Bill (Bebop), or other E-80 owners with the version 2 upgrade....What is the limit of MP3's that the E-80 can recognize?

As an example the Sonic Cell max is 399..

The Juno Stage is 999...

Also , if the MP3 count is only limited to the size of the memory media..Can you use a 4 or 8 gig media...I am not sure the limit on the E-80..?
Another question, can the MP3's be indexed as we do with the SMF's, styles, and UPG's?

I need to know before I buy an E-80..and than resale it because I would be disappointed..
