There's a variety of different Digital Audio Workstations (DAW) that you can use. You don't have to use Finale; I would use this only to print out the music score (Export MIDI from DAW, Import MIDI in Finale, print score).
I myself have used a variety of DAWs such as Pro Tools, Reason, Apple Logic, and FL Studio. Out of all of those, I find that FL Studio is the best that works for me. All of my tracks are made with FL Studio (See my portfolio at http://www.soundclick.com/DestructionoftheSeal
). Alternatively you could use them together (i.e. Rewire Reason into FL Studio or other DAWs). It's really about preference here.
Software is not really the issue here; after all, it's not about what you have, but how you use it.
