In Maestro VR's Creative Mode you can load midi files that will be detected by the virtual orchestra and you can conducting by manipulating the tempo.
In this video we can see a demonstration of how Maestro VR recognizes custom midi files.
For recognition, the midi file must have some minimal modifications: The trackname followed by the number of musicians you want on stage.
For example if you want there to be 3 clarinets, the clarinet track in the midi file should be called "Crarinet 3", if you want 1 clarinet: "Clarinet 1", and so on with the whole orchestra. There will be documentation with instructions on how to modify your midi files for conducting. To edit midi files you can use free software like Musescore or Crescendo, or paid software like Cubase or Logic.
Very soon we will open the early access, therefore the demo will no longer be available.
Soon more news.
