Comments and Reviews
Said about Rosegarden as an alternative
I am a long time Anvil user (windows). Rosegarden is more a cubase like program, but has the great midi features AnvilStudio has also, plus much more. So it is an alternative.
It is similar in that you can create your own music and audio files.
