Program Info

Playlists are a useful way to organize your digital music... if you have only a few hundred songs. Once you have thousands of songs, it becomes a chore to modify playlists to suit changing tastes / moods. Also, playlists become completely impractical when you have to suit the musical tastes of various household members. JukeBx changes this. It builds playlists in the background that it creates based on how you, and up to nine other users, rate the song. This enables you to hear the songs you love regularly, and the ones you don't like as much less, while still giving you the variety that rebuilding playlists every day would give you. You can even set JukeBx to rate the songs for you by monitoring your playing habits! Up to ten programmable patterns can be set so everyone can hear music they like equally, or unequally if you set it that way! For example, you can set a pattern that will select 5 songs in a row that you like followed by one your partner likes. JukeBx can be set to use a database that is stored at a remote location and allow you to hear music the way you want it in any room with a networked computer. Multiple copies of JukeBx can use the same database when configured this way and JukeBx can buffer networked songs so once the list is built it can be inderpendant.

JukeBx supports most media files, including most video types, and songs can be imported from playlists or directories. JukeBx can also be used as a playlist generator if you like another player but dislike it's selection ability. JukeBx even includes a Media Filler mode for portable music players which will fill up a directory with a set amount of music.

In addition JukeBx supports offensive song filtering, minimum rating play mode, variable start and end time, ID3 data importing, selectable full screen video, cover / disc image viewing, file type filtering, customization of the user and pattern names, minimize to tray, database browsing, file play count, auto-play, 10 song back, 100 song anti-repeat, anti-artist repeat, and auto minimize. For the advanced / daring users, it is possible to modify some of the values that JukeBx uses to select songs and, for example, change the weightings of the song ratings.

Run "Setup.exe" and follow the instructions. To remove JukeBx use the "Add/Remove Programs" option in the Control Panel. JukeBx stores all its data files in the designated application data area, often "C:\Documents and Settings\USERNAME\Application Data\ACAPsoft\JukeBx ". If you would prefer that it saves in the same directory as JukeBx either run the program from a removable drive, such as a floppy of a USB drive, or delete the "DefSet.txt " file from the JukeBx directory. If you're a new user JukeBx will offer to search a directory for files to import. If on the other hand you have a existing database from pre v1.3 you will need to install v1.3 first to upgrade the database.


First of all, JukeBx needs to know where your files are. JukeBx can either import from directories or from m3u playlist files. Press the "JukeBx Database Functions" button in the toolbar at the top of the window. (This window can also be shown when you first install JukeBx.) In the new window select if you want to import from a playlist or a folder, and then tell JukeBx where it is using the "Select" button. Then press "Import" and wait for JukeBx to finish. When JukeBx has finished, close the window box and JukeBx will start selecting songs. Press the "Play" and JukeBx will start playing. At this time all songs will be rated equally, which needs to be changed to allow JukeBx to work properly. However, there is no need to do it all at once. The recommended method is to run JukeBx in Single mode (the default) and if a song comes up that you wish to hear more or less then you press the "Rating" button and select a different rating. If AutoRate is enabled skipping a song will reduce the rating by a partial score and playing the song in full will increase the rating by a partial score.

Following is a description of all of the functions of JukeBx. Items in Bold are feature or window names.

Main Window

This window is designed to take up the whole screen and present you with a display showing data and an image of what is playing, and a list of what songs are coming up. However, the screen can also be resized to almost any size, but functionally will be reduced (due to less being visible) at sizes less than 800x600. At the top of the window are the Main Control Buttons. Below to the left is the current song title with the rating of the selected user displayed below. Below this is the Status Display which shows a summary of the current songs data, and any selected Quick-Link list below. To the right of this is a space that is used by any Cover Art that you have for your music, any selected Quick-Link list, or for any videos. At the bottom is the Playlist. For more details see below.

Main Control Buttons

Start / Pause Starts or Pauses play. Keyboard Command P
Stop Stops Play
Restart Plays the current song from the start. Keyboard Command R
Back Plays the last played song again. JukeBx remembers the last 10 songs. Keyboard Command B
Skip Plays the next song on the list. Keyboard Command S
Rating If in Single mode, this displays a window which allows the current user to select a rating out of 10 for the current song. It is also possible to delete the song from the database via the same window. If not in Single the Song Details window is shown instead.
Details Shows the Song Details window which displays further information on the current song
Search After asking what you wish to search for a new window is displayed showing the results. From this window you can either directly play songs by double clicking them, or view their details. Please note that this list in not automatically updated so if you make any changes then they will not be reflected in the Search display.

In the left or right side of the top half of the display can be shown a list of related songs to the current ones. If any of these are clicked they will be played. It is better for the left side to be used for text, and the right side used for Cover Art, but if you are running JukeBx as a smaller window the left size might be too small to be used. Only one side can be used for text, and if the right side is used then text is disabled on the right. Up to twenty songs are shown, sorted to show in order of the highest rating. Please note that this feature can be CPU intensive in large lists (5000+) and it not recommended for slower computers. By the right of each song name can be shown its rating for the current user and/or a "V " to indicate it is a video.

Cover Art

JukeBx looks for files of certain names, and as a last resort will pick any image file at random from the directory. Images are stretched up or down to fit the upper right quarter, and they need to be roughly square or they will be distorted. In order of priority JukeBx looks for;

Cover (JPG, BMP then GIF)
Disc (JPG, BMP then GIF)

If JukeBx finds a relevant Cover and a Disc you can toggle between them by left or right clicking on the image.


This shows the list of songs that are coming up next. If you right click in this area a menu is shown. Many of the options are the same as the Status Display, but the others are explained below.

Write cached editsCertain functions, such as AutoRate and hashing store changes and update the DB in one go. These changes happen periodicly and when JukeBx is shutdown, but this function allows you to update the database early.
Test FunctionsEnables and shows certain test functions. These vary and are beyond the intent of this guide.

JukeBx Options

This Window appears when you select the "Options" button on the main window. It allows you to change the user and Alt Pattern names from the boring defaults to more personal ones. This is also where you change the actual Alt Patterns to what is more suitable to your needs.

The Alt Patterns are simple to alter. They consist of a line of single digit numbers which represent the relevant user number. (0 is ten.) For example, a pattern of "123495679" would play a song from User 1 first, the user 2, then User 3, then user 4, then user 9, then user 5 ....and then once at the end of the pattern would start again. This allows you to, for example, play equal music for all members of the household (or less equal if you like!), mix in comedy shorts every ten songs, even use one of the users for ads and run a radio station! The possibilities are (almost) endless!

Other options are explained below.

File TypesAllows you to select what file types will be played and imported. Please note that this is just an internal setting; JukeBx does not associate itself with any file type at a system level.
FilterThe Minimum Play Rating control selects the lowest rated song that will be selected and the Offence control allows you to filter out songs that you feel may offend. (For this to work you must change the settings of offensive songs in the Song Details window.)
Full MovieShows movies in full screen. Keyboard Command F
HistorySets JukeBx to remember the last 100 selected songs (user irrelevant) and prevents any repeat being played (This feature is disabled if your database has less than 200 songs)
TrayMakes JukeBx minimize to the system tray instead of the task bar
Auto BuildBuild lists when JukeBx is on pause
ShutdownWorks with AutoBuild. When both are enabled JukeBx will automatically shutdown the computer if it's not playing after the list has been re-built.
AutoRateHelps you rate your songs by changing rating based on how you play them. Read more about AutoRate here.
No Art RepSets JukeBx to remember the artist of the last 20 selected songs (user irrelevant) and prevents any repeat being played (This feature is disabled if your database has less than 500 songs)
Auto MiniMakes JukeBx auto-minimize when it starts playing
Auto-PlaySets JukeBx to play automatically on program start

NetworkIf you are using JukeBx to access files or databases over a network then you should enable Network mode. This is especially important if you are using JukeBx on multiple computers at once. When enabled JukeBx will make a copy of the database file on the local drive to speed access for non-writing functions and reduce conflict. Read more about Network mode here.
BufferWorks with Network. If enabled JukeBx will copy the current play list to the local computer so it can keep playing no matter what happens to the server connection. The amount of storable songs can be changed Read more the Buffer function here.
Show RateShow the rating of songs in a Quick-Link list

Database Functions

This window is for altering database settings. Its functions are explained below.

FolderSets JukeBx to import from folders (The Folder import is recursive, that is, subdirectories are checked as well)
PlaylistSets JukeBx to import from any M3U compatible playlist files
SelectEnables you to select the folder or file to import from
ImportStarts importing. The status is displayed below (If you close the window the import is stopped)
FunctionsSee below for details on the functions.

Details on the functions

Save DB as playlistSaves the database as a M3U playlist file
Remove DuplicatesSearches the database for double file names (NOT song names) and deletes them
Copy RatingsCopies song ratings from one user to another
Upscore SongsPut simply, makes all songs for the selected user more likely to be played, regardless of rating. Put in a more complicated way, it put in the song score twice the value of the breakpoint. For more information, refer to JukeBx Internals.
Remove missing filesRemoves from the database any songs that cannot be opened
Reload Song DataRe checks all files for updated ID3 data (Be sure to have Lock Name enabled if you wish to protect any entry)
ReDefault SongsResets all song ratings to the default from the selected index number
Undelete AllUn deletes all previously deleted song records that have not been overwritten
Reset Start PointsChanges the start points for each song to zero.
Sort by NameRe-orders the database so it's in order of song name.
Sort by ArtistRe-orders the database so it's in order of song artist.

Song Details

This window shows details of the song extracted from the database. Most of the entries are self explanatory, however it should be noted that if you change anything from the generated data and plan to use the "Reload Song Data" function, be sure to have the Lock Name option checked. Otherwise JukeBx will happily "correct" all of your changes.

Status Bar

The Status Bar of JukeBx provides a lot of important data and some of its functions are explained below. Please note that many are only shown if certain options are enabled.

JukeBx ReadyShown when JukeBx is not playing or building.
JukeBx PlayingShown when JukeBx is playing.
JukeBx PlayingWhen selecting a song to add to the list this is shown. Please note that JukeBx won't be as responsive while building a list.
JukeBx PostingThis means that JukeBx is looking up song data and adding it to the list. Please note that JukeBx won't be as responsive while building a list.
Un-BufferedIf Network and Buffered mode is enabled you'll see this if a song is being played that is from the remote source.
BufferingShown when JukeBx is copying remote songs to the local harddrive.
BufferedIndercates JukeBx has finished buffering
Partially-BufferedShown if the buffering is finished but the buffer is too small to buffer the whole list.
HashingShown if JukeBx is creating a hash for the file. Read more about this here.
Clearing CacheShown when JukeBx is updating the Database of any cached edits.
DB OfflineIf Network mode is enabled this is shown when JukeBx can't access the main DB. (This isn't an error conditon.)

JukeBx Internals

On this window are the defaults that are used when JukeBx is deciding what song will play next. Altering these setting can completely ruin the way that JukeBx works, but that is why the Default button is there. Even so, changing the settings here should only be done if you feel that you that you want a more or less distinct difference between the ratings. The way that the default ratings are set, a song rated as 2 will be played twice as much as a song rated as 1. This means that a song rated as 10 is 512 times more likely to play than one rated as 1. A possible change is to double all of the values, including the Target Value, except the value for 1. This will mean that any song rated as one will 1 rarely play. (The programmer has his programs set that way.) The Alternate button will change the settings to this configuration.

Also here is the Network mode setting, which is explained here, and some test data which has no user purpose and thus won't be explained here.

For the curious, the way the JukeBx works is that is has a running count for each songs for each user. When a song is to be selected, one is chosen randomly from the database and its running count is compared to the Target Value. If the number is less that it then the songs Rating Value is added to the running count and another is selected. This goes on until it finds a song with a high enough running count. When it does then it reduces that songs running count to zero and then starts again. Thus the Target Value must be above the highest Rating Value otherwise songs rated at that value will play a lot. Even so, the decision is yours.

Also on this window is the setting for the default rating for imported songs. This gives a rating of 6. As a side note, remember that the ratings can mean what you want them to mean. 1, for example does not have to mean that you think the song is bad; 1 simply is a song that you want to hear less than a song rated as 2. Thus 6 should mean that you really like it. But, once again, it is your choice.

The other option on this page is "LAME Check". This setting will advance the the song start point to 540 when the song is imported if you are using LAME encoded MP3 files. This is because LAME adds extras silences at the start of each song and the some decoders do not like this. We have found that this isn't as much of a problem as it used to so this function is now an option, but if this happens to you we advise you to enable this. In some cases it is necessary to further advance this to something a few thousand later.

The last feature on this page is AR Speed, which is the Auto Rate speed. The way Auto Rate works is it up rates a song after a complete play, and down rate on a skip. The amount that changes depends on the AR Speed setting;

Slow 1/8 Rating value
Normal 1/4 Rating value
Fast 1/2 Rating value

To understand how this works you first must remember that the changed value is the hidden value, not the Visible Rating. Thus when set to normal using the default rating values songs will go down after two backs, and up after 4 plays. That is, if the song has a Visible Rating of 6 its Rating Value would be 64. 1/4 of 64 is 16, so when skipped it goes down to 48, which equates to a Visible Rating of 5. Next time it's skipped it looses 12 making it 36, leaving the Visible Rating as 5. But on the next skip it looses 9, becomes 25 and thus has a Visible Rating of 4.

Going the other way and starting again with a Visible Rating of 6, adding 16 to 64 makes the Rating Value become 80, which still equates to a Visible Rating of 6. Next time it plays it gains 20 making it 100, leaving the Visible Rating still at 6. Then on the next play it gains 25, becomes 125 and thus still has a rating of 6. However on the next pass it goes to 156 giving it a Visible Rating of 7.

How this works for you long term is hard to be sure about, but remember that if it's too slow or too fast it can be changed.

Network Mode

From the start JukeBx was designed for a home enviroment, and thus it has the ability for multiple copies of JukeBx to be running off the same database. To do this you need to have all the music as well as the database on a network share that all computers can access most of the time. By default JukeBx stores the database file in the normal user data directory, but it's easy to move it. To do this;

1. Open the About box via the right-click menu.
2. Select from the combo box to the bottom left Prog Dirs and then press the Open Dirs button to the right. Close the About box.
3. Open the destination network folder and then copy the JukeBx.lbf file to this folder.
4. Open the Database window, press the ChangeDB button and then select the new file location. Close the Database window.
5. Open the JukeBx Options window, and enable Network and Buffer as well if the local drive has around a GigaByte free.

With Network enabled JukeBx will keep a local copy of the database for read related purposes. The amount of songs buffered depends on the Buffer Size setting. Do remember that this can consume a large amount of hard drive space.

File Hashing

In this version a long planned feature of a file ID has been added to JukeBx. This allows the database to identify a file in more ways than just the filename. There are many potential uses for this, but to name a few it will be easier to find doubles and to detect moved or re-imported files. However, for the moment this featre is used only for the DB Caching functions.

To further explain, when the DB is shared among several computers if one copy of JukeBx kept doing changes it would prevent others using it. For this reason a new DB Caching function was written. This allows (at the moment) up to 100 DB changes to be stored and then processed in one go. Writing this was important to the long term plans of JukeBx so this was a good excuse to do it now. When an DB change is cached four things are stored; the DB record, the previous data, the new data, and as a piece of extra safety an "unique" ID mark. In this case it's the new piece of data that's labelled as "ID". This is a hash made via a custom derivative of the Fletcher's checksum that is based on the music file itself. These 4 pieces are stored and when it's time to write the cached data they need to match. If they don't the change is abandoned to avoid changing the wrong record (if for example the DB was re-ordered) or overwriting another edit.

New imports are hashed as they are imported, and existing songs will be hashed in the background.

JukeBx Media Filler

The JukeBx Media Filler is actually the same program as JukeBx, but it has a different window, and a different function. It is accessed by either the Right click Menu in the Status area, or by opening JukeBx with the command line switch /f. The Media Filler only works if JukeBx is set up already as it uses the most of the settings that are used in the Player mode. However, some settings can be customised for the Media Filler mode, so, for example, you can prevent file types that your player does not support being copied across. When JukeBx is run for the first time in Media Filler mode these settings are copied across, but they are saved in a separate file. Most settings are already explained in other parts of the ReadMe, but some functions are exclusive to this function.

File SizeSelects how much songs will be copied across, measured in MB. You can also set JukeBx to keep copying until there is no room left by setting it to Fill.
Empty DirDeletes the contents of the selected output directory prior to filling it (Confirmation is needed prior to the deletion)
Add NumberAdds a number prefix to each file as it is copied over so you can play them in the same order that they were generated simply by playing the music in alphabetical order. This function is useful if you like playing music randomly but do not like the randomness of your device.
ResetRestores the default settings

Command Line Options

JukeBx supports some Command Line Options.

Programmers Notes

This version is a massive tweak from the last, with many little features added. Much of the internals have been rewritten too.

JukeBx has been tested on Win2000, WinXP, Vista and 7.

System Impact Statement

We go to great lengths to reduce system impact, but we feel that it is still important to explain here what our programs do to your system. If you feel we are missing something, or you need further clarification, please contact us.

RegistryJukeBx does not use the registry. The installer that comes with JukeBx uses the registry only for the required un-installation data, and not at all if you use the "Extract Only" mode.
System SettingsJukeBx does not change any system settings.
FilesAll of its program files are stored in the installation directory, and all of its data files are stored in the designated application data area, often "C:\Documents and Settings\USERNAME\Application Data\ACAPsoft\JukeBx". If you would prefer that it saves in the same directory as JukeBx either run the program from a removable drive, such as a floppy of a USB drive, or delete the "DefSet.txt" file from the JukeBx directory. These directories can be opened via the About box.
NetworkJukeBx and its installer do not access the internet in any way, but the ReadMe does have three graphic files that are stored on the internet. (They are not used as web-beacons, merely spacers and images for the payment processors.)
CPUJukeBx has some CPU intensive functions, such as the quick-list, however we have tested JukeBx on a Intel Atom and it works without any problems.
MemoryJukeBx is memory demanding only if your cover image files are excessively large, that is greater than 5 MB.
