Just got my first MacBook Pro and I'm trying to use GarageBand 11 to record a song.
I have recorded a keyboard track via MIDI without problem.
I'm now trying to record the drum track. Each time I do, the drum signal is dropped part way through the recording. It doesn't happen after a consistent number of measures but I never get more than 2 or 3 minutes of drum track and sometimes only a few seconds. When it happens the GarageBand timeline keeps going, but it records silence for the remainder of the track.
What am I doing wrong?
MacBook Pro (13-inch Mid 2012), OS X Mountain Lion (10.8.4)
