Genica Portable MP3/CD Player
The MPTrip is a [relatively] inexpensive portable audio player that plays CD-ROM discs [in the ISO 9660 format used by most computers] containing mp3-encoded audio files. It also plays [regular] audio compact discs, including those written with a CD-R or CD-RW. It is made by a rather obscure manufacturer, though it does seem to play well. It may be purchased from the following retailers:
If your computer is not already capable of playing mp3 audio, mp3.com offers a helpful list of software players.
- The Computer Geeks ($99, requires reservation; your credit card will not be charged)
- EasyBuy2000 ($115, no registration; your credit card will be charged)
Decide for yourself
Is the MPTrip worth buying?
Using directory mode
If you already have the MPTrip, you know that the manual is incomplete and poorly-written. One of the most useful features of the MPTrip is its directory mode; it is difficult to go between songs and directories without it. Yet this feature is one of the most poorly documented. I was able to make it work, thanks in part to the instructions at EasyBuy2000. (If you are unfamiliar with the MPTrip, directory mode restricts playback to a given directory; once its songs have been played, the player will shut off immediately.)
Entering directory mode
When directory mode is enabled, you should be able to scroll through a hierarchical list of directories. If the middle set of numbers stops blinking, the player might not allow you to scroll through the list. It may take some time to get used to due to the small size of the display; the player cannot display the directory structure as a tree. Within any directory, the player assigns numbers to subdirectories in the order they were recorded (always from 1 to n, regardless of hierarchy level).
- When you first turn on the player, it will be in its default play mode ("all play," in which all songs are played [more or less] sequentially). To toggle between modes, hold down the "play mode" button; release it when the "Dir" indicator appears (it is possible to go between modes without having to hold down the play mode button the whole time, though you will lose your place in the CD).
- After the Dir indicator appears, press the "rec/dir/file" button once or twice until the display reads DIY (maybe the misspelling was intentional; I had to figure out myself what rec/dir/file meant).
Note: When you enter directory mode, your initial "working directory" will be the one in which the currently playing song is located.
Changing between directories
To climb up to the parent directory
- Make sure that the currently-selected subdirectory is 01 (00 if the working directory does not contain any subdirectories); if 01 is not selected, use the "preview" button to scroll up the list.
- Press the "preview" button (the topmost oval-shaped button to the right of the display) once more.
To crawl down to a child directory
- Select the subdirectory you want to make your working directory (tap the "next" button to scroll down; press the "previeq" button to scroll up. It is not possible to scroll up when subdirectory 00 or 01 is selected; scroll down instead.
- When you have selected the desired subdirectory, hold down the "next" button until the display reads "xx-down".
Changing between songs
Once you have selected your "working directory", its contents will be played in the order they were recorded to the CD-ROM. As always, those misplaced "preview" and "next" buttons retain their usual function.
- I found that it helps to have a "shallow" directory structure when possible
- If you record entire albums to CD, make sure that each album occupies its own directory; it will be difficult to listen to the whole album unless you use directory mode.
- If you don't mind sacrificing shuffle play, directory mode can be used to emulate a "sleep" mode
Printing a list of songs
Note: In its default mode, my MPTrip did not number songs in the order
that I would have expected. This problem does not occur in directory
In a posting to the mp3.com
bboard, LorenR suggested that Adaptec Easy CD
Creator allows you to make the problem go away by selecting View-->Show
If your CD-ROM mount point is /mnt/cdrom, try:
mount /mnt/cdrom ; find /mnt/cdrom -type f -printf %f\\n | nl > playlist.txt
If GNU findutils and textutils are installed, playlist.txt will contain a numbered playlist.
Courtesy of EasyBuy2000. If your CD-ROM is drive D, try:
tree D:\ /f > playlist.txt
dir D:\ /s /b > playlist.txt
- Select the icon representing your CD-ROM drive
- Drag the icon into the playlist window in Winamp
- Sort the playlist by path and filename
- Export your playlist to HTML format
- Print the formatted playlist inside your browser
Consider downloading mp3report David Parker has written a remarkable
open-source program that makes
playlists based on HTML templates. It requires the Perl scripting language, though I feel it
is worth the trouble. I have included a few modifications I made to the
program that make it less difficult to use directory mode (though you
should download the original version anyway; the author's documentation
and sample templates are helpful):
