I am having the very same issue. I have checked the sample rates on my StudioLive 24.4.2, I used the very same sample rate on the Capture session and checked each one of the way files to ensure they are the same sample rate. Finally when I create a new song I used the same sample rate but it still plays at a faster speed. This is getting extremely frustraiting. I have an older MacBook Pro that I have been using for a very long time. I am using the version of Capture that works with my operating system 10.7 Lion. I also have the UC version that works with the very same operating system. Someone please help this is driving me crazy. I need to be able to record with it without the speed up when I import the files into Studio One 3 Professional. I have a new MacBook Pro but it has Sierra on it and if I have read correctly will not work with a StudioLive 24.4.2.
