I did a firmware upgrade to V3 just before I upgraded to V3 Midi driver, so I can’t tell you which one is causing the issue.
No amount of re-booting or other suggested fixes work.
Solution; I simply downgraded to V2.
TOOLS_for_URC_V210_Mac
- D/L old version and inside the zip file, run the 3 uninstallers for ALL three apps.
- Don’t install the TOOLS for UR-C V2.1.0
- Run Yamaha Steinberg USB Driver V2.1.2
- Have your control panel > security open and be ready to OK the installer.
- Reboot
- It works now.
