This is IMHO one of the best pianos around, I am referring to the Steinway Piano preset, even better than many commercial instruments or gigabyte-sized sample libraries. I usually add some external EQ for a more natural sound though. I'd have rated it 5/5 if it were not for some minor issues: -The parameters *apparently* cannot be stored (this at least happens with Reaper, I could not try with other DAWs). If I need to modify something from the defaults (tuning in my case) I have to set it by hand everytime I reload my project. This is very annoying (I'm trying to contact the author to understand whether it is an actual bug or a problem with Reaper) -The GUI panel takes some good seconds to open, something I never experienced with any other VST -The A and A#2 (Steinway Piano) have a very subtle hissing noise at beginning which in piano solos can be heard and slightly annoying (something resonating while recording, possibly the samples were not fitlered/cleared) Despite all, it's definitely a *great* piano considering it's free !! One of the pianos I like to play the most. Good work. I would like to see the issues I listed above fixed someday though.Read more
