Ouch!
• When automating one channel in the Sonitus Delay manually - automation introduce clicks and pops.
• When automating one channel in the Valhalla delay it starts in stereo on replay.
• Same clicks and pops with the Manny delay when automating one channel.
So basically when you're creating a mono out to stereo | or | a longer time delay in on channel - theres bugs.
Yikes! It even exports with these sounds too.
