Average Rating

Drawdio is a very simple musical synthesizer that uses the conductive properties of pencil graphite to create different sounds. The result is a fun toy that lets you draw musical instruments on any piece of paper.

No more blah blah, watch this videoto get what it's all about. Have fun!
