A new app was recently released called TonePad. It is very similar to Melodica only it isn't as polished. It is free though and has save and download features. It does have an ad though... http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=315980301&mt=8
yay that 1 screenshot really has me interested lol Looks like a lite brite machine from back in the 80's. Dev's gotta do a better job than that at putting out the screenshots.
I hate the download system. It generates a code which you give to your friend. The notes are way too small and constantly has me making mistakes. Also, the music is incredibly hard to hear without headphones. I will say this though, the musical notes themselves are really well done and have no distortion at all. I still prefer melodica but Tone board is still fun to mess around with
