I'm hoping there is going to be an update, as this little app creates the most amazingly useful percussion and synth sounds - it seems to just sound "right" when the .wav files are stuck into a mix. I've been able to use it to create a range of casio type blips, and more complex modulated electronic sounds that I dont think you could create with any other app or synth out there. It's based on the Korg electribe drum machine (the app looks like a screen shot), and as other reviewers have mentioned - the sound is *like* the electribe, but goes way beyond it. Who ever wrote this thing should be working for Korg to replace the sound engine of the electribe.
