  • It only makes data. Tuesday, August 20, 13
  • It is a data horn. Tuesday, August 20, 13
  • The data that the EWI makes is MIDI. MIDI Tuesday, August 20, 13
  • A MIDI message looks like this: 144 60 80 Tuesday, August 20, 13
  • A MIDI message looks like this: 144 60 80 type Tuesday, August 20, 13
  • A MIDI message looks like this: 144 60 80 type data1 Tuesday, August 20, 13

  • MIDI The EWI sends MIDI messages to a synthesizer. Tuesday, August 20, 13
  • MIDI The synthesizer is just a program. It was free. (i.e., gratis) Tuesday, August 20, 13
  • MIDI The synthesizer sends sound to the speakers. SOUND Tuesday, August 20, 13
  • (demo) Tuesday, August 20, 13
  • You can send MIDI messages anywhere you like. Tuesday, August 20, 13
  • That is your right as a programmer. Tuesday, August 20, 13
  • MIDI I like to send MIDI messages to Processing... Tuesday, August 20, 13
  • MIDI ... and have Processing generates graphics. LIGHT Tuesday, August 20, 13

  • ChucK is a strongly timed language. “one second” is always the same amount of time. Tuesday, August 20, 13
  • Since rhythm is a function of time, ChucK is an excellent keeper of rhythm. Tuesday, August 20, 13
  • Programming rhythm means programming time itself. Tuesday, August 20, 13
  • (demo) Tuesday, August 20, 13
  • We can also send OSC messages from ChucK to Processing. OSC Tuesday, August 20, 13
  • ...and have Processing generate graphics. OSC LIGHT Tuesday, August 20, 13
  • We can generate the sound and the graphics at the same time. OSC LIGHT MIDI SOUND Tuesday, August 20, 13
