Hi, I just got a problem today with my fader tool on a audio track...It worked once when I used it with speed up....Now I want to put a speed down on another track and it does not work.Fader tool is not working...My audio tracks are only coming on one track too.I have four audio tracks and they end up on the same track.I am running Mac intel 10.10.1.It all started today.My 01W/fd korg is fine with other plugins.

So you can make speed up fades on your audio regions, but not speed downs? Is it project specific or does it happen in any Logic project. Try create a new Logic project, record in an audio region and see if it works on a new audio region.
