¯Digital Music Administration.~ 15 Hollycombe Close, Liphook, Hants. GU30
7HR
England.
Every fortnight in this section we will be concentrating on the audio side
of computing. That is, music-modules, sampling software, sampling hardware,
module players, etc. Also techniques that can be employed when writing your
own sound modules.

Trackers. What are they?
------------------------
~
A 'tracker' (such as SoundTracker, NoiseTracker, Protracker), is a utility
whereby you may create your own songs on your computer. You build up a set
of instruments and then use those instruments to create your tune.
The good point is, even if you only have the most basic knowledge of music
writing, you can still create a tune fairly quickly. You certainly don't
have to know how to read or write musical notes. In fact, even if you *do*
know how to read and write music, it won't be of any use on most trackers.
This is because you enter notes into the program as a letter, such as 'A'
or 'B' or 'C#' etc, rather than by actual musical notes, (crotchets, etc).
¯
Where do I enter the notes?
---------------------------
~
The notes are entered in the form of a list. To explain, below is a
representation of the part of the tracker where you enter your notes:
¯
----------------------------------------
|00|E-201000|---00000|---00F05|---00000|
|01|---00000|---00000|---00000|C-203C20|
|02|---00000|B-102000|---00000|---00000|
|03|---00000|---00000|---00000|---00000|
~
I'll explain each part of this display: The first column (the one with¯00
01 02~and¯03~in), is the position number in the list. The next column has
¯E-2~and also three more rows of¯---~ This is the column where you enter the
notes that you want.¯E~for note E (surprisingly), and¯2~for octave 2.
There's only three octaves to choose from. The¯---~mean that no note is to
be played.
In the next column, each row has five¯0's~ in it, except position¯00~, just
after the¯E-2,~ there is¯01.~ This¯01~means that the note¯E-2~is to played
with instrument number¯1.~So, the first two 0's in the row of five 0's mean
which instrument you want to play. The last three 0's in the row of five
0's are for commands, which I'll explain a little later.
You may notice that the next column looks similar to the last block of
columns. This is true and in fact you may treat it in the same way. You may
enter notes in this column too. This is the second channel. The computer
has four sound channels through which it can play samples. So, the other
two blocks after this one are also treated in the same way, you may enter
notes in them. These are channels 3 and 4 respectively.
If you look in channel three at position 00, you will notice that there is
no note there but in the area used for commands there is an ¯F05~. This is
a command that alters the tempo (speed) of the song. The F represents a
tempo command and the 05 is simply the speed at which you want the song to
go, in this case 5.
Also, if you look in channel four at position 01, you will see that there
is a C20 command after the C-2 note. The letter C denotes a volume command,
and the value 20 repesents at what volume you'd like the instrument to play
at.
There's many different commands you can place after notes and some that
don't need notes in front of them to be activated, including three
portamento commands, vibrato, arpeggio and volume slides.
One last thing for this issue, you will notice that my representation
diagram above shows the position column going from 00 to 03 but no further,
well actually on the real trackers the position goes from 00 up to 63, but
as you'll see later on, you can change this.
That's all for this issue. Next issue, more about the commands.

MODULES
-------
~
This is to be a regular feature of the Digital Music section. So we want
your input. Please send us any 'tracker' modules that you have written and
if they are good enough, you should see them in this section of the
magazine. The best one each issue will be used in the menu-selection music
of digital disk, and the author's name will be shown here in this section.
Please send your modules to the address at the top of the page and always
remember to quote your user id in any correspondence to us.
¯
NOTE: Sorry people, but there simply wasn't enough space on this issue's
disk for me to include the modules from the others. I naturally will kill
myself immediately...........
....
....BANG!
That's better! I hope you forgive me now.. I'll tell you what-I'll try and
get them on the next disk... If you can't wait that long, write to me (or
email me) and I'll send them to you... - 68K [hs1st1].
