trackers will search through all patterns when loading.
Noisetracker uses this byte for restart, but we don't.
952 128 Song positions 0-127. Each hold a number from 0-63 that
tells the tracker what pattern to play at that position.
1080 4 The four letters "M.K." - This is something Mahoney & Kaktus
inserted when they increased the number of samples from
15 to 31. If it's not there, the module/song uses 15 samples
or the text has been removed to make the module harder to
rip. Startrekker puts "FLT4" or "FLT8" there instead.

Offset Bytes Description
1084 1024 Data for pattern 00.
.
.
.
xxxx Number of patterns stored is equal to the highest patternnumber
in the song position table (at offset 952-1079).

Each note is stored as 4 bytes, and all four notes at each position in
the pattern are stored after each other.

00 - chan1 chan2 chan3 chan4

To determine what note to show, scan through the table until you find
the same period as the one stored in byte 1-2. Use the index to look
up in a notenames table.

This is the data stored in a normal song. A packed song starts with the

EFFECT COMMANDS
---------------
Effect commands on protracker should
be compatible with all other trackers.
0 - None/Arpeggio 8 - * NOT USED *
1 - Portamento Up 9 - SampleOffset
2 - Portamento Down A - VolumeSlide
3 - TonePortamento B - PositionJump
4 - Vibrato C - Set Volume
5 - ToneP + VolSlide D - PatternBreak
6 - Vibra + VolSlide E - Misc. Cmds
7 - Tremolo F - Set Speed

E - COMMANDS
------------
The E command has been altered to
contain more commands than one.
E0- Filter On/Off E8- * NOT USED *
E1- Fineslide Up E9- Retrig Note
E2- Fineslide Down EA- FineVol Up
E3- Glissando Control EB- FineVol Down
E4- Vibrato Control EC- NoteCut
E5- Set Finetune ED- NoteDelay
E6- Patternloop EE- PatternDelay
E7- Tremolo Control EF- Invert Loop

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 on monotone ones.
Example: C-300047 C-major 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: $1 + 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 is the portamentospeed.
NOTE: The portamento will be called as
many times as the speed of the song.
This means that you'll sometimes have
trouble sliding accuratly. 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 like 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.
You don't have to worry about which
direction to slide, you need only 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 is the note to
slide to, 3 the command,
and 5 the speed.

Cmd 4. Vibrato [Rate:$0-$F,Dpth:$0-$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 $4 + 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 [Spd:$0-$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-300503 3 is the speed to
turn the volume down.
C-300540 4 is the speed to
slide it up.

Cmd 6. Vibra + Volsl [Spd:$0-$F/$0-$F]
--------------------------------------
Usage: $6 + upspeed + downspeed
This command will continue the current
vibrato and slide the volume at the
same time. Stolen from NT2.0.
Example: C-300605 5 is the speed to
turn the volume down.
C-300640 4 is the speed to
slide it up.

Cmd 7. Tremolo [Rate:$0-$F,Dpth:$0-$F]
--------------------------------------
Usage: $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 command $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 2 pages below).
You can use this command instead of
restart as on noisetracker, but you
must enter the position in hex!

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.
(Programmers do it in hex, you know!)
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
song-position, and continues play
from the patternposition you specify.
Example: C-300D00 Jump to the next
song-position and continue play
from patternposition 00.
Or: C-300D32 Jump to the next
song-position and continue play
from patternposition 32 instead.

Cmd E0. Set filter [Range:$0-$1]
--------------------------------
Usage: $E0 + filter-status
This command jerks around with the
sound-filter on some A500 + A2000.
All other Amiga-users should keep out
of playing around with it.
Example: C-300E01 disconnects filter
(turns power LED off)
C-300E00 connects filter
(turns power LED on)

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 Ctrl [Range:$0-$1]
------------------------------------
Usage: $E3 + Glissando-Status
Glissando must be used with the tone-
portamento 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-300E30 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 -6 -7 -8
Value: F E D C B A 9 8

Cmd E6. PatternLoop [Loops:$0-$F]
----------------------------------
Usage: $E6 + number of loops
This command will loop a part of a
pattern.
Example: C-300E60 Set loopstart.
C-300E63 Jump to loop 3
times before playing on.

Cmd E7. Set tremolo waveform
[Range:$0-$3]
----------------------------
Usage: $E7 + tremolo-waveform
Example: C-300E70 Set sine(default)
E74 Don't retrig WF
C-300E71 Set Ramp Down
E75 Don't retrig WF
C-300E72 Set Squarewave
E76 Don't retrig WF
C-300E73 Set Random
E77 Don't retrig WF

Cmd E9. Retrig note [Value:$0-$F]
---------------------------------
Usage: $E9 + Tick to Retrig note at.
This command 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 up [Range:$0-$F]
----------------------------------
Usage: $EA + value
This command works just like the

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 like the
normal volumeslide down, except that

6 at the beginning of the note.

Cmd EC. Cut note [Value:$0-$F]

Note that the note is not really cut,
the volume is just turned down.

Cmd ED. NoteDelay [Value:$0-$F]
-------------------------------
Usage: $ED + ticks to delay note.
This command will delay the note
to the selected tick.

notes before playing on.
All other effects are still active
when the pattern is being delayed.

Cmd EF. Invert Loop [Speed:$0-$F]
---------------------------------
Usage: $EF + Invertspeed
This command will need a short loop
($10,20,40,80 etc. bytes) to work.
It will invert the loop byte by byte.
Sounds better than funkrepeat...

To turn off the inverting, set
invspeed to 0, or press ctrl + Z.

The 6 and 8 channel mod files differ from the normal mods in two ways:

1) The signature string "M.K." at offset 1080 is either "6CHN" or "8CHN".
2) The pattern data table starting at offset 1084 stores 6 or 8 notes for
each pattern position position.
