As the Topic name says, the names of the MP3 themselfs tell you which
Pianos are used...i used a MIDI file for this for more accuracy.
The files are in WAVE format so no compression and stuff is applied.
It is completely loseless and high quality format:

I know the files would expire in a week but i dont know if everyone can use
Sound Cloud or other options, so i will reapload then again.

Here is a link to download them ALL at once in a Zip folder:
