yes, to give credit to the author.

Wherever you are, ./ refers to that spot. so you want to be at root level where your compiled bin are, then ./compiledprogramname if you use the other \ slash if linux or mac it wont work.

 

abledecoder. ableton encrypted aif outside of ableton

That's great, but from what source???

 

I've managed to do it.
here are my files
https://workupload.com/archive/kYYYMLnFUZ
the binary for mac to run with terminal
and a python script to batch process

 

For someone who wants to crack the Pack from the Ableton site, replacing original .aif samples with decoded .aif samples wasn't enough. The .adg and .alc(MIDI clips) can still complain about missing file errors.

You also need to replace some strings in the .adg and .alc files.
The .adg and .alc files are zip-compressed XML files, all these XML files contain a unique ID related to the Pack and file checksum of the original .aif samples, you have to replace it to get the decoded samples to work properly in a licensed Ableton Live.

The unique ID of the Pack is written in the file `/path/to/Some Pack/Ableton Folder Info/Properties.cfg` (reference: https://audiosex.pro/threads/how-to-create-your-own-alp-files.78881/#post-828162)

Code:

String PackUniqueID = "www.ableton.com/256";

you need to replace the number `256` with a bigger number, from my experience, a 5-digits number would be fine,

Code:

String PackUniqueID = "www.ableton.com/25612";

and some XML attributes need to be replaced in every .adg file and .alc,

Code:

<LivePackId Value="www.ableton.com/256" />
<OriginalFileSize Value="12345" />
<OriginalCrc Value="67890" />

replace it to,

Code:

<LivePackId Value="www.ableton.com/25612" />
<OriginalFileSize Value="0" />
<OriginalCrc Value="0" />

Do it to all .adg and .alc files, now the presets and clips will load normally in a licensed Ableton Live.

I wrote a script to do that, it works seamlessly on macOS.

1. use the `rabledecoder` from https://github.com/motabass/abledecoder to decode all samples in the Pack and replace the original samples in the Pack.
2. save the code below as `fix_ableton_pack.sh`
3. open the terminal and run `./fix_ableton_pack.sh ~/Music/Ableton/Factory Packs/SomePack 23456`. `~/Music/Ableton/Factory Packs/SomePack` is the path of the Pack you want to crack, 23456 is just a random number.

Now you can enjoy the cracked Pack in a licensed Ableton Live. The only downside is now the size of Pack will be increased because all the .adg and .alc files are uncompressed.

Code:
