I have been using Digital Performer since version 3. I changed to Logic last year because of the arrange window and all the many millions of little Apple friendly things, such as click for Loop, and bounce midi and audio files simultaneously and to multiple formats such as aif and mp3 in one swoop. There are too many of these little things to mention but they all simply make the experience so much easier and fun.
When I first started with Logic, I spent too long trying to figure out how the heck you set it up for external midi keyboards and how the midi routing works. Tutorials, manuals, posts... it was almost like it was a taboo subject. And now I know why. heh. Somebody was on drugs when they created that part and they don't want to talk about it !


However, one day I sat back and pondered... Maybe Apple doesn't really want you to use external midi keyboards ! While that is possibly not true, I spent an entire night just using Logic's soft synths as well as other ones I had. Well this was certainly a horse of a different color. What a breeze ! And now all of the Logic conveniences really made the experience a dream come true. Click new track, select plug-in, done. So I decided Fine. I will change my studio to accommodate Logic. And so I did. I'm glad I did but I wouldn't have if Logic hadn't pushed me in that direction. I still need one master keyboard and will probably get an M3 or M4.
The other day I mentioned something about the midi routing in Logic to a friend and found this in part of a post. It describes some differences between DP and Logic. I think it is a fair assessment although I hated chunks in DP and I do most of my (light) audio editing right in the Logic arrange window so far. I thought it might be helpful or interesting to someone else so here it is.

Logic:
- Performance, it is much more efficient.
- Freezing and bouncing of tracks, again, more efficient. You do not have to record down all your virtual instruments to bounce out a project like you do in DP.
- Better built in synths and effects. With the exception of Pattern Gate which there is no replacement in Logic. Most people probably don't use this that much, but I did, and I miss it.
- MIDI Editing. Hands down I like this WAY better than DP.
- Multiple instrument in and MIDI routing in Logic is definitely not as easy as it is in DP, and I find this to be something that needs serious attention, however, I have written Apple about it with some suggestions on fixing it. What I mean here is using more than one keyboard at one time in Logic is not as simple as DP.
- Comp feature is absolutely awesome. One of the best features
DP:
- Audio editing is superior. I really dislike editing audio in Logic compared to DP. If you plan to use the DAW more like a recorder, you'll be better off with DP.
- Scoring. DP allows for multiple songs (called chunks) to be in one file that you can arrange in a sequence. This makes it VERY nice for moving things around when the video editor starts moving things around.
- Virtual Racks. You can load up instruments to be used across several songs. Again, for scoring this is VERY nice.
- Midi routing. It is SO easy to use multiple input controllers it's not even funny. If you plan on using 2 or more keyboards at the same time, I cannot stress how well this is done in DP.
- Midi ARP. Midi track have plugins just like audio tracks. Using an ARP is so easy and doesn't require the crazy hookups in the environment like it does in Logic.
This is a quick list off the top of my head. I do more midi than anything else, so for me, Logic wins right now hands down. It's fast, it's efficient, and the comping is amazing for vocal work.
I still use DP when I am tracking live instruments (guitar, bass, jam sessions) because the audio editing for me just makes more sense. That said, I still bring it over to Logic for everything else. They are both AMAZING programs, so I hope some of this insight will help. Everyone will tell you, it really comes down to what you need.
