Tried to make a simple looping note, pressed play and it hung my tab with an 'unresponsive script'. Nice concept UI, but couldn't make any sound.<p>The idea of the 'puzzle pieces' to show where to slot in components is very interesting though. Maybe, although my pieces stuck together properly, it was syntactically invalid? I would think that with the design such a system would prevent invalid programs from ever happening; quite an achievement IMHO.<p>Now if only I could get it to make some sound...
