can I create new rhythms on boss br-800?

[kc2ine]

Hi,
just want to buy it but not sure if I can create new rhythms for arrangement or only built in are available. I don't want to use computer for this, just the boss. If yes is it only step editing or I can "play in" some rhythms?

thanks

Here's the online manual

Using BR-800 Rhythm Editor
By using “BR-800 Rhythm Editor” you can create
your own original patterns, arrangements, and drum
kits using a computer.
“BR-800 Rhythm Editor” is provided on the “BR-800
DVD-ROM.” For details on where to find “BR-800
Rhythm Editor,” refer to “ReadmeEN.txt” on the
“BR-800 DVD-ROM.”
* You won’t be able to create patterns or drum kits
using just the BR-800.
* You must install the USB driver before you connect
the BR-800 to your computer (p. 118).

thanks, that's bad the computer is required.
Are there any other digital recorders with built in more flexible and nonindependent drum machine?
