Page R - Song Mode editing - Fairlight - CMI

 There are two parts to the Fairlight's Page R
1. Pattern Editor
2. Song Editor

This post covers the later.

To swap between the Pattern and Song Editors , type:
E<return>

The SONG EDITOR is used to establish the playing order of the different patterns.


The SONG Editor has two Parts:
1. Song List
2. Sections List


Song List
This is basically a list of PATTERN numbers in the order in which they are to be played. 
It consists of 255 sequential STEPS, with each step containing two items: 
the number of the pattern ("play") and how many times it is to be played ("x's"). 
It can contain letters and numbers. 
Any letters will indicate a link to the "Sections List".


So in the example above, pattern C plays once. This is followed by pattern F which plays once.
Next pattern is G which plays twice.

To navigate left/right on the song list you can either use the light pen or your keyboard.
I think the keyboard is quicker. 
 TYPE: <add> Move window right by one: 
             <sub> Move window left by one. 
       255<add> Move to END. 
       255 <sub> Move to START. 
       nnn <set> Move window to step nnn (1 to 255).


Sections List
This allows you to break down the song into smaller sub-units called SECTIONS.
There are 26 SECTION LISTS identified by the letters of the alphabet: A - Z. 
These are just the same as the song list, except that each section consists -of EIGHT steps.
Five sections are displayed at a time.
The Arrows allow it to be be moved up or down to reveal the desired range of sections. 

You can imagine a section as a collection of patterns.

In the example above, "C" in the Song list & Section List are linked.
C = pattern 17 + pattern 18 + pattern 19 + pattern 20. Each of these patterns plays once.

Furthermore, the section lists themselves can also contain other SECTION LETTERS 
(though a section may not contain its own letter).

To navigate the Section list use the light pen or the keyboard.
Point to the Up/Down arrows or A-Z boxes on the right

Using the Alpha/numeric Keyboard, navigate to the letters on the left.

 TYPE:    X <set> This moves the window to step X (A to Z).

---------------------------------------------------------
There is one extra page which comes in handy when organising your song.... the pattern index.

Pattern Index
The Pattern Index shows which patterns out of the 255 possible pattern numbers are USED. 
This is useful when pattern numbers are not chosen sequentially.
Type :
X<return>


Here we have patterns 1 to 60 used and pattern 99 used.

To return to the previous display TYPE: <clear>


----------------
===============================================

Some common commands:


=================================================
Playing Songs

P,*<return> 
Play whole SONG. (start at bar 1, * = song)

P,*,0 <return> 
Play whole SONG forever. (start at bar 1, * = song, 0 = infinite loop)

To stop type:
S<return>
or hold down<ctrl> & press Escape. 

------------------

Playing Patterns

To display a specific pattern :
P=n<return>

To play a specific pattern:
P,n<return>   (where n= the pattern number)

To play a specific pattern a specific number of times (loop):
P,n,x<return>   
(where n= the pattern number)
(where x= the number of loops)
Note, if you want to pattern to loop infinitely , x=0

To play the past played pattern ,  type:
P<return>

Type S<return> to stop the loop.
