What is Expansion Packs

A Yamaha Expansion Pack is a package which adds more content to the keyboard:
- Voices
- Styles (optional)

Voices and styles are merged into a file, having a "yep" or "ppi" extension.

Some expansion packs contain Registrations and/or MultiPads. These data are not included in the "yep/ppi" file.

Where to get

Expansion Packs can be obtained from Yamaha Shop at http://www.yamaha.com.

Besides the Expansion Packs for sale, some free Expansion Packs can be found at Free Expansion Packs

Interchangeability

Expansion Packs for Tyros 4, Tyros 5, PSR S970, PSR S770 and PSR S670 is a new common format. File extension "ppi".

Expansion Packs for the PSR A2000, PSR S750 and PSR S950 have the same format. File extension "yep".

Expansion Packs for PSR S650 is another format. File extension "yep".

The size of Expansion Packs is limited by the keyboards storing capacity.

Installation

The "ppi"/"yep" file is the installation file of the pack which goes into the keyboard.

Only one "ppi"/"yep" file can be installed in a keyboard at the same time.

However more "ppi"/"yep" files can be merged into one "ppi" file. See more below!
