ACCS The Miracle Piano Teaching System Nintendo

The Miracle Piano Teaching System consists of a keyboard, connecting cables, power supply, soft foot pedals, and software. The software comes either on 3.5" floppy disks for personal computers or on cartridges for video game consoles. After the supplied MIDI keyboard is connected to a console or computer and the included software is loaded, a user follows the on-screen notes. Its marketed value is as a tool to teach users to play the piano. It provides hundreds of lessons, and was advertised as the perfect adjunct to formal lessons. It was sold for US$500 and had low sales, in part due to its high price.

It was released in the United States and in multiple regions of Europe. Some of the NES Miracle keyboards were later converted for PC use and the Nintendo Seal of Quality on these boards was covered up with a piece of plastic.

With the exception of the metronome that is used in the Miracle system's lessons, the Miracle system does not ever generate sounds through the video game console hardware. All MIDI information from the console is converted into audio by the instrument's built-in ROM and played through the instrument's stereo speakers, allowing the keyboard to be used independently of the console.
