Email from Matt @ Liquidsonics 01/23/21:
"It’s down to a combination of using an old channel declaration format in Juce, the order of the channel declaration (from memory it indicates mono to stereo first, stereo to stereo first would have been better, and how the host then uses this information for the default as the first in the list). Only Seventh Heaven uses this approach as its older, hence is the only affected plugin. I have a candidate fix, but a lot of testing is going to be needed to check it doesn’t break recall in some hosts. As it’s host dependent, it was certainly work putting that request into Ardour, I’m on the fence about whether the responsibility lies my end or the host end, but nevertheless, it’s on the radar for 2021."
Could you try if the `vst3rio` git branch fixes this?
git fetch git checkout -b vst3rio origin/vst3rio ./waf gtk2_ardour/ardev
(and later back: `git checkout master; ./waf`)
||This doesn't fix it, I'm afraid.|
||Fixed since Ardour 7.3 (with further improvements in 7.4)|
Hi, if fixed in 7.4 I'm afraid it appears broken again in v8.1.0
launching LX480 v4 on a Stereo bus results in mono inputs only.
Do you need screenshots?
