It would be great if underneath each parameter knob there were a small window displaying the current value of that knob. It seems that the whole point of lining the knobs up at the top of the window is to make testing easier by eliminating the need to have any one parameter tab open in order to control the event. But there’s no point in testing by using the knobs if you can’t see what value you’re setting the parameters to.
Believe it or not, this is actually an outstanding bug: Parameter knobs are supposed to have the same kinds of editable value displays as the knobs that appear in other parts of the interface. Fixing this issue isn’t our highest priority just yet, but we’ll get there eventually.
