Nobody has anything to say about Apple Logic Pro? I'm incredulous. For $199.99, there's a LOT of stuff here. You have a pro-level DAW, with a full suite of effects including a convolution reverb, custom amps and roll-your-own guitar pedals. You get a sampler with gigabytes of content (EXS-24). You get a very nice jack-of-all-trades synth, ES-2. You get a physically modelled synth, electric piano and clav. There's a drum machine (Ultrabeat), and more loops than you'll want to sort through. There are only two things that I don't like about Logic. (1) It doesn't import General MIDI files well. (2) You don't have all the fun freeware VST instruments that are available for Windows.
The download queue's will probably be pretty slow for a few days. I remember upgrading Mainstage to v.2 was multi-gigabyte, counting the 'Additional Software" - which was well worth it! Does anyone know if Logic X requires OS 10.8.4 minimum, like Apple says (the new) Mainstage 3 does? I'm a big fan of Mainstage 2.2. But I'm still running 10.6.8 OS X because of compatibility with other apps I use occasionally. I just upgraded MOTU's Flagship DAW, Digital Performer, which gives you great control, less instruments for sure though.. . and now works on PC's too, to v. 8. So I need Logic even less. DP has had pitch correction for a long time, and it works great. Not automatically like Auto-Tune. You draw it in. There are plenty of ways to make music these days. Is one best? Maybe...but it depends on which feature set you use most, and what you've already built your workflow and rig around. Different for everyone. Enjoy.
