Proudly Presents
DIGI COMPOSER
HISTORY
This program was originally called Noisetracker and was
created by Mahoney and Kaktus on the Amiga. Later on a belgican
guy called Dr Satan from F.A. converted the Noisetracker and
created a ST-version. But the ST-version didn't include all the
functions that the Amiga version had. Something had to be done. Il
Profesore from ISTARI created DIGI COMPOSER; a modified and
extended version of the ST Noistracker (see function details
below). Digi Composer is public domain!!!
Original Amiga version:Mahoney & Kaktus
Original ST version: Dr Satan/F.A.

DIGITAL MUSIC TECHNIQUE
Hello fans! Well.. Let's us just be modest. Bitmaster wanted me
to write something about Digi Sound. So here we go:
TO PITCH OR NOT TO PITCH THAT'S THE QUESTION
To play a sample at different pitch (to pitch it) is very much
the same as variating the frequency of any periodic wave such as
the sinus wave: the faster you "move" trough the wave the higher
the pitch becomes. This is simply done by adding a constant to a
pointer which points to the sample and looking for the end of the
sample. The adding can be done in many different ways but it
would be too boring to read if write about everyone of them so I
don't write about any of them.
Pump up the volume!
Yep a digi sound tune becomes much more amazing if you are using
volume control or VELOCITY CONTROL. This is not very hard to do:
just adress a multiplication table using the sample data as a
pointer!
Add it upp!
In the end the channels are added together and played. That's it.
This tiny text is not ment to be understood but I hope some of
you out there have understood.

LAZY USER
Look in Digi Composer HELP area if you want to get started
quickly!
REFERENCE AND EXAMPLES
Here is a list of all functions and commands that can be used in
Digi Composer. To make this program easy to use and understand,
all facts in this manual are shown with examples and notes.
PRINT THIS TEXT!!! It's much easer to work with Digi
Composer if you have this manual beside you. If you don't own a
printer, use your printer-owning pal (and let him pay for the
paper). Well, the masterminds out there can maybe learn this
manual by heart.
MARKS & NOTES are...marks and notes. BIG unbolded words (or (see
???)) means that you can look them up. The ([???]) among the
screen functions means that the function can be performed with a
key.
-------------------------------------------------------------- --
SCREEN FUNCTIONS are all the buttons that you can click to change
parameters, modes etc. Also included in the screen functions
((conception are different kinds of status frames.
KEY FUNCTIONS are all the keys that you can press to change
parameters, modes etc. Some SCREEN FUNCTIONS are also available
on some keys. A great deal of the key functions are conducted to
the EDIT FUNCTION.
COMMANDS is a way to create effects as echo, vibrato etc. You
simply type the command code on a note and the desired
(necessary) value and there you are...
MODES are made so that you only can preform certain actions in
respective modes. There are three exeptions (see L,M & H).
NORMAL MODES (play, pattern, stop): In thoose modes, you can
only lissten and stop your modul.
EDIT MODE (edit!) : In this mode, you can enter notes and
commands.
RECORD MODE (record!) : In this mode, you can enter notes in
real time while the pattern is runing. You can only record one
pattern at a time.
FIELDS appears in two form: SONGNAME and SAMPLE.
SONGNAME : If you load a module the module name should be
displayed in this field. If you have created a own module you
should enter the module name here.
SAMPLE : If you load a sample the sample name should be
displayed in this field. If you have modified a sample (whith the
SAMPLE functions) you should enter a new name here.
TIMER is a...timer. It's really nice to see how long a song is,
or?
While the timer is running:
LEFT MOUSE BUTTON : toggles the timer start/stop.
RIGHT MOUSE BUTTON : toggles the timer interval/continue.
When the timer is stopped:
RIGHT MOUSE BUTTON : zeros the timer.
-------------------------------------------------------------- --
RIGHT MOUSE BUTTON (in general): Click the up and down arrows
and hold the button to rewind.
"COLORED" FRAME : To make it clear which function that is
choosen.
"COLORED" ARROW : To mark that a function is used.
-------------------------------------------------------------- --
SCREEN FUNTIONS
-------------------------------------------------------------- --
POSITION 00 U D
Name Steps Up/Down arrows
Position is the order of the patterns in the melody.
PATTERN 00 U D
Name Steps Up/Down arrows ( [INSERT] / [CLR HOME] )
Pattern is a melody string containing 4 channels and during about
4 bars. A melody is built up of different bars.
LENGHT 00 U D
Name Steps Up/Down arrows
Length is the number of positions in the melody (added with 1).
RESTART 00 U D
Name Steps Up/Down arrows
Restart: you can set a position from which you want to restart
after reaching the melody end. (Ex. neverending refrain, start
all over again).
----------------------------------------------------------------
SAMPLE 00 U D
Name Steps Up/Down arrows ( [+] / [-] )
Sample is the "memory sample libary". You can load samples into
the memory using the LOAD SAMPLE function (see DISK). The
so called libary is your orchestra which contain samples, that
are instruments. Simply change instruments with the arrows.
FINETUNE 00 U D
Name Steps Up/Down arrows
Finetune let you tune the instument (sample).
VELOCITY 00 U D
Name Steps Up/Down arrows
Velocity controls the volyme on the instrument. Set the volyme
with the arrows. The V must be darked before this function would
make effect (see V).
LENGHT 0000 U D
Name Steps Up/Down arrows
Lenght is the lenght of the instrument. You can change the lenght
with the arrows (ex. take away noise and clicks).
REPEAT 0000 U D
Name Steps Up/Down arrows
Repeat will repeat from the number of steps that is adjusted.
REPLEN 0000 U D
Name Steps Up/Down arrows
Replen is a function which allows you to set the lenght of a
loop. (Ex. try changing replen value to make
a "good" loop).
---------------------------------------------------------------
1
Number
1: stands for channel number one (from right to left). A left click
toggles between ON/OFF (darked/lighted). This on/off is simply
volume which is turned on or off all commands and noted are
executed/played. If you "right-click" the number will disappear
and all functions , notes etc are NOT played
2
Number
2: stands for channel number two. A click toggles between
ON/OFF. See above ...
3
Number
3: stands for channel number three. A click toggles between
ON/OFF. See ab..

4: stands for channel number four. A click toggles between
ON/OFF. See ...
V
Name
The V stands for velocity. This function confirm to the command
for velocity in a module.
A
Name
The A stands for amplify. Pump up the volume!
---------------------------------------------------------------
PLAY
Name
Play starts playing from the chosen position (respective
pattern) to the very end. You choose position with the POSITION
function. Mousepointer turns yellow.
PATTERN
Name
Pattern plays a single pattern (the one choosen) or a block which
is defined with the BLOCK function. Mousepointer turns yellow.
EDIT ( [SPACE] )
Name
Edit let you create a pattern (score) with the different keys
which grasps 3 octaves (see KEYBOARD). You can change
instrument as many times you like in each channel. Mousepointer
turns blue.
RECORD
Name
Record records your bashing within the 2 octaves. The recording
is in real time and only one pattern at a time can be recorded.
Mousepointer turns blue.
TEMPO 06
Name Value
Tempo is setting the speed of the song. The standard value is: 06
(ca. 124bpm) Change value with mouse buttons: left=faster,
right=slower.
---------------------------------------------------------------
STOP ([SPACE])
Name
Stop interrupt using PLAY or PATTERN. Mousepointer turns white.
DISK OP.
Name
When clicking the DISK button a number of buttons will appear.
These buttons are different kind of disk options.
Double click on a button and DigiComposer will change
directory (you must of course check that you have inserted a new
disk).
INVERTED TEXT : Elucidate which file that is choosen from
the directory.
L SAMPLE
Name
Load sample loads a sample to the memory. Choose a destination in
memory by the SAMPLE function (clicking the arrows). (Ex. set
sample number 3, then use LOAD SAMPLE and you will for ex. have a
"stringsound" as instrument (sample) number 3).
S SAMPLE
Name
Save sample saves the instrument (sample) with the name standing
in the SAMPLE FIELD and automatic put .SPL or .AMI ,according to
what sample type is chosen,(Se prefs) as extension. If you
want to change the name of the sample click in the SAMPLE FIELD.
FREE
Name
Free displays the free space on the current disk.
L MODULE
Name
Loads a module into memory. A module is a melody,song or
whatever you would like to call it, that is a complete work.
S MODULE
Name
Save module on disk. Saves your complete work: patterns and
respective positions, used samples (even the manipulated).
Modules takes plenty of diskspace much because the samples data.
FORMAT S
Name
Format single sided. Formats a disk with 80 tracks and 9 sectors.
FORMAT D
Name
Format dubble sided. Formats a disk with 80 tracks and 9 sectors.
DIR:
Name
Directory. Showing the active drive, paths...
SAMPLER
Name
When clicking the SAMPLER button a number of buttons will appear.
These buttons are different kind of sampler options.
WINDOW OP.
Name
When clicking on this button two additional buttons would occur:
NORMAL SCOPE : This is the "normal" state. You can see the
current samples appearances.
TWIN SCOPE : This is the "loop" state. If you look at
the left part, you would see the begining - end of the sample and if
you look at the right part, you would see the end-begining of the
sample. This is a visuall way to conform a good loop.
ZEROP.FIN.
Name
This is a zeropoint-finder! When clicking on this button two
additional buttons will occur:
REPEAT :
RIGHT BUTTON: Searching for a zeropoint upwards in the
sample (from a lower to a higher address).
LEFT BUTTON: Searching for a zeropint downwards in the
sample (from a higher to a lower address).
When the zeropoint-finder have reached the end (or beginning) of
a sample you can stop clicking because it's no use! Look how
the repeat value change in the valuefield of REPEAT. You can, of
course, click the arrows to step up and down.
REPLEN
RIGHT BUTTON: Searching for a zeropoint for a loop
upwards in the sample (from a lower to a higher address).
LEFT BUTTON: Searching for a zeropint for a loop
downwards in the sample (from a higher to a lower address).
When the zeropoint-finder have reached the end (or beginning) of
a sample you can stop clicking because it's no use! Look how
the replen value change in the valuefield of REPLEN. You can, of
course, click the arrows to step up and down.
NOTE : Use zeropoint-finder in addition to the TWIN SCOPE.
TRANS
Name
When clicking on this button two additional buttons will occur:
OCTAVE UP : transpose the sample one octave up.
OCTAVE DOWN : transpose the sample one octave down.
---------------------------------------------------------------
VOLUME
Name
With this strange function you can lower the sample volume!
The thought behind this function is that it's somethimes
nessasary to syncron diffrent samples volumes (because of not
having to adjust the volumes every time you would like to use in
a new module).
Simply adjust the samples volume with the arrows which
affect VELOCITY and the press VOLUME.
ex. flutesnd: velocity 40 (hex), which you adjust to:
flutesnd: velocity 20 (hex), click volume, adjust to:
flutesnd: velocity 40 (hex), which now should have the 20
(hex) volume.
FADE
Name
When clicking on this button two additional buttons will occur:
FADE IN : doesn't you have any tiny ide‚ what could happend?
FADE OUT : if you have, you must be a experienced hacker!
COPY
Name
If you would like to take a copy of the current sample, which
you're going to manipulate. Enter destination.
REVERSE
Name
Again a function that's incredible hard to say anything about,
but I can say: Hi! (better now?).
PREFS
Name
When you click on this button a preference menu will occur.
There are three menus with different kind of settings, which
after fitting your wishes, should be saved. DigiComposer would
from now on load a DIGICOMP.INF file, when you start the program.
Change default settings by clicking or editing.
PREFS : A:\ _ _ _ _ _ (Drive and path/s were DC will save the
DIGICOMP.INF file.
NOTE:The DIGICOMP.INF file must be located in the very same
directory as DC or it won't be loaded!
MODULES : A:\ _ _ _ _ _ (Drive and path/s were DC will look for
modules.
SAMPLES : A:\ _ _ _ _ _ (Drive and path/s were DC will look for
samples.
PALETT : MONO (MONO or COLOUR (see [ALTERNATE])
DEFAULT MODE : MEDIUM (Low, medium or high (see [L],[M] & [H]))
OVERSCAN : OFF (Ovescan on/off (see [O]))
STE MODE : OFF (STE mode ON/OFF)
STEREO MODE : ON ("Amiga-stereo" mode (not panorerad stereo))
VELOCITY AS : HEX (Are you a programmer or not?)
see H/D!
ST. OUTPUT : YM2149/PROSOUND (Stereo output)

TRANS 00
Name Value
This function is quite useless, but it's fun. Change value with
mouse buttons: left=higher, right=lower.
---------------------------------------------------------------
CLEAR
Name
When clicking the SAMPLER button a number of buttons will appear.
These buttons are three diffrent ways to destroy your work!
CLR ALL
Name
Clear all clears everything in memory. Patterns and samples, all
will be cleared. This is a sort of "new" function. Remember to
save your work before using this function (see DISK).
CLR PATS
Name
Clear Patterns clears all the patterns in memory, but the
"sample libary" will still be there. This is a sort of "I'm not
satisfied" function. Remember to save your work just in case you
regret (see DISK).
CLR INST
Name
Clear all samples in memory. Your whole "sample libary" will be
lost. Remeber to save your work just in case you regret (see
DISK) (You maybe had edited the samples with the SAMPLER).
HELP ( [HELP] )
Name
HELP! This is a integrated helptext which contain a so called
"get started" and short references.
ABOUT
Name
Well, this one is really nice! Don't you agree. Painting the
logos was a piece of cake compared to writing this manual!
QUANT 01
Name Value
This function defines how many lines you wish to go down, when
you work in EDIT MODE, after you have placed a note or a command.
Change value with mouse buttons: left=bigger steps, right=smaller
steps.
COPY 01
Name Value
The nummer of copies you wish to make of a defiend block (one or
four channel (see FUNCTION KEYS)). Change value with mouse
buttons: left=more, right=less steps.
---------------------------------------------------------------
H/D
Name
Hexadecimal/Decimal. Choose which number base you want to display
VELOCITY with.
NOTE: The standard is hexadecimal however there are some strange
modules where the velocity is decimal. This feature was
built in to support those too. It is adviceable to use
Hexadecimal!
E
Name
Extended. SixTeen Extended (STE). If you own that kind of Atari,
be happy. It really sounds C(ruel!!!).
O ( [.] )
Name
Overscan. Why bother about the low border? This function was
created to make it easier to edit (see L).
OO ( [UNDO] )
Symbol
Stereosymbol. The stereo can be heard on normal STs if you
connect a sampler with output you can hear one channel through
the cartridge and one through the monitor. See in preferences
which cartridges DC supports. Or if you own... (shut up!)
Il Profesore's NOTE: After the DC had been packed I found that I
had written MT 16 instead of MV 16. Ehhmmm... But I was too lazy
to pack it one more time.
L ( [(] )
Name
Low. This is the low replay frequency (see DIGI COMPOSER
FEATURES). The Overscan function only works in this mode.
M ( [)] )
Name
Medium. This is the medium replay frequency. It starts sounding a
little bit better now!
H ( [/] )
Name
High. This is the high replay frequency. It sounds marvellous!!!
(I don't want to to think about how much processor time there is
left. Even the graphics ("peak" & osci) are removed just to push
the replay frequency to a maximum).

E6 - Patternloop EE - PatternDelay
E7 - Tremolo Control EF - Funk Repeat
Cmd 0. Arpeggio (Range:#0-#F/#0-#F)
Usage: #0 + 1st halfnote add
+ 2nd halfnote add
Arpeggio is used to simulate chords. this is done by rapidly
changing the pitch between 3(or 2) different notes. It sounds
very noisy and grainy on most samples, but OK om monotone ones.
Example: C-300047 C-mayor chord:
(C+E+g or C+4+7 halfnotes)
C-300037 C-minor chord:
(C+D#+G or C+3+7 halfnotes)
Cmd 1. Portamento up (Speed:#00-#FF)
Usage: #2 + portamento speed
Portamento up will simply slide the sample pitch up. You can NOT
slide higher than B-3! (Period 113)
Example: C-300103 1 is the command, 3 ist the portamentospeed
NOTE: The portamento will be called as many times as the
speed of the song. this means that you'll sometims have
trouble sliding accurately. If you change the speed
without changing the sliderates, it will sound bad...
Cmd 2. Portamento down (Speed;#00-FF)
Usage; #2 + portamento speed
Just command 1 except that this one slides the pitch down
instead. (Adds to the period). You can NOT slide lower than C-1!
(Period 856)
Example: C-300203 2 is the command, 3 is the portamentospeed.
Cmd 3. Tone-Portamento (Speed:#00-FF)
Usage: Dest-note +#3+slidespeed
This command will automatically slide from the old note to the
new one. you don't have to worry about which direction to slide,
you need only to set the slide speed. To keep on sliding just
select the command #3 + 00
Example: A-200000 First play a note
C-300305 C-3 ist the note to slide to,
3 is the command and 5 the speed
Cmd 4. Vibrato (Rate:#0-#F, Depth:#0-#F)
Usage: #4 + vibratorate + vibratodepth
Example: C-300481 4 is the command, 8 is the speed of the
vibrato and 1 is the depth of the vibrato
To keep on vibrating just select the command $ + 00. To change
the vibrato, you can alter the rate, depth or both. Use command
E4- to change the vibrato-waveform.
Cmd 5. ToneP + Volsl (Speed:#0-#F/#0-#F)
Usage: #5 + upspeed + downspeed
This command will continue the current toneportamento and slide
the volume at the same time. Stolen from NT2.0
Example: C-300505 5 is the speed to turn the volume down
C-300640 4 is the speed to slide it up
Cmd 7. #7 + tremolorate + tremolodepth
Tremolo vibrates the volume
Example: C-300794 7 is the command, 9 is the speed of the
tremolo and 4 is the depth of the tremolo
To keep on tremoling just select the vommand #7 + 00. To change
the tremolo you can alter the rate, depth or both. Use command
E7- to change the tremolo-waveform.
Cmd 9. Set SampleOffset (Offs:00-#FF)
Usage: #9 + SampleOffset
This command will play from a chosen position in the sample and
not from the beginning. The two numbers equal the two first
numbers in the length of the sample. Handy for speech-samples.
Example: C-300923 Play sample from offset #2300.
Cmd A. Volumeslide (Speed:#0-#F/#0-#F)
Usage: #A + upspeed + downspeed
Example: C-300A05 5 is the speed to turn the volume down
C-300A40 4 is the speed to slide it up
NOTE: The slide will be called as many times as the speed of
the song. The slower the song, the more the volume will
be changed on each note.
Cmd B. Position-jump (Pos:#00-#7F)
Usage: #B + position to continue at
Example: C-300B01 B is the command, 1 is the position to
restart the song at.
This command will also perform a pattern-break (see below) You
can use this connand instead of restarting as on noisetracker.
Cmd C. Set volume (Volume:#00-#40)
Usage: #C + new volume
Well. this old familiar command will set the current volume to
your own selected. the highest volume is #40. All volumes are
represented in hex.
Example: C-300C10 C is the command, 10 is the volume
(16 decimal).
Cmd D. Pattern-break (Pattern-pos:00-63, decimal)
Usage: #D + pattern-position
This Command just jumps to the next songposition and continues
play from the patternposition you specify.
Example: C-300D00 Jump to the next songposition and continue
play from patternpositon 00.
Or: C-300D32 Jump to the next songposition and continue
play from patternposition 32 instead
Cmd E0. Set filter (Range:#0-#1)
Not available.
Cmd E1. Fineslide up (Range:#0-#F)
Usage: #E1 + value
This command works just like the normal portamento up, except
that it only slides up once. It does not continue sliding during
the length of the note.
Example: C-300E11 Slide up 1 at the beginning of the note
(Great for creating chorus effects)
Cmd E2. Fineslide down (Range:#0-#F)
Usage: #E2 + value
This command works just like the normal portamento down, except
that it only slides down once. It does not continue sliding
during the length of the note.
Example: C-300E26 Slide up 6 at the beginning of the note
Cmd E3. Glissando-Control (Range:#0-#1)
Usage: #E3 + Glissando-Status
Glissando must be used with the toneportamento command. When
glissando is activated, toneportamento will slide a halfnote at a
time, instead of a straight slide.
Example: C-300E31 Turn Glissando on
C-300E00 Turn Glissando off
Cmd E4. Set vibrato waveform (Range:#0-#3)
Usage: #E4 + vibrato-waveform
Example: C-300E40 Set sine (default)
E44 Don't retrig WF
C-300E41 Set Ramp Down
E45 Don't retrig WF
C-300E42 Set Squarewave
E46 Don't retrig WF
C-300E43 Set Random
E47 Don't retrig WF
Cmd E5. Set finetune (Range:#0-#F)
Usage: #E5 + finetune-value
Example: C-300E51 Set finetune to 1
Use these tables to figure out the finetune
value.
Finetune: +7 +6 +5 +4 +3 +2 +1 0
Value: 7 6 5 4 3 2 1 0
Finetune: -1 -2 -3 -4 -5 -mand will retrig the same note before playing the next.
Where to retrig depends on the speed of the song. If you retrig
with 1 in speed 6, that note will be trigged 6 times in one note
slot. retrig on hi-hats!
Example: C-300F06 Set speed to 6.
C-300E93 Retrig at tick 3 out of 6.
Cmd EA. FineVolsl uip (Range:#0-#F)
Usage: #EA + value
This connad works just like the normal volumeslide up, except
that it only slides up once. It does not continue sliding during
the length of the note.
Example: C-300EA3 Slide volume up 1 at the beginning of the
note.
Cmd EB. FineVolsl down (Range:#0-#F)
Usage: #EB + value
This command works just lika the normal volumeslide down, except
that it only slides down once. It does not continue sliding
during the length of the note.
Example: C-300EB6 Slide volume down 6 at the beginning of the
note.
Cmd EC. Cut note (Value:#0-#F)
Usage: #EC + Tick to Cut note at.
This command will cut the note at the selected tick, creating
extremely short notes.
Example: C-300F06 Set speed to 6
C-300EC3 Play note at tick 3 out of 6.
Note that the note is not really cut, the volume is just turned
down.
Cmd ED. NoreDelay (Value:#0-#F)
Usage: #EdC + ticks to delay note
This command will delay the note to the selected tick.
Example: C-300F06 Set speed to 6.
C-300ED3 Play note at tick out of 6.
Cmd EE. PatternDelay (Notes:#0-#F)
Usage: #EE + notes to delay pattern.
This command will delay the pattern the selected numbers of
notes.
Example: C-300EE8 Delay pattern 8 notes before playing on.
All other effects are still active when the pattern is being
delayed.
Cmd EF. Funk Repeat (Speed:#0-#F)
Usage: #EF + funkspeed
This command will need a short loop (#10,20,40,80 etc bytes)
to work. It will move the loop through the whole length of the
sample. Sounds like shit really, but who cares?
Example: c-300EF8 Set funkspeed to 8
To turn off the funking, set the speed to 0
Cmd F. Set speed (Speed:#00-#FF)
Usage: #F + speed
This command will set the speed of the song. The lower the
number, the higer the speed. 1 = fastest, FF= slowest. The
default speed is 6. This will be set every time you load or clear
a song. Speed 6 equals ca 124 bpm.

HOW WE MADE IT! (The indeed true story of DC's birth)
----------------------------------------------------------------
About 6 months ago (that's october 1990) I(il Profeore) got a
copy of the PD-programme called Noisetracker. It was the 1.02
version. It was somewhat of an anticlimax when I realised that it
wasn't fully amiga-compatible. I wanted however to look at code
and perhaps correct some of the many bugs(for example the so-
called joystick-bug. HINT TO DR. SATAN: It was very easily fixed.
It was something with a cmp and a branch I think...). And when I
have speeded up the routines a bit I used the modified
Noisetracker as a sort of module replayer. For about 1.5 month I
did nothing on Noisetracker. But then I decided to make a own
tracker. I got Protracker as an amiga executable file from an
amiga-guy (Thanx Axel!) which I ported to the ST and disassambled
I also ported another amiga-tracker: Startracker by Fairlight
(Once again:Thanx Axel!). I extended the playroutine so it would
be fullt Protracker-compatible. Then the real work began: During
2 weeks I modified almost all of the routines and I wrote many
more.(Puhh!) I thought that i finally could release it. Then I
got Noisetracker 1.5... I said to myself: You got to include all
the new functions... At the same time Bitmaster had tested DC and
showed me a lot of bugs, which I had to correct. And finally:
,after a week of sleepless nights for both me and Bitmaster, we
could proudly and very tiredly release Digi Composer.

was really hard).
The credits for this manual goes to the following persons:
ME (Bitmaster (=Anders Gustavsson) of ISTARI), who have written
almost everything!
MY MOTHER (member of family Gustavsson), who have written the
ripped part of this manual: Protracker commando description
(Amiga).
Il Profesore (Sven Karlsson) of ISTARI, who have written about
the digisound technics and DigiComposer features.
Il Profesore's NOTE: I have also corrected some bugs in the
manual. But I think that Bitmaster have done a rather good job!
There are a few places in this manual that may confuse you
(everything), make you laught (my english) and make you cry (my
jokes). If you find any errors in this manual or the program
please let us know. Write to:
