GarageBand is not playing any sounds

 

This can happen when the MIDI Bluetooth connection gets confused between the two applications. Follow these steps below to get sounds playing:

  1. Close both GarageBand and Sensorware applications
  2. Open the Sensorware application
  3. Make sure all sensors are connected
  4. Open GarageBand
  5. It's usually a good idea to go to "Advanced" settings within GarageBand and select "Run in background" and also "Use with music apps".
