I know to hold "ctrl" for a slower scrolling. But can I type in the exact # I want for a velocity envelope? Thanks Guys.
Right click on the node point and select "set to..."
In addition, it doesn't look like you have the min/max button enabled for your track. If you enable that button and max the track you'll find it easier to drag envelopes to a more precise value and then restore the track height with another click. Works best when you switch to a window layout with a smaller preview box.
Click the "three dots" button to be able to edit visible button set.
