PSP homebrew developer eculewatt (creator of the Modded PSP Flash Player) dropped by the QJ.Net Forums earlier to announce the release of Piano Station Portable 1.0.

This application is a piano player, and is mapped to the PSP's button controls. User can play seven basic keys: A,B,C,D,E,F, and G.

eculewatt also noted that an updated version of Piano Station Portable is being readied, and will hopefully carry better features. Guys interested in picking up more information, or demonstrating any songs they've played on this app, can opt to drop by eculewatt's release thread over at QJ's PSP Development Forums.
