Haven't tried that yet... although the MIDI stuff we added was in sync

Preferences all checkout.... still waiting to hear from Focusrite...

Hardware direct monitoring... as I have always done. This is the first time this problem has occurred and the only change I've made is upgrading to Mac OS 10.9.4 (Mavericks). I had heard that OS was having problems at the start but I thought they sorted it out in later versions. I have also submitted my query to Focusrite, thinking there must be a needed update to firmware and/or drivers. I have noted that my Saffire Monitor is 3.3, while a 3.4 update is available (and they note "tested with Mac OS 10.9").

Working in Logic Pro X (10.0.7) and recently upgraded to Mac OSX 10.9.4. Now noting a synching problem while overdubbing live drums. Despite the live performance being right in time, the playback is disturbingly out of sync. Overdubbing with my midi keyboard seems fine. Only seems to affect live performances. Could this be the interface (since the midi keyboard is direct into the laptop)? Anyone have this problem? More importantly, does anyone have the fix?
