How does it work?

Keep in mind, Orchextra is an instrument. It is meant to be played and performed over the course of the show. It is not a playback device like a tape deck or CD player. The most basic way to play Orchextra is through the "Play" keys. By fingering the play keys, as you would a piano, at your desired tempo, you propel the song according to your individual interpretation. The process is analogous to conducting in the traditional sense; as you beat time, Orchextra responds. You can speed up and slow down to follow the performance, moreover, you can create deep rubato passages or taut accelerandos. 'Playing' is the essential way to breath life into Orchextra. So for starters, try using the play keys to perform some songs.
