Topic: Struggle during playback in logic pro x (+ babyface pro fs)

I have a problem in logic pro x while babyface is connected at the same time. When I press "play" to listen to the project, the audio is not fluent and starts to struggle/freeze.  The moment I disconnect the babyface, the problem disappears.
Here is a video uploaded to youtube that shows my problem  https://www.youtube.com/watch?v=UIoVs4O_y_A

Re: Struggle during playback in logic pro x (+ babyface pro fs)

Hi

What buffer size do you have set in Logic for the Babyface?
What is the activity window on top right showing?
I think at the end of the video the Logic app icon is jumping up and down in the dock. Is there an alert window appearing? If so, what does it tell?

And: it would be better to post this under „FireWire and USB series“ in this forum.
