mmm, very nice :) yes - if i had the money i'd be getting a good TFT
too... the CRT proves to be very damaging when i'm vulnerable to
seizures - i've had to work in bursts and sleep all day at the moment.
thats been an issue for me as well - my secondary career is as a graphic
designer, so i have to be very careful to get accurate -as in Pantone
accurate - color representation. my laptop simply won't do it- it
overemphasises color so everything gets greyed out. i'm no longer able
to work with it, which makes work difficult at the moment to say the least.

i can give you some further references to this - perhaps it deserves a
thread of its own. i'll try and dig up the information i went looking
for when i first developed seizures.
i had my 8th cranial nerve completely destroyed by a medication. this is
the nerve which runs from the forehead to the cochlea and ultimately
into the temporal lobes. the temporal lobes are basically where all our
work is done as musicians. i had a disturbing session with an
audiologist where he used a tuning fork test, and i could hear resonance
on both cheekbones, but when he placed it on my forehead i heard nothing
at all. i then did the standard sine tone stuff and it was discovered
that i had lost hearing in a particular range. its quite possible that
this happened due to the damage to this particular nerve. i'd give
information on the particular medication but i'll leave that for now.
suffice to say its an oldfashioned, unstudied and potentially dangerous
medication for all but a few, for whom it works miracles.
i believe this was the main page i found:
as you will read, the right temporal lobe is the seat of musical and
artistic comprehension and creativity. i have perfect pitch - a function
of the right temporal lobe. part of the damage i experienced uncovered
dyslexia and worsened my dyspraxia - operations of the left side of the
brain, including verbal, physical skills and memory problems. my main
difficulties are dyslexia and seizures - often which will begin with
dyslexic episodes, which suggests my problems are on the left side of
the brain. it should be noted that not everyone has all the symptoms, by

indeed. i should investigate this - i've been on the lookout for good
mixing / mastering software.
your work sounds quite beautiful in its mastery of these areas. as you
say (in citing the band) not everyone manages to achieve this, in fact i
think its a rare few.
one of the things that has fascinated me for a long time was the
extremely wide stereo and depth of sound in French pop music.

hmm, sounds like someone's mentioned that in another post, possibly ? ;)

heh, well i think it is... it is, somewhat like Eminem, exorcism of my
own personal demons. i'm going to take the majority of this off-list, as
it gets too personal, but lets just say i've attempted - and succeeded
in the most part - to create freaky effects such as tube trains
screeching to a halt in front of the listener, with a sudden jump cut to
totally irrelevant spoken voice, and one particular psychological
'masterpiece' for myself, 'thioridazine dream' - a walk around in the
mind of someone gradually cracking up. it was designed -rather cruelly,
but the nature of the piece demanded it - to leave the audience drained,
and it worked.
as far as any freaky psychoacoustic effects, i'd highly reccomend
listening to sound effects in psychological drama movies. good ones that
is - not the cheap dramatically emotional effect. the first half hour of
Saving Private Ryan, and its portrayal of shellshock and a very graphic
visual and aural experience in the reality of war, is a prime example. i
wish to show human reality - to exorcise my own demons, but also in
Saving Private Ryan, the sound work educated an audience that would
otherwise be oblivious to the graphic realities of war.
