Hi,
I think I found a bug with the track and buss groups.
I created a new group, and disabled the “Gain” feature. The “Relative” checkbox then gets disabled as well, so one would assume the feature is disabled now as well. But resetting its value via Shift+Click still applies relative gain changes to all group assigned channels. It even changes the fader value when the group is disabled. I think that is not intended…
Best, Vivien
Edit:
Ardour 8.12.0
“Sonora Portraits”
(rev 8.12)
Intel 64-bit
running on NixOs, But I think it would apply on other OS as well?
