I have updated my logic Pro to Version 10.4.1. I am having sillier problems, when i try to record vocals its mixing channels at time and also when i add a new track. the vocals are recoding with some form of effect on it and its been driving me crazy. first i thought it was my Mic, then i used another one. i then though out could be my Apollo 8 interface, i then changed that to a Apollo Twin duo, the problem is still there.
Then i try record vocals on a old track, then it seems to be fine, however when i tried adding a new track i was having the same problem again.
I then spoke to a friend of mine who is still running Logic Version 10.3 and he seems to be doing fine.
