<b>Miscellaneous</b> - Fake editors for musical co-processor.

5m Something about not very musical co-processor, or anyone on 
the bear arrived. (C) 1997 E. Nesterenko (Jam 
)________________________________ Nobody knows exactly, 
skolkovekov ago appeared vidiskusstva such as music, but 
odnomozhno say is true - it was the IMAGE-retatel genial 
personality, completely. Perhaps it was ka-Khoi-something 
woolly pre-historic human ancestor, confident that rhythmic 
post-repulsion clumsy paws on the mammoth-stretched skin, 
coupled szaunyvnymi нечленораздельнымивозгласами and violent 
shocks around the campfire will provide successful

hunting, or good weather, or
improve reproduction of the tribe.
Could well be that no
one he had previously thought of as
was their multiple, and
on different continents,
isolated from each other excessively spilled waters of the 
Great Ocean, and is prohibitively rise mountain ranges, but not 
that we are interested ... 

   And now we are interested in the consequences of a very old 
event. So, what do we have to today? Millions of tons

plastics in the form of squalid plates, hundreds of millions of 
sparkling rainbow CD

drives billions of miles
magnetic film, thousands of firms
Recording tens of thousands of music education, opera houses, 
music stores, music teleperedach.Ya Not to mention the number 
of people who create, perform music and a huge army of 
listeners - To one degree or another, but all

We are entering into it, getting in
fantastic sum of
audio equipment and various Sound (on the plates before
magneto-optical disks). Music became part of neotemlimoy 
scientific, technical and production process ("we build the 
song and help us live ...") Of course, the creators of the 
eighth wonder of the world - the computer, it

knew, therefore, more or less diligently supplied
their offspring music. I shall not dwell on Khrenovoe sound 
pisyushnyh music boards and allegedly superior sound Amiga 
(Personally have not heard, I will not lie ...), but I want to 
stay on native Spectrum co-processor. Of course, he can not 
compete with the Amiga and even SOUNDBLASTER'om, but in any 
case, much steeper than PC-SPEAKER'a. Here lately the fashion

invent all there COVOX'y,
SOUNDRIV'y, GENERAL SOUND'y and
even some semi-mythical not
then ULTRAVOX'y, not ULTRVOX'y.
All this, of course, is good. I understand the apparatchiks - 
they, too, to sit idly by do not want need a free flight of the 
creative thoughts and feelings. However, there is

here's one big but, but (more
one!) about it, we'll talk some other time, but for now let me 
go back to the good old AY. Admittedly, each of you

(If you will ever
dealt with the Spectrum) panted a certain amount of
man-hours (or computer-man, as someone like that)
for one (or two) of music editors. If you say that this is 
true, then I would not believe. I am not

exception, and one (oh no,
It was far from perfect)
Day decided to immortalize his name
in music history. Steep Mouzon
should be written (do not think
something wrong ...) in a steep editor, I thought, downloading 
PROTRACKER in its PENTAGON ... 

   When the eyes began to see double, and in his ears and even 
troitsya four, I realized that to become a composer is not easy 
... Then I decided to become malignant

plagiarist and a bit of breath, has launched a CD FAITH NO
MORE specimen 1992. But when
poured from the speakers "Midnight
Cowboy ", I suddenly in surprise
discovered that I could not pick up
tone in which this song
performed. Hmm, the guitar is
I managed to ... I tried
several disks, but the result was the same - PROTRACKER
shamelessly out of tune. I tried a couple of editors, but
picture has not changed. Buggy
computer, I decided. There was another version - the 
capitalists specifically so cleverly set up their Tools for CD 
recording that plagiatchikam leaving no chance. But this 
version was very, very doubtful, so I decided to postpone until 
the musical exercises and find the bear, stepping on

"Ear" native coprocessor. But in
resulting investigation revealed
that that bear is not having the coprocessor on the ear, and 
the creators "Music" editors, and, apparently, not only in the 
ear ... Some time ago I caught the eye in the article AMADEUS'a

FLASH TIME magazine about
the same problem, but on this brilliant article, we'll talk 
later, but for now let's try clarify the causes of false 
editors. 

   So, with regard to the reasons
the reasons must be sought in all
the same, already nabivshey abhorrent to nausea nauseam,
compatibility. This time proved to be incompatible clock 
frequency - in branded machines it according to some, still not 
3.5 MHz ... Some sources claim that the harmful frequency is 
3,45 MHz, others - 3.577. Check out this rather difficult

however, it can be argued precisely: the
have its own frequency,
samostiynaya and differs from
capitalist (nehay girshe,
Abi inshe!).

   Well, it's good, but that
also follows from this? And should something
that the frequency of hours of music. coprocessor is obtained 
by dividing clock frequency by two. Further,

I think you all clear if
you have at least three and a minus for
arithmetic. For those who are on an armored train, explain: 3,5 
/ 2 = 1.75, and if the 3.45 / 2 = 1.725. Now

try to calculate the constant
coprocessor register for tone, for example the notes C-fourth 
octave: 

 K = 1750000/16/261.64
 K = 418.0 (this is on our comp)

 K = 1725000/16/261.64
 K = 412.0 (which is on the company)


   Where K - is a 12-bit
constant for the tone registers
coprocessor, 1750000 and 1725000
- Split in half clock
frequency 261.64 - frequency notes
P-fourth octave, and about 16, we
Again, talk later ...

   One would think that's wrong with that?
Is it not possible to count
constants for "our" computers?
It is certainly possible and even necessary!
But the trouble is that none of the
creators of numerous music editors do not bother
to do so. So I want to
pages of the magazine to apply it to them: the people, think 
again! Repent of their sins, and URGENT Released a new, reworked

Version of their program, because Burning YOU IN HELL FOREVER! 
;-) 

   ... And now the news articles
and the mysterious number 16. If
read that same article in the journal "FLASH TIME # 1", then 
there a formula to calculate the constants is exactly the same 
as above, but at 16 there is 12. Yes, AMADEUS 'FLASH first

talking about the problem of sound
editors, it's great for them
plus ... But, comrades! If you are
criticize other people's constant, so
Let us precise the! Why
your also wrong? But
you simple example: Take
from you as this table
frequency value of music for music first octave - 32.70. Right 
now substitute in its formula:


 K = 1750000/12/32.70
 R = 4459.73


   Well, like, here? If not,
Then read on. It's no secret that the ill-fated
constant is 12-bit.
Now let's calculate the maximum number that can be
obtained from 12-bit:


  1) Low byte = 255

  2) 0,1,2, and 3 bits of older

     bytes = 15 * 256 = 3840

  3) 3840 +255 = 4095!


   So in-the-by, maximum
number, obtained from 12 bits
is 4095, and now imagine
What happens if submit coprocessor number 4459.73 (rounded to
until 4460). In binary form:


      % 01101100 - Junior

      % 00010001 - Senior


   A coprocessor is a taking only
4-bit high byte! So he
take 108 (Jr.) + 1 * 256
(High) = 364! Well as you need it?
So the next time I advise AMADEUS'u seriously consider
before publishing misleading articles.

   And while I am waiting for new, RIGHT music editors
for the Spectrum ...


   And another thing: why in all-all
muses. Editors at the same time
You can only work in one
octave? It's so inconvenient!
Of course, I understand that the keyboard is not rubber, but 
you can for example, involve a number of digital keys and a 
number under it to simultaneously "work" though least two 
octaves. Here's a reason for thinking ... For symmetry, let

leave, our brush with you!
