Is there a way to mark an entire block and to make the volume slide from the first note’s volume to the last note’s volume ?
I know there is a volume slide effect, but I just want to let Renoise set the volume values automatically between the first and last selected note.
Such a thing was possible in Impulse Tracker.

It’s in advanced edit:
http://tutorials.renoise.com/?n=Renoise.Re…iseAdvancedEdit
(scroll down and look at “Vol, Pan, and Effectvalues”)
There’s also shortcuts for this. Look around in the tutorials and you’ll find them. 
you can do it with ctrl+i. just enter first&last notes volume, select them and then press ctrl+i (interpolate).
