Hello, I've been trying to rescue a track that won't open for some reason, I get an error message when I try to load a track on my MPC LIVE 2, I've been trying to open the VPJ file with all types of text editors but all I see is this kind of gibberish..

I thought it might be this file alone but when I did the same with files that actually do open without any problem I still get the same type of gibberish, do VPJ files not open with text editors anymore? Is there a text editor in specific that let's you read these VPJ files?

hello all . I need some advice or help, thanks for reading

Today I had a good (standalone) session on a project, few hours of work. after saving a .xpj project, save was successful and it came back on main screen.

but before properly shutting down, the unit (mpc one +) I accidentally disconnect the Powersupply. At next boot, I have the classic "error loading myproject.xpj " message appearing in the first seconds of load process.

I try to open the .xpj file in text edit , but using keka or the unarchiver, it says the archive is uncomplete.

I've seen that video that could be a good starting point, but i fin no way to get it ungzipped.

EDIT : I managed to unzip the xpj file using" the unarchiver" app , only need to add the .txt extension after the unzip.

I had some 5 audiotrack recorded files that were not referenced in the .xpj text file, but that were present in the relative data folder.

I carefully added their references to the text file, using the same notation and signs, exactly as other files...
and changed back the extension to .XPJ, but no success to open the project in my mpc.

I think maybe renaming the extension is not enough ? did someone succeed to edit XPJ files in text editor, then save the changes and put the file back on a gzip archive format that i could then change to .xpj to make it work ?


thanks

If I'm editing a single file I just unzip the XPJ or XTY using betterzip (or whatever zip app, doesn't really matter). So if the project is called 'My Project' this will give me a file called 'My Project'. I do not add a .txt. extension.

I then open that file in my preferred editor (I use Coda - it formats the code as JSON which makes editing much easier).

After editing I compress it using Kepa set to 'Gzip'. Rename the extension from .gz to .xpj.

For work on multiple files I prefer to use php which has gzip functions included (php isn't ideal but it's what I know, would assume something nodejs or python would be faster)

Thank you very much Tutor, i will try this way

i think I damaged my original project file, but when comparing to a working one, I can't see no big differences except the missing file references. Let's try to save this work :)
