Not really sure Hellboy but Reuben from the korg forum says its about 11mb of ram so still plently left for your drum loops. All i can say Hellboy is that that Steinway was my "go to piano" of choice for the last 10 months since i found it and i choose it even over and above the grandtouchx piano that came with the last great upgrade.
Find it and play it yourself and make up your own mind.
ps here is the link to the instructions to load just that sample !!http://www.korgforums.com/forum/phpBB2/viewtopic.php?t=23424&start=0
