Remember, Audio Evolution 4 is available for MorphOS, AmigaOS4, and AROS.
And Audio Evolution 3 is still available for Classic Amigas.
What is the licensing scheme? I have AE3 for Classic, but would like to use AE4 with my MorphOS MacMini -- is there a concurrent license or will I purchase a new copy? As well, I am curious to know what MIDI interfaces are available for the MacMini to work with Audio Evolution.
