For this specific error message during sync, that is “Source file [some path] does not exist”, you can do the following in Windows.
[LIST=1]
[]Note the file name. In the example for this thread, the file name is “52A7F043.hash.bcf”.
[]Go to the directory that’s supposed to contain that file. In this example the directory is “E:/Musik/Beatbuddy/Workspace/user_lib/projects/Default Project - Project/EFFECTS/”. So, you would use the Windows Explorer to go to that directory.
[]Look for a file with the same name as the file causing the problem. In this case look files named "52A7F043.".
[]There should always be an XXXXXX.bcf file, an XXXXXX.wav file, and SOMETIMES an XXXXXX.hash.bcf file. If the BeatBuddy is complaining about a .hash.bcf file missing as in this example, copy the .bcf file with the same name and change the extension to “.hash.bcf”. If BeatBuddy is complaining about a .bcf file missing, then copy the .hash.bcf file with the same name and change the extension “.bcf”.
[]Synchronize the project. This will copy the missing .hash.bcf or .bcf file to the BeatBuddy and you should be good from there on.
[/LIST]
I don’t know why sometimes BeatBuddy fails to generate the .hash.bcf or the corresponding .bcf files that give it information about the .WAV files in the EFFECTS directory, but when I looked at the .hash.bcf and .bcf files that were not giving me problems with a HEX editor, the paired .hash.bcf and .bcf files always contained exactly the same data, so if one is missing, you can copy the other and change the extension. If both are missing, or if the corresponding WAV file is missing, then you need to go find the files in the default SD image and copy them into the right directory.
