I have to honestly say that Im not satisfied with Music Studio. A lot of the midi instruments dont sound good, especially the piano sounds which are most important for me since Im a piano player. Other sounds that fall short are the church organ, bright electric piano, rock bass, and steel drum. Also, the string ensembles and orchestral flute sounds are too slow attack wise.
Other problems I feel are that the mixing capabilities arent amazing, especially the EQ effect. Plus, they dont give you chorus! I even partitioned for a chorus effect on their website about a year ago. Obviously I was ignored. Another problem is that you cant export your song as MP3! They give you other options (AAC, Wave, MIDI) but forgot to include the most important one.
This app is nice for jotting down musical ideas, but for professional musicians, skip it.
