The app itself won’t be scaled down. Even Logic Express was basically the same. It was missing some of the more hardcore plugins (Space Designer and Delay Designer, which are apple’s convolution reverb and delay) plus Mainstage, some of their audio converters and I think one of their dithering algorithms…and a few random plugins.
The biggest difference between Logic Express and Pro is that Pro can run on Avid HD and HD Accel hardware, so it can use TDM plugins and do zero-latency monitoring if you have the hardware to support it…which very few individuals ever do and even fewer have a real need for. Express couldn’t.
Ableton suite is $524 for a download version, and that’s the version comparable to Logic Pro. The biggest differences are in the workflows. Logic doesn’t have anything like Live’s session view, so if that’s important to you, Live is really the only option. For production, I think that matters a lot less than if you also want to do Live PA or DJing with it. If it were me, I’d consider buying both to use Live for performance and something else for production…but I’m weird and think that things take forever in Live.
Logic can also use better control surfaces than Live, and its automation makes more sense to me. YMMV.
One thing to consider is that Logic’s included instruments sound very good, but their UIs are completely unintelligible. I still don’t know how to use Ultrabeat or really any of its synths except for the 303 clone and EXS24…and even that’s weird. Some of them, I can’t even really look at and describe the signal routing…and while I’m not a great producer, that is saying something.
Live’s instruments look really boring, but their UIs are really straightforward.
If you’re going to be using 3rd party synths and drum machines, the it really doesn’t matter all that much.
FWIW, I think Pro Tools has the best bundled instruments. A few places are still selling Pro Tools 9 for like $500 and change. If your computer can run it, I’d recommend giving that serious consideration, but with it costing over twice as much as Logic and with Avid’s BS (it doesn’t run on every system and reacts very badly to OS updates) it’s probably not worth it unless you’re actually working with a studio or really prefer it. I do, but my laptop won’t run it. When/if I can afford to keep 2 computers, I’ll buy the other one using Avid’s certified systems list as a guide.
Considering price…I think Pro Tools wins hands down over Ableton if your computer can run it, if you’re okay with the 96-track limit, and if you’re okay staying an OS revision or two behind.
With Logic Pro costing $200…that’s a really cheap competitor.
