You can find a wide variety of applications that allow you to create music. Rosegarden is a audio/MIDI sequencer which can be used to create music for composers, students, and small studios.
Rosegarden has a window system that allows access to its various tools. You can see the arrangement of the song from the main area, but the score, matrix, and MIDI notes editors will appear in separate windows. This is just like it happens with other sequencers.
The application's elements are distributed in a way that makes Rosegarden easy to use. To move the interface around with ease, use the zoom function. You won't face any difficulties if you have worked with sequencers before.
Get Rosegarden free of charge and get a music sequencer that will inspire you.
