This Max\/MSP patch takes a serial string in and converts it to a numeric value, then plays a frequency using the value.<\/p>\n

To use the patch, copy the text and paste it into a new max patch window.<\/p>\n

Thanks to David Mellis and Jamie Allen for the collaboration. These patches were written for a one-day Arduino workshop at NIME 07 hosted by the three of us. The Arduino program comes from the Arduino example files, by David Mellis.<\/p>\n
