I am having a recurring problem on a project I need to finish ASAP. I
have a piano part recorded in audio. I get an audio artifact playing
just *before* the piano audio region.
If the noise is in the audio file, then cut the audio in the arrange page so as to lose that noise. I am not sure how the erase tool fits into this. I would just zoom the arrange window really big, and loop the first bar or two, look for some spikes move the start of the loop region so it starts from a clean place with no noise, then cut the audio file there.
If you do that, and the noise persists, it can be the "buffer flush" noise that I was talking about the other day. In that case, try starting your playback a bar or two earlier than where actual sound takes place in your song. That will allow any remaining audio in the audio buffer to be played out, and get quiet again before your real music starts. [ I have no idea how it actually works, but I think in order to have smooth cycle loops, Logic needs to store the beginning of the loop sound in memory, so when it gets to the end of a loop, its ready to play the start smoothly. So maybe if you turn off "smooth cycling" this might get rid of the noise.] I would take for granted that you need to pre-roll and post-roll any final project, then trim as necessary. Remember reverb tails and long sustaining notes shouldn't be cut off abruptly.
If those two things don't work, then try muting the entire track and seeing if you hear the noise when you play. Maybe its coming from other track you think is muted, or some midi instrument. If you hear nothing, then do it the other way - solo that track.
There must be an answer. And it won't take long to find.
