If you just need to translate your latest guitar riff into a piano sequencer and if you are like me that never really learned where all the notes are placed on the guitar neck this application makes it easy to convert the right notes to the keyboard. Guess that would be valid for any Piano player wanting to learn guitar too.
It is for free and the developer also makes another free application to help with scales and chords and if you have both applications installed they play nicely with each other.
