Correct. What the PenDrive has (which I won't include) are the 42 new styles and 4 new sounds (or there about).

It will however include:-
* new audio drum loops to replace existing factory drum loops which will assist in resolving timing issues.
* over 650 additional drum loops with both STUDIO LIVE and PERFORMANCE LIVE DRUMS.
* over 30 new AJAMSONIC Sounds %%%
* new features in the OS (like GUITAR MODE ... etc)
* no more timing issues with styles... hence the new AUDIO DRUMS you will have to load/replace existing audio drums
* Better balance factory styles
* Arpeggio (both new which can be used by style engine or played with the lead voice),..

plus lots more.

%%% The new sounds are divided into groups/banks. To load ALL and use together, you will have to purchase the optional expanion memory chip. Without this purchase, you can only load 1 sound bank at a time. With this chip, all sounds can be loaded and accessed at once. It's up to you the customer to determin how you want to access these sounds. The full package (which also extends the warantee) will include this chip.
