In a word.... No. The main purpose of the hyper editor is to create stepped beat/division based MIDI control changes. You could move the data from region to track in the consolidated arrange page and then curve it!
hey guys. just wanna to add that this can be achieved using the transformer as well.
select all the data u want to change (holding shift + click)
under operations, set the data byte 2 to "expon." (which i assume is exponential).
Now changing this figure will allow u to change the steps in a concave manner or vice versa. Then just hit "operate only"
