Instead of musicians handling the instrument, they simply move their hands in the air above. The position of the musician’s hands determines the sound produced.

Mapping<\/h2>\n
In the code above, the map<\/strong> function is used to map the Distance Phidget output to a reasonable frequency range.

Practice<\/h2>\n
<\/p>\n
    <\/p>\n
  1. Try modifying the maximum frequency to 10,000Hz instead of 1000Hz.<\/li>\n
    <\/p>\n
  2. Try switching from the SinOsc to one of the other oscillators like SawOsc or TriOsc. For more information, view the Sound Library API<\/a>.<\/li>\n
    <\/p>\n
  3. Add another Distance Phidget to port 5 on the VINT Hub. Use that sensor to control the volume of the sine object. Hint: modify the amp<\/strong> property.<\/li>\n
