Synchro Arts have announced that M1 beta testing is complete and have released Apple M1 machines native support for all of their current products – Revoice Pro 4, VocAlign Ultra and VocAlign Project 5.
Note On ARA Support In Logic Pro:
If you use Logic Pro, ARA plug-ins are not currently supported natively on Apple Silicon and will cause Logic to crash. Apple will be rectifying this issue in future versions of macOS and Logic Pro. If you want to run Synchro Arts products in ARA mode on M1 macs you will need to run Logic in Rosetta mode. Alternatively, non-ARA versions can be used natively on Apple Silicon.
