Hi there,
among other things, this new version addresses a couple of Profiler Stage related issues:
The periodic audio artefacts have been addressed
An issue related to MIDI THRU function has been fixed
S/PDIF slave mode has been added for Profile Stage
MIDI clock send works as expected on Profiler Stage
The updates can installed using Rig Manager 2.3.8 or higher. Alternatively you can download it here: https://www.kemper-amps.com/downloads
