Combis, Arps and Drum patterns

[studio99]

I'm trying to create a combi with a keyboard timbre and a drum pattern which uses an arp.
I'm trying to find a latin feel like bossa, beguine, etc.

The 2 Bossa options I found in the available arps didn't sound like any Bossa Nova I've ever heard. I tried the basic kit and the brush kit among others and all were way to aggressive.

I'm a newbie to the Kingom of Korg and not at all sure what I'm doing.

Are there other adjustments or different kits I should try?

As an alternative, Are there "aftermarket" combis or arps available that might cover other venues than those included?
Can you record your own arps and save them?

Thanks for any answers to these probably dumb questions!!
