OK, I have uninstalled all vst3 plugins, total cleanup. Disabled every plushin and then removed in the preference panel any directory in audio. I recall that I am under W10. The pictures speak for themselves.
I made a comeback from the 12.5.6. I have the curve editor at the timeline.
So for me under W10, from the first version of the V14, the curve editor of the timeline no longer existed. I specify that each time I left the project created under V12.5.6 (import .DRP). Each time I left untitled project and the results were the same: no curve editor at the timeline but only at the clip level. For each version, I tested the ripple cut (CTRL + SHIFT + 'X') and it worked.
First consequence, except to be under MAC or LINUX (that I have not tested): no curve editor at the level of the timeline with the V14b1,2,3,4 and 5.
Second consequence: you can not blame Melda for anything.
Third consequence: I continue to do with Melda whatever you think and Davinci Resolve + VST3 seems to me reliable (at least with serious plugins)
