Jukebox
Jukebox Controls >| or >> Skip Track Stop Key Stop Jukebox Random Play This option plays mp3 files in the MP3 directory and its subdirectories at random. The random play has a 10 track playlist history buffer to prevent the same song being played twice. Random Play Track Selection Logic Track are selected by going to the MP3 directory and counting the number of folders and files in the directory. 1. The program then generates a random number and goes to the file or folder indicated by the random number. If a folder is found the file program repeats step 1. If a file is found the program proceeds to step 2. 2. The file found is checked against the playlist history buffer. If the file is not in the history buffer or we have being looking for more than 2 seconds it is played otherwise then program moves back to the MP3 directory and goes to step 1. If you have less than 10 tracks in your MP3 directory the Jukebox will take longer to change track as it will time out looking for unplayed tracks. PlayList Sequential Press OK on the Playlist Sequential menu and the tap will display a menu of playlist files found in the directory /PlayLists. Select the list you want to play and press OK to start playing the mp3's in the order they are listed in the playlist. PlayList Random Press OK on the Playlist Random menu and the tap will display a menu of playlist files found in the directory /PlayLists. Select the list you want to play and press OK. The program will ask if you want to reset the play list history. Select Yes to clear the history or no to keep. The program will then start playing the mp3's in the playlist in random order. Playlist Random mode has a playlist history buffer that records the last 50 tracks played. If you have 100 tracks in your playlist once the 100th track is played the play history buffer is cleared completely. PlayList Directory Playlists are stored in the directory PlayLists which you need to create using Altair. It appears that this is case sensitive so you must name the directory as specified. The PlayLists directory also stores playlist history files which have the extension .hst.

PlayList
Creation
I have my mp3
database on both my PC and on the Topfield.
On the Topfield
the mp3's are stored in the directory /MP3.
On the PC the
mp3's are stored in the directory C:\Music
The Playlist is
a text file listing the full path and filename of the mp3 to play. (See sample
Playlist01.m3u)
The extension on
the playlist must be .m3u
On the PC I use
MusicMatch to manage the mp3 database
and create playlists. I then use Altair
to transfer the playlist to the PlayLists folder on the Topfield. I have set
Mp3Prefix=c:\music\ in the ProgressBarKeys.ini file so the program knows to
change the playlist paths from c:\music\ to MP3.
PlayList History
The Jukebox
keeps track of each track played in a Playlist history file for each playlist
in the PlayLists directory and Random.hst for the random mode playlist
history. The playlist history records only the track name not the path to the
track. The playlist history will store up to 50 tracks for playlist random
mode and 10 tracks for random mode.
