Awesome! Benyamin5 - United States
Let's you totally customize your chord voicings. Layout is absolutely brilliant. I've never been this excited about an iPhone music app. Or probably any app for that matter.

Exploratorium
PianoStudio is the first piano app for the iPhone and iPod touch that helps you explore musical ideas, learn songs, and write your own tunes wherever you might be.
Play music
Listen, the iPhone isn't a piano. So why run an app that insists you finger chords on a little glass screen? PianoStudio makes it easy to assign notes, chords, even full phrases onto nice, easy to hit buttons. Play music, don't play around!
Sharing
PianoStudio supports AudioCopy, making it easy to export your piano songs into compatible apps (iShred, GuitarStudio, BeatStudio and others). You can easily share an MP3 of your creation from right within PianoStudio.
A world of music
Looking for inspiration or want to try your composition out on others? PianoStudio features WorldPlay with shared songs from around the world. Sit back and listen or download songs and learn.
