Even though I'm not a real huge fan of Korg.., kbrkr is right. The stock piano on the Triton might not be considered up to par with others, but you'll get much better quality painos with the expansion boards... Roland did this with the XP series.. The XP-60/80 were good boards, and came with decent stock sounds, but the real power of that keyboard was in the expansion cards. Honestly I don't think you should have to buy an expansion card to get a better piano sound on any synth... Their best piano patch should be included with the keyboards voice set...
