   Today there will be about creating music with digitized 
sound with Program Instrument 3.01. Digitization of sound sound 
more realistic than usual sound, such as in SoundTracker'e. 
Still, the digitized sound has some disadvantages that narrow 
its Use:

1. While playing a melody
virtually impossible to work
other procedures. In most
cases, the only procedure
running while playing, can only be a poll the keyboard.
2. Sound coming from the port AY3-8910/12, not very clean. More 
clean sound is obtained by means of special peripheral devices 
(Covox, etc.). But while these devices are not common, and they 
have not written software.



   Program Instrument 3.01 -
a tool for creating tracks with digitized sound.
It can not fully be called
music editor, as
its editorial features
very scarce. But there are some options makes it easy
Labor convert tunes
famous music editor Asc Sound Master (ASM).



   Brief characteristics of the prog
FRAMEWORK Instrument 3.01:


 - Length of track - 2048 notes
that is 32 patterns editor
ASM, with 64 notes in each pattern;
 - 7 downloadable tools
(Samples);
 - Built-in converter ringtones
with ASM;
 - The possibility of transposition of each of the seven 
samples, ie raise or lower the sample to few semitones;

 - A convenient system load / save as ring tones and samples;
 - Instrument has a wide selection of control: Keyboard S,
X, O, P, SPACE, SINCLAIR 'KEMPSTON JOYSTICKS, KEMPSTOM MOUSE;
 - A convenient window user interface and
piktogrammnye menus provide
comfort in working with the program.


   The list of advantages Instrument'a not end there, but
they are not considered separately
be. We now turn from theory
to practice.



       Creating a composition.



   Necessary equipment and
Software:

 - ZX-SPECTRUM 128K with a floppy drive, a musical co-processor
AY-3-8910/12.
 - INSTRUMENT 3.01 with a set of
samples to him.
 - Moose. Editor ASM 1.11 ASM-disk format for downloading 
ringtones. 



   The following statement is dedicated to those who have little
familiar with the music editor
ASM.



   Manufacturing tunes in ASM.



   The first thing you must download ASM. Next, go to 
ASM-editor of the samples labeled option SM. XX (not to be 
confused ASM-samples from INS-samples!) need to create 7 
arbitrary samples with numbers

1 to 7. Samples should not be
identical, their structure depends on your taste. In the 
future, if you convert, ASM-samples are replaced by 
INS-samples. You can also (but not necessarily) enter into an 
editor ornament (option IM. XX), to make some ornaments. They 
are required only for convenience in creating compositions 
ASM'e and no plays no essential role. 

   After manufacturing of samples and
ornaments they need to write to
ASM-disk format as the melody, but
not as separate samples. This
file can be used in the future when you write the following
compositions.

   The next stage - is to write melodies ASM'e. Details
dwell on this, I will not. Let me just say a few remarks and 
restrictions:  1. The range of compositions have

be no more than 4 octaves. This is due to the peculiarities 
Instrument'a. The most common period - is LARGE, SMALL, 1-ST and

2-ND octave.
 2. You can not use the command
PORT, GLIS, SPEED, etc. They will ignororovatsya converter
Instrument'a.
 3. Pause (PSE) maintains its
action and Instrument'e.
 4. It is advisable to use
only 7 made samples and any number of ornaments.


   After making tracks
it should be written to disk ASMformata for the possibility of 
further debugging. Then, entering the ASMCOMPILER, compile the 
resulting melody and record it on TR-DOS disk. The process of 
creating completed.




          Convert.



   After a successful write to disk
compiled file, it is necessary
Download Instrument 3.01. Entering
a menu of disk operations (icon in the form of a floppy disk), 
choose option Import ASM block. Using it, download the file 
created with composition. Table appears

(Conversion table).

   Top of the table is
a series of numbers from 0 to 31. They are samples ASM'a. Near
Each of the numbers, separated by a colon
is a number from 0 to 7, a dash,
or nothing. The figure indicates the number of INS-sample. 
Denoted by a dash ASM-samples, which did not enough "sample 
Instrument'a. If you were writing a composition in ASM

on the above described method, the
dashes should not be. Bridging
arrow on the number of INS-sample and
pressing FIRE, it can be changed.
INS-sample number 0 is not involved.

   In the lower third of the screen is a list of octaves ASM'a. 
Similarly, the table of samples, here through the colon are an 
octave Instrument'a. Octave number 0

not involved. A dash can
standing, if your song goes beyond the four octaves.
A dash also appears when
track is not located in the LARGE, SMALL, 1-ST-ND and 2 octaves
but its range does not exceed four octaves. In this case,
simply point the arrow on the dash and click to set FIRE
the desired octave. If your
composition is more than 4
octaves, it is possible, pooperirovav
arrow and click FIRE to assign more than one ASM-one 
octave-native INS-ovsky. Similarly, you can do with samples,

ie multiple ASM-sample assign INS-ovsky. This is done by 
pointing the arrow on the dash and pressing FIRE.


   Right of the table is a plate of octaves channels. It
exchanging channels AY
if you wish.

   After completing the
table and out of it with the options OK, need to pick up on the 
rumor INS-samples, downloading and running the melody icon in 
the form of the dynamic head. On distributive drives there are 
a large number of samples. Their diversity should be enough for 
your tunes. Download by pointing the arrow on the screen area 
to the right of numbers of samples (top left

quarter of the screen) and then
pressing FIRE. Appears directory
samples with their length.
On each instrument reserved for 16384 bytes. But the second and
7th samples are placed in areas of the fourth and fifth 
samples, respectively. It turns out that the pair samples (4 
and 6, 5 and 7) goes to only 16384 bytes. Because of this

should closely monitor the memory usage. Most
bulky instruments should be
placed first. For debugging
you have no time to enter the
CONVERSION TABLE, and will therefore be wise to keep a table on 
the disk (Disk menu operations, the option "SAVE CONV. TABLE". 
To access CONV. TABLE, need to repeat the "IMPORT

ASM BLOCK ").

   And finally, when the instruments are chosen, you
can enjoy the written
product. Now we just need to write the track on the disc
option "SAVE TUNE".


   If you did not understand data
Naya instructions (my fault)

or you want to hear anything

about music ZX-SPECTRUM, then write

to the journal "ZX-FORMAT"

in the name of Andrei Litvinov (LAV'a).


Good luck in your music.
