Well, since Apple is reading this so carefully and so eagerly taking notes on what their loyal professional users want...
Here's a sampling of what they've "forgotten" to do over the last 3 years of Logic "Pro" development... I guess they were too busy caring about us composer types.
1 - MIDI plugin delay compensation
2 - fix multi-channel VI's so that they can respond to channelized volume/pan automation... You know, the way every other DAW can. (Please spare me the workarounds)
3 - Time stretching, beat-slicing comparable to that in PT, Cubase, Nuendo, Live, etc.
4 - a 'control room' section for headphone mixes, control room monitoring, and talk back. Dedicated controls instead of 'build your own' environment kludge kits.
5 - no more 'overload' messages. Hit play - This time it works! hit play again -- System unable to comply. Fun!
6 - Ping feature for outboard equipment, as noted above
7 - Wait For Note. Hasnt worked in, what, 5 years now?
8 - Fix broken support for hardware control surfaces, messed up in Leopard.
9 - cure the sliding outta sync bugs in the new comp/take-mode "feature".
10. Add "burn" to the "freeze" audio option. 'Burn' would be a one button method of committing all plugins to audio on a given track, or converting a soft-synth to audio without having to export, reload and realign.
11. Fix data/song management and file naming features that have been screwed up in L8, resulting in dozens of posts from confused and frustrated composers asking "where are my audio files?" "Why does Logic keep forgetting the audio destination folder?" "Why are all my files named the same?".
12. Larger font size option. For high resolution screens on a meter bridge, or more than a couple feet away, most of the type is verging on illegible.
13. Pop/Click/Stutter detection. I'd ask for prevention, but when is that gonna happen? At least, if Logic is truly PRO it would stop or send up an alert when the audio output is audibly compromised by digital glitches. Just the same way Final Cut Pro alerts you when there are dropped frames.
14. Customer Support. Respond to criticism, feedback, bug reports, and conflicts with 3rd party products. No pro app can completely ignore the pro user base.
So many more points I can't remember right now. It gets so tiring writing (and reading) these same complaints and feature requests again and again. If Apple truly cared, at least some of the things on this list might have appeared in the last 3 or 4 years. Nope. There are only two possibilities. 1) they don't care, or 2) they DO care, bu they're just too darn busy with something else 'more important' to do anything about it.
