To create a song you only have to add tracks, choose the notes and the instruments. You will be able to play the music that you are creating to be able to check how it is working out, and thus fix the errors that you make. You will have access to a vast amount of instruments, like the piano, the guitar, percussion, flute and even choruses and special effects.
Aria Maestosa saves the composition in its own format, but it also offers you the possibility to export the result to a MIDI file. You will also be able to import files in this format to modify them and create new songs.
If you like music and you feel like composing songs, Aria Maestosa offers you access to any instrument.
