Ever since upgrading to Mojave on my new iMac, Cubase artist 9 has been taking ages to start up. When it does, I have no sound coming through at all . I have to go to devices, switch to the computer’s sound card and then switch back to my Tascam US4x4 sound card - even after doing that it takes a few starts to ‘kick in’ and release the sound. What is going on? I want to upgrade to Pro 10 but if I’m struggling so much now, how can I guarantee that I’ll not struggle even more with the upgrade. Who can help with wise words of wisdom?
