|   Information about James Procter's PlayList feature

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

Part of James Procter's excellent contributions to the PD
!PlayerMod application was that of a 'PlayList' file, and his
truncated comments on it are included below.

Please do not separate this file from its application !

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

Initial implementation by James Procter 2nd January 1991   
                                                        
This is the specifications for the P.D. !PlayerMod Desktop
Soundtracker play 'manager' by Nick Smith, Matt Durys, and The
Mad Dog. It allows the creation of programmes of soundtrackers
to be played, and controls the method of switching from one
module to the next.

At the time of writing, the implementation allows fading in
two ways, either an autofade or a standard fade - the autofade
only occurring if the last event in the module has no
instruments active. In both cases the fadetime can be adjusted
and ....

Playlist Files : Filetype &444 (Provisional)
Commands       :

The commands fall into two types, those that apply to the
overall playlist where applicable, and those which apply to
only one song entry in the playlist.

General Commands
================

'|'             Rem statement, lines starting with this will
                be ignored.
'fadetime xx'   Set overall fadetime to xx polls. This means
                that any song entries which do not specify a
                fadetime, and do not disable fading will have
                this fadetime. If this command is not
                included, the overall fadetime will be set to
                that which is used for the fading when 
                'playing a directory'.
'version xx.xx' This is the minimum version number of
                !PlayerMod needed to use this playlist. This
                can be anywhere in the file, as long as it is
                not remmed out. !PlayerMod will give an error
                if no valid version number is given.
'"'             Start of a song entry.

The playlist interpreter will strip all leading spaces from
the lines, and command recognition is not case dependent.

Song Entries
============

These are lines starting with a quote : '"'
The general syntax is as follows :

"<Full Song Pathname>" [<fadetime>|{command}]

With just the song pathname, !PlayerMod will just play the
song and use the semi-intelligent autofade using the overall
fadetime.

<fadetime> is a value in polls, again as in the general
command 'fadetime', and will have the effect of causing the
player to play the song and fade using the semi-intelligent
fading system with the specified fadetime.

{command} can be one of the following :

'nofade'        This will turn all fading off, and the next
                song will be played immediately at the end
                of this song, with no fading out.
'fade [xx]'     This turns off the 'instrument detection'
                feature of the fading system, so that the
                module will fade out irrespective of the
                current instrument states at the end of the
                song. The fadetime can be set [xx] if wished
                but the overall setting will be used if not
                specified.

That's about all I can say, hope you find this useful....
