Wine plugin midi fader mapping

hallo,

I have already posted the bug here.
https://tracker.ardour.org/view.php?id=9666

the (windows vst) wine plugin under linux works fine except for mapping the effect faders to midi faders.

the plugin faders are displayed in percent (0-100%). when i assign a midi controller to an effect parameter, the fader travel is only 1%.

Is there a workaround?
