Patterns
--------
Any piece of music written with SoundTracker 2.1 is build up from patterns.
SoundTracker holds a table with information about the sequence in which
these parts must be played. With 'Position' you determine your position
in the table. With 'Pattern' you define what pattern to play at that
position. 'Length' defines the total size of the table.
Keys
----
The keys on your Amiga have been grouped to represent the layout of a
two-octave piano-keyboard. You can "shift" the keyboard one octave up or
down with the aid of the F1 and F2 keys, thus incrementing the range of
the keyboard to three octaves.
Editing
-------
Cursor-keys move cursor.
shift + Cursor-keys move cursor fast.
alt + Cursor-keys move cursor fastest.
F6 - Set cursor to first line of pattern.
F7 - Set cursor to 16th line of pattern.
F8 - Set cursor to 32th line of pattern.
F9 - Set cursor to 48th line of pattern.
F10 - Set cursor to last line of pattern.
DEL - Delete note under cursor.
shift + F3 - Cut track of current pattern and copy into copy-buffer.
shift + F4 - Copy track of current pattern into copy-buffer.
shift + F5 - Copy buffer to track of current pattern.
alt + F3 - Cut the whole pattern and copy into copy-buffer.
alt + F4 - Copy pattern into copy-buffer.
alt + F5 - Copy buffer to current pattern.
Special Keys
------------
To quit SoundTracker 2.1 point the mousepointer at 0,0 and press:
alt + shift + left and right mousebutton together !!!!
Instruments
-----------
You can use up to fifteen different instruments in one music-piece.
All instruments are listed in the preset-list. The volume is always
64 but you can change it to each value between 0 and 64.

Note to
be played.
Note This is simply the note that must be
---- played by that particular instrument.
Inst# This is the number of the instrument that must be used to play
----- the note. When the instrument number is zero, the last selected
instrument will be used.
Command This number tells SoundTracker what special functions must be
------- performed while playing the note. These functions are:
0 - Normal play or arpeggio.
1 - Portamento up.
2 - Portamento down.
B - Position jump!
C - Set volume.
D - Pattern break!
E - Set filter on/off
F - Set speed.
Info This byte contains the additional information for the commands.
----
Arpeggio Arpeggio is used for simulating accords. It does this by
-------- rapidly changing the notes while playing an instrument.
Arpeggios are selected whenever the info byte has a non-zero
value and no other commands are selected.
When arpeggios are used, SoundTracker looks five times during
the play of one note, at the information contained in the info
byte. Each nibble (4 bits) in this byte defines
how many notes SoundTracker must add to the the note currently
playing. In each of the five passes SoundTracker does the
following with the information contained in the info byte :
1 - Add the first nibble to the current note.
2 - Add the second nibble to the current note.
3 - Play the current note.
4 - Add the first nibble to the current note.
5 - Add the second nibble to the current note.
Portamento Portamento is used for 'sliding' of the instrument.
---------- If portamento is in use, the information contained in
the info byte will be added to (or subtracted from) the period
of the note playing in each of the five passes.
Example: D#2 3208 Slides down $08
--- 0208 Slides down $08
--- 0108 Slides up $08
--- 0210 Slides down $10 (=16)
etc.
Position jump The position jump command will do the same like the
------------- pattern break command, but the info byte gives the
playroutine the no. of the position.
Example: E-2 3B04 - Break the pattern and jump to position 4
--- 0000
--- 0B06 - Break the pattern and jump to position 6
Volume One of the enhancements that the V2.1 version provides is the
------ ability to change the volume at any time during play.
When command $0C (=12) is selected, the volume is set to the value
contained in the info byte. The volume will remain at this level
until a next SAMPLE is played. At this time, the volume is
reset to the default volume level of that sample.
Example: C#1 1C22 - Set volume to $22 (=34) and use instrument # 1 to
play the C#1 note.
D-2 0000 - Use instrument # 1 to play the D-2 note.
(Volume level remains at $22 (=34))
B-1 1000 - Use instrument # 1 to play the B-1 note and
set volume to default value for that
instrument.
Pattern break Pattern break is used to create shorter patterns than 64
------------- notes. The note with the $0D command will be played and
after that the next pattern in the pos-table will be played.
Example: A#3 1D00 - At this point the pattern interrupts.
--- 0D00 - Look upper line.
C-1 0D30 - Look upper line.
Filter This Soundtracker version allows you to turn
------ the lo-pass filter on/off.
Example: G#2 1E01 - Turns the filter and the power-led off.
--- 0000
E-1 1E00 - Turns the filter and the power-led on.
Speed This function allows changing the speed during play.
----- You can only enter a speed between 01 and 0F.
Setting the info byte to zero doesn't effect anything.
The normal speed is 6.
Example: D-2 4F05 - Set speed to 5
--- 0000
E-1 0F00 - Nothing happens to speed.
--- 0FC3 - Set speed to 3
G-2 2F06 - Set normal speed
