Sonar has great midi....second to none(including logic and cubase)
audio quality is up for grabs though some say its dull(even though it works in 32 bit floating as does cubase sx and logic) i personally haven't experienced it but i don't mix with it either i use an external analog mixer, but it has something NEITHER have which is ACID looping...so if u use acid a great deal throw it in the garbage cuz sonar can do that and much more...get Sonar 2 and now u have rewire so u can use such great programs as reason and rebirth
