  a formula for converting MIDI note numbers (0-127) to pitches. This sketch
  reduces that to the notes 21 - 108, which are the 88 keys found on a piano:
 
- frequency = 440 * ((noteNumber - 69) / 12.0)^2
+ frequency = 440 * 2^((noteNumber - 69) / 12.0)
 
  You can see this applied in the code below.
