    synching tracks in GarageBand
    I have been creating mixes for my group. There are often 6 of us involved in this, creating vocal and instrumental tracks. Our general process is that one person makes a scratch video, singing and playing. The others then listen on headphones as we watch that video (we find a video makes it easier to try to match phrasing than just and audio file) and record our parts, usually on our iPhones. These files are then sent to me, and I create a mix. The first two songs I did worked perfectly. But lately I have encountered a big problem. In one case, the person who made the original video - on his iPad - also recorded his instrument (cuatro) separately on his phone. But when I try to put the two together, the separate cuatro track runs slower than the video, so they don't synch. On the other hand, I was able to record my banjo part on my iPhone and it synchs perfectly. On another song, I recorded the scratch video, and in this case the cuatro part that was sent me ran faster, as did another vocal harmony part. Any ideas?

    Re: synching tracks in GarageBand
    Hi - Depending on just how out-of-sync the tracks are, if they're only a little off one of these might be able to bring them back into sync.. - Designate one of your tracks [like a quantized drum track with tight timing] as a Groove Track, and set the problem track[s] to follow it - Open the Editor pane (E) and turn on Flex. Then you could - Try to Quantize the audio - Try to use Flex Markers to manually fix the timing: -- In the Editor pane turn Flex on -- Assuming the Region starts off in time and drifts out of time, grab the last note in the Region [which is assumedly not sitting on the correct beat] -- Drag it all the way forward, and then back to the correct beat This Apple support page talks about Flexing.. https://support.apple.com/kb/PH24952?locale=en_US&viewlocale=en_US and this video shows the use of Flex [though neither demonstrates exactly what I described above]..
