I used Cubase for about 6 years, and then I moved on to Logic 5.5 on the PC - I think its amazing, and would never move back. We use logic 7 in one of the Ephexis studios, I have a love/hate relationship with it......
Good bits :
It does sound amazing, and the Space Designer reverb is quite unbelievebly good.... So are the other new effects. The ring shifter is a great rind modulator with many good features, and the little FM synth is also very cool......
The addition of an offline bounce is a great thing to see, no longer do u have to worry about whether or not you have enough CPU time to bounce down that wikid sound that keeps making the machine go wierd.
Bad Bits:
The interface has been 'Apple-e-fied', normally I love the interface that appears in all of the Apple 'Pro' range of software, but logic, somehow, they got wrong...... No longer can you hold control (or alt) and use the wheel to zoom in on the arranger window, instead you have to hold alt, and do the thing where u draw a square on the screen, which it zooms in on, and then alt+dble click to zoom out again - a small thing i know, but i love the wheel zoom in logic 5!
We've also found some very strange things going on with the EXS24, sometimes the samples are randomly transposed up a semitone or two, and then, after a couple of sessions working like that, they go back to normal again! really, really annoying, espcially with your working with a lot of percussion, or arppegios.
The 'External Synth' instrument at first, seems very cool - it allows you to run an external synth stright into an audio instrument object channel, and use the inserts on it in real time. Its great, until yopu have to bounce it down, make another channel for it, and replicate the FX once its recorded - so we now just create a standard audio object, and simply use the old fashioned record enable to enable VST FX, and adjust the delay on the track accordingly.
Also, we've found that stability is a bit of an issue. We're running a 2 x 2.5Ghz G5 machine, and i would say that it crahses at least twice a day, and, logic 7 still has no autosave feature! Shocking.
Another blow is the the Expose feature hasnt been propperly implemented - I was really looking forward to being able to see all of the FX settings, and instruments zoomed out and on one screen, but alas, all but the arrange and the mixer dissapear when you hit F9/F10 - shame!
I think in total it takes us about 30% more time to finish a project in logic 7 than it does in logic 5 - Which, with the increase in CPU power, I really wasnt expecting to happen.
Hopefully logic 7.2 will fix a few of these annoying things, and apple will have built up the guts to change the interface to make it feel a little less like a freeware app! Dont get me wrong, I love the logic 5 interface, but, it is a bit old!!
All in all, the projects that we make in logic 7 do sound a lot fuller than logic 5, mainly due to the reverb i think - but, Im quite happy with my Logic 5 / creamware scope combination - It sounds very analogue, and is reliable, and totaly adaptabel to the needs of any user.
Im sure i've got a lot more to say about the issue, but cant for the life of me remember any more points (chronic)!
I hope this helps!
