@abdullah-a They are hard to find. These old versions of Music Studio were a feature reduced version of Emagic Logic 4 (Midi Studio) combined with a feature reduced version of Samplitude (Audio Studio). You can easily replace the old Audio Studio with the current version of Samplitude Music Studio. To replace Midi Studio you can search for a version of Emagic Logic 4 or Logic 5, which are much easier to find than Music Studio 2005 Deluxe or Music Studio 12 Deluxe. If you have an old Mac computer you can also try Emagic Logic 6 or Apple Logic 7.
