Does this still stand as the best? It seems to be the only dedicated piano VST that I can find on the app store, but others have talked about getting an iOS VST host then upload a VST to the device. However, most of these reviews are about two years old.
I've done a little web searching and a lot of folks have praised Ravenscroft 275 as the best available. I should soon be receiving my Piano de Voyage and in the spirit of keeping it small and light for travel, was thinking the my iPhone would be a good choice to host the VST.
