I actually enjoyed using Logic when Emagic owned it. After Apple took it over, there was some advancements just as they did with Final Cut Pro in the late 1990's early 2000's. But Apple has now gone strictly 'pro-sumer', and I have finally had to give up on both FCP and Logic. Everything in the music industry right now is geared towards iPads, iPods, and interfacing with them. A million wannabes using the same app with the same tone with the same effects with the same everything else. Don't get me started!
Logic 9 was atrocious. I have never been a big ProTools guy as it isn't great with MIDI (it has been getting better over the years.) I used to love Opcode products especially Studio Vision Pro. I also loved Cakewalk Metro. For a heavy MIDI guy like me, that's the kind of program I need. I don't use VST or soft synths or samplers. I have a room full of keyboards and racks of old 80's and 90's hardware synths, samplers, and effects boxes. I still have quite a few analog pieces that are connected via CV/Gate to Midi boxes.
So currently, unless Logic 10 makes some sort of amazing turn-around, I am switching to ProTools for mastering and Sagantech Metro 7 for MIDI. Sagantech bought Cakewalk Metro and have updated it for OS X and modern use. It will work seamlessly with PT's and give me exceptional MIDI tools. I have used Macs for music since the early 1988 but I am seriously considering a switch to Windows 7. We'll see.
What is your use scenario?
