Recording using my Keyboard and random notes are missing during playback. Help!
I'm using a Edirol UM-1EX USB MIDI Interface (http://www.bulletsandbones.com/GB/Interfaces.html) to record from my keyboard into GarageBand. The problem is after I'm done recording, when I'm listening to the recorded track, GarageBand seems to skip some of the notes, it's like random short blank spots in the track. I don't understand why because when I'm playing/recording, I know I'm hitting all the notes. Is it the cable I'm using? Or my keyboard? Or GarageBand? The keyboard I'm using is Yamaha P155.
