If one could have automation curves for fx chains inside the phrase editor of the sampler, I think it would be exceptional…
That way, one would have a per sample automation for creating super rich instruments, as well as a per track automation for more global automation tasks.
I was just coming over to give the exact same suggestion.
In my opinion, if this gets too complicated to bring to life in Renoise 3, it would also be a really cool alternative to have atleast automation curves for the new instrument macros. This alone would decrease ones need for external synthesizers with automatable envelope curves and such greatly.
