I know this is an old post but, I'll answer it anyway. Finale and DP are two VERY different applications that serve two VERY different purposes. Finale is a notation program so, that's what it does... it NOTATES things extremely well (although, in my opinion it is difficult to use) and at a professional level. Digital Performer (DP) is an audio/MIDI sequencer and so it does that. It does not come with orchestral sounds in it. You would have to purchase a virtual instrument (i.e. Garritan) for that purpose. Usually, if you're a film composer, you would need both types of software but NOT necessarily THOSE exact brands (although DP has GREAT features that were specifically designed for film/tv composers). I should point out that I have both softwares and that I use both quite frequently. DP's notation abilities are very limited and Finale cannot replace a sequencer.

p.s.: FL Studio is a MIDI sequencer designed especially for elctronic-based music production.
