JJ OS1 stuffed with sample?

i never actually used OS1. now i happened to boot it to check out, changed from XL by pressing TAP. then booted it again, this time NO CF card inserted. i have NO internal HD. so i booted my MPC and loaded absolutely nothing in it. and there it was: a sample called RS_CPotHiHat in the memory! is this something that is included in the OS1 bin??? i never heard about such. have i missed something, or is this some sort of ghost in my MPC ...?

strange!

that'll be the autoloading of the internal flash memory - user must have saved stuff there once!

about 5mb's in there somewhere right? helpful for shops, they used that space for demo's n such.

oh yea, in the akai OS, right? but still weird.

JJ OS1 (and the free version) can autoload from the internal memory, just like the Akai OS's. So how is that sample, anything incredible?
