I am using a MacBook Pro and upgraded to 3.0 this week. It took ages to load first time so I removed loads of plug-ins from the list and that helped, but I found that after a few minutes (no matter the project) the line going along the time ruler goes out of time with the audio. It slows and glitches, so I can't visually follow where I am. Other controls become a bit sluggish too.
I have even tried abandoning it altogether and just returning to Maschine 2, but found that once a project has been loaded in Maschine 3, it fails - 2 just won't open it!
Does anybody have any ideas why this is happening or tips to stop it?
