Extracting wav from ppi ppf?

Help to extract wav from ppi ppf to reduce the frequency of wav files being discredited and to reduce the extension package from 770 to 670.

Hi --

On Windows, if someone wants to, they can poke around the installed packs in:

C:\Users\XXX\AppData\Local\Yamaha\Expansion Manager\Packs\

where XXX is your user name. One needs to be aware, however, that YEM uses a database manager that names directories and files with Global Unique Identifiers (GUID) instead of human readable names. You can find waveform files within the pack directories. The pack directories contain two hidden files -- .index and .catalog -- which assist navigation a little bit.

If you're lucky, a waveform file may be in a standard format (e.g., WAV). Yamaha protected content is usually in their proprietary format which is virtually unsupported by third party tools. Yamaha compression is their secret sauce.

You can also find UVF voice definition files down there, too.

If you go exploring, good luck! Be prepared to deal with highly cryptic naming and be ready to identify file formats, etc. by magic numbers. Also, whatever you do, don't change anything unless you really, really know what you're doing...

Have fun -- pj

Yamaha proprietary format audio files cannot be opened by any known DAW or editing tool. It's protected content.

That's the way it goes...

If wave type "Linear_16", you can open it in Audacity import RAW.

Hello there...

It is possible to reach Wave file from ppf.

All information is available in XML tags.

I wrote a simple program that is relevant to this topic.

Program can now read ppf data of 3rd person and export wave data.

But Yamaha's official ppf files are not yet open.

I don't think you will be successful.  Why do you want to do that anyway.  It would be stealing.  If you want the Yamaha sounds... buy a Yamaha keyboard with the sounds you want.

My goal is not to export Yamaha's sounds anyway.
my goal is to fix corrupted wave files in 3rd party PPFs
(loop point, late start point etc ...)

Even if I export Yamaha's sounds, it will not work ...

Because I already use Yamaha ...
