Manage music remotely

Music is stored in the Apollo III as MIDI files. These files are stored in a PC compatible file structure (Windows and IOS). File exchange is possible by LAN (SFTP, Filezilla) or by standard USB storage media. Thus, the carillonneur can remotely manage the automatic music played on his carillon.

A MIDI file may be recorded from a MIDI keyboard (e.g. baton carillon practice keyboard) or generated by means of a MIDI software package in a computer.
