identical in both the left and right channels
being removed. I get a mono of what was different in the left and
right channels. When I play the Creative Music Synth audio through the
voice-canceller, it sounds more treble, sharper, brighter, warmer, and
crisper [qualities that I like] than when I don't use the voice
canceller. The waveforms with sawtooth-wave characteristics are phased
differently in the L and R channels, while those with sine-wave
characteristics are phased identically in the L and R channels.
2. The voice-cancellor remove whats phased similarly in L and R while
preserving what phased differently in the L and R channels. Sawtooth
waves tend to give a much brighter and warmer feel than sine waves do.
If anyone has a valid email address, I can email him/her two WMA audio
files from the MIDI audio of Creative Music Synth. File A is converted
to mono without inverting the phase of either channel. File B is
converted to mono after inverting the phase of the left channel. IOW,
file A is not "voice-cancelled", while file B is. After listening to
them, you certainly will notice the difference I describe.
3. The signals that are phased similarly in L and R are removed, while
signals phased differently are not removed. I am sure -- though I
could be wrong -- that Creative Labs deliberately made these phase
differences in the stereo Creative-Music-Synth. The sounds that are
phased similarly in L and R sound like sine-waves [such as a "whine"
or "hum"] while the tones that are phased differently in L and R sound
like sawtooth waves [such as a "buzz" or "fiz"]. AFAIK, thats just how
the company designed the synth.
Due to the above, my MIDI synth dream would be a mono, 64-bit-
resolution, 2.88-Ghz-sample-rate, 40,000-voice, 4,000-operators-per-
voice, 10,000-channeled**, version of Creative Music Synth based on
the signals that were phased differently in the original Creative
Music Synth. Creative Music Synth is a stereo FM synth who left and
right signals are phased differently, this is why I get a different
sound when I play it through voice-canceller. The signals of Creative
Music Synth that have the same phase for both L and R have a more
cheesy sine-wave quality which I don't care for. The signals in
Creative Music Synth that are phased differently in L and R tend to
resemble a fresher sawtooth-wave quality which I like. That is why I
want my version of Creative Music Synth to be based on the sounds that
were phased differently in the original Creative Music Synth. I want
my version to be monoaural because I want all speakers to give out the
same signal.
