For some reason I read use the down arrow and select and item, it’s the same issue nonetheless.
Diva doesn’t prioritize input focus when opened in Renoise, might be how it handles being opened in a popup instead of its own editor window like in Reaper or Logic.
Thanks all, i have an answer from u-he support, i paste with their authorisation a part of the answer :
“we recently found a workaround for this, so in the next update it won’t be necessary anymore to activate that keyboard option.”
“we currently cannot say when the next round of updates will be available. We are currently working hard on a lot of different areas, so it will take a couple of months until we are able to post some new betas or updates.”
This one was recently fixed in the latest Diva update (also Filterscape 1.5). U-He is rolling out updates for most of their plugins sooner or later, which will finally fix this issue.
