My main workhorse for music is Finale. I use it mostly for transcribing and arranging music, along with some light sequencing. I like the autotranscription features which records what I play on a keyboard or a monophonic instrument by use of a microphone. The Garritan Personal Orchestra that it ships with is awesome. I might upload some samples after I'm done with finals. A big downside to it, however, is that the interface sucks. Oh... and it's expensive, but hey... I didn't pay for it. It's in the labs at school.
