It's an upright(AKA House)piano and you can hear the string release. Common all over. Nothing special about the sample, no detectable effects or anything. Don't expect to get some pristine grand piano sound and use some effects(I swear to god on every "How do I do this" thread there is some jackass who says something like 'sounds like a piano with some chorus and delay, maybe a lil compression.') and turn it into an upright piano, it's not going to happen.
Best bet is that many keyboards, modules and sampling plugins have decent sampled upright's. Get access to one or record a real one. If that isn't an option then I don't know what to tell you, to get the sound you have to get the instrument.
