Audio Editor: Gain and Pan#416

Issue:
When using the gain or pan controls on a given track and releasing the drag state; the target value changes by one or two values (+/-). This makes it pretty difficult to set any intended target value for these controls. Further more the numerical UI lives user the user’s finger making it impossible to even see where you are dragging to.

Expected behavior:
Users should be able to clearly see the UI numbers when under a dragging state on these controls. Upon releasing the drag state of these controls at a target value, it should keep that target value.
