Hi My Problem is: I use this Libary called Sonivox Symphonic Orchestra with Kontact 4 and somehow the new Mac is always stopping-loading and than it goes on! Terrible to record! Have anybody a Tip to get my System faster and more fluent? Peace&Respect Alex

Hi Alex Welcome to the forums. We'll need more details to be able to help: - Version of OSX and Logic. - Do you have the latest updates for Kontakt 4? - What is your audio interface? - What I/O Buffer Size settings do you have in Logic? Logic Pro > Preferences > Audio [Devices] - Do you have any other applications open while recording? Thanks Rounik
