I am using Dorico 5.1 with Halion. I cannot unmute both channels – I can unmute one, but when I try to unmute the second, the first becomes muted again. Here is a screen recording (sorry it’s so jerky, but I’m using Windows’ snipping tool) : https://youtu.be/SQPGwkzzoxs
I have seen complaints about this behavior with other VSTs, but I still have not seen a solution.
Thanks.
