Hello there. I have a Firestudio Lightpipe. I updated from High Sierra to Mojave, and I saw on this page (
https://www.presonus.com/products/FireStudio-Lightpipe/downloads) that I could work it out. But then, after rebooting and installing the Universal Control, I have a blank space at the Clock Source line on the software and on the interface, the light of the clock won't stop blinking (the firewire).
I tried to uninstall and reinstall, to change the firewire port (I checked the ports too), to turn it off and wait, but nothing worked.
Maybe it's not very stable on Mojave jet and it's better to get back to High Sierra?
Thank you for answering, I'm desperate!
