Hi, I've got an Audigy 2 soundcard and Sonar 4. My computer is 2.1 GHz and I've got 1.5gb of RAM. I've been recently exploring MIDI, and the recording goes well, but when I play back the MIDI, it tends to skip certain notes (even though they appear on the piano roll). If I restart my computer or Sonar, it may or may not play back normally. It's very unstable. Any idea what this could be? Could it be my soundcard? Or my computer?

Thanks in advance,
Chris
