Calliope Midi Operating System for Auto Play

The Calliope Midi Operating System will play the Tangley Calliope and other music machines automatically.  Proper music midi files are loaded onto the SD memory card, which will provide plenty of music to operate the System.  “Phantom Power” supplies power to the hand held controller.  Therefore, the device does not need a battery.

The Calliope Midi Operating System has close to one hour of music loaded on the SD card.  Also, the card holds several thousand files for use. The Internet has endless free midi files available, for example.  Type 0 midi files are the type needed.  However, software can convert other midi files to the proper format.  Any computer can add midi files to the SD memory card.

The SD midi controller can record music from an electronic keyboard that has a midi out function.  As a result, you can record your own songs to play back on the Calliope anytime. Any song can play on the Calliope with this system together with the right resources and midi files.  So then there is a lot of versatility in thus gathering, creating, and adding midi files to this system.

Easy installation

The midi valves connect to the existing tracker bar tubing, which allows the midi player and music roll frame to be installed together. Therefore, you can switch from the Midi System to the music roll anytime if your instrument has both systems.
