Hi Both,
The ZED-R16 has been discontinued for a few years now.
We continued to test and support the drivers for as long as possible, but unfortunately the chipset used for the firewire connection is no longer supported (at a lower level), meaning there will be no more updates beyond the latest (4.3.1 for Mac, 4.2.0 for Windows).
If it’s not possible to keep the working setup and the computer must be updated, then the best option would be something like the RME Digiface which has multiple ADAT ports.
Thanks,
Keith.
