I'm new in developing plugins with Sonicbirth.
I'm trying to do a simple gain with VU meter and run it on REAPER DAW. The only problem is that when I set the custom GUI on the plug in I see both the slider and the VU meter but I cannot make any change to the slider, otherwise if I leave the GUI to the host, REAPER only show me the slider (adjustable this time).
Where's the mistake????
