The increment of the pitch changes depends on how you set up the midi controller in albeton. In 5 when you assign a controller you can set the high and low value, so can set it over a 5 BPM range and the increment will be small, or you can set over a larger BPM range and the increment will be large. It is possible to do the same thing in 4 but the set up is a little different. I use this function over a 5 BPM range, assigned to one of the knobs on my Xone 92, and the increment is about .1 BPM. It works well when you want to adjust the tempo of ableton to a record.
