Maybe it's the trackball, dunno, works OK here.
How does it actually sound?
Maybe the video card is just displaying the sliders poorly (?)
the actual written MIDI should be pretty smooth though.

Keep in mind, they won't all be in line (unless they all started that way) as they fade, because 1 track may be fading from 80% to zero and another starting at 100% volume and fading to zero over the same time span.


I do not work here, but the benefits are still awesome
