iPadgebruikers are already able to enjoy this sequencer, but after the update the rather pixellized interface will replaced. Moreover, many more parameters of the instruments will fit on the screen, see the attached screenshot.
NanoStudio has mixer, a drum machine and synthesizer with excellent effects. The instruments are controlled by midi tracks.
It would be nice when the package would also include support for recording audio. Then this music studio for iPhone and iPad will be complete.
