I was hoping for a bit of feedback from anybody who downloaded the Demo.
Unfortunatelly, I can't help you with that. I'm not your target customer.<img src="smileys/smiley1.gif" border="0" align="middle" />
When I see someone doing beatboxing, I can say it's impressive, but I'm not much into it. I can only tell you, I haven't found any major bugs, flaws while trying the demo.
