Modus is an open source, cross-platform C++ library which allows you to handle music from code. This means that you can: * Manage interactive and adaptive music * Use some kind of algorithm to improvise * Represent visually (simulate) musical performances * Select in real time the instruments that are going to play a previously written song * Let the user take part on the performance through any type of interface, by playing an instrument, changing the tempo, choosing the instruments, designing the structure of the song, etc. * Define song structures with metric modulations, accelerandos and ritardandos * Write your own scores, which can then be assigned to instruments to be played * Play along with a pre-recorded song or represent the performance * Everything else that comes into your head
