I’ve been encountering an unusual problem with my Minitaur set up. This problem began occurring some length of time after upgrading firmware and driver configuration and I initially thought of it as a user error problem, though perhaps it still is in some respect. 
So here is what I’m dealing with: Saving panel settings to a new preset results in a non-operable preset, every time for my Minitaur.
Test steps:
Turn on Minitaur and open editor
Save the Panel settings state as a preset
Change to a known good preset
Change to freshly created panel setting preset
Observe no change in the sound from known good to panel setting presets
I’ve tired these steps with and without Cubase being open and getting the same result.
Set up details:
Editor 3.1 64
Firmware v2.1.9
Driver 3.30.0
Cubase 8.5
Windows 10 64
