Music make you lose control!

  • This module consists of 4 keys, a play button, a record button, and LEDs indicating the progression of the module. Complete all 5 stages to disarm the module.
  • The 4 keys, when pressed, play 4 different notes, each using a different instrument. The keys can be pressed freely without consequence - input will only be recorded for a stage after the record button is pressed.
  • The play button will play one of the notes present, but with an instrument not present on the module. Use the instrument that plays this note and the color of the key that makes this note in the table below to obtain a letter.
