Voice packs are loaded into the flash memory on Tyros. I don't think you will find them on the keyboard hard drive. They are usually stored in the YEM and held on the computer hard drive.
You are wrong.
it is stored somewhere, but we can´t acces that partition.
Why am I saying that?
I have a Genos and a Tyros 4.
Bot at booting are showing: loading flash...
The thing, I presume, is that all is compressed in a wavetable, that is loading at boot.
I did some digging with genos.
In C:\Users\USER\AppData\Local\YAMAHA\Expansion Manager\Packs\ it can be found every single pack installed in YEM, decoded in it´s way.
The locked one, has only a wave table. Open the .index and you will see that every sound has the waves in one wavetable
The unlocked, user, have multiple wavetables , for each sound.
Exemple
First text si from a locked pack:

the text is very long, I didn´t copy all...
se attached pictures.
Just like a locked pack, I presume, somewhere, there must be a wavetable, single, with all the flash data.
The thing I am working now, is to find a way, to copy from a single wave table, to extract, to multiple wavetables, and make them an unlocked pack.
But i still make tests.
