I truly don´t think that "professionals" as in people who need 100% rock solid and repeatable performance are the main focus for the developers of Logic Pro. For example, professionals tend to not upgrade hardware so often, since once they have a solid setup they stay on that until it´s unpractical to use or breaks down= bad customer. Well paid person with a music interest on the side with limited time and knowledge about music production and who likes to get a new mbp every 2 or 3 years=good customer. These good customers won't go berserk over some small irregularities, they just want to make somewhat professional sounding music quick and easy. If you hope that Logic Pro ever will aim at primarily being "rock solid" and "pro", I think you are in vain. Sort of grim, but thats how I feel about it. There are some amazing stuff in LPX but I just don´t feel I can trust it, too much flakey stuff going on and I now work mainly with Cubase 7.5.1 after 10 years with Logic, and sure It has got it´s quirks, but it´s is really solid. I guess there is something with App developers that need to sell the actual app and not just having the app as a way to sell a certain hardware.
