Re: help Logic 9

I still do a lot of audio in Cubase as its a lot quicker than using Logic (8 at least)

If its the same in 9 as 8, click on the file you want to reverse so its highlighted.
In the bar at near the top (Edit, Track etc.) click ‘Audio’ and ‘Convert regions to new audio file’
You may need to change the name.
Then you can reverse just this section.

Crossfade curve can be adjusted in (top left of arrange window) Preferences > Audio > General.

Not sure about the keyboard.
