Tyros 2 and Korg Digital Piano

[aldus51]

Here I am again. Question: Is it possible to connect my Korg Digital Piano to the Tyros2 so that via audio cable I can
record digitally the piano and the Tyros on the Hard Disk recorder?
Does the Yamaha Tyros2 allow to record from external source like a digital piano?
I have read something on the manual but I would like someone of you to let me know better.
Thanks a lot as usual.
