As discussed below, I had to reduce zoom from 125% to 100%

Hi does anyone else have this bug...I'm on Platinum Kingston build, have raised a support ticket...
 
The midi event filter has a bug (using latest Kingston build).
 
When I try to adjust the sliders for example on the 'Notes' filter the slider does not move smoothly between C0 and G10 and often goes straight to the max or min...this happens on all the other sliders too.
 
Workaround is to click on the value box and just type it in.

 
I have no idea why you are experiencing this.  I can't get the Event filter sliders to misbehave on my system.
 
Is operation of controls smooth in other plugins ?  Is your mouse at all erratic ?
 

There's a post about it  and another one - related to setting the text enlargement factor. 125% works, but not larger.

Thanks bvideo i'll try it.
 
PaulP...it's only the sliders in the MEF.
