I suppose it’s not possible because I haven’t found any way in the manual, but I’ll ask anyway.
Is it possible to edit automation data in the Key Editor?
I found much better to draw and move line points as it’s done in the automation lane, rather than drawing blocky data in the controller lane. Defining different curves between points in the automation would also be nice (just like the envelopes in Halion 4). Which reminds me that it also would be nice to have points and curves in the Note Expression editor. Currently is very difficult to draw a nice expression curve with the mouse.
If not possible, I would like to see this feature implemented in the future.
