Thanks for the feedback:)
What error do you have? "Open Device failed"??
I forget to mention that you must deselected midi device in your DAW on windows - because windows does not allow to share MIDI driver.
In other words go to your DAW preferences and select MIDI in and out to none(or select other midi device then this connected to KPA and used by the plugin.).
That's it ! Actually, since I use the 64 bits version of Windows 7, I put the 64 bit dll in my vst plugins folder and I got "Open Device failed" error ! Then I installed the 32 bit dll instead and no more error messages ! Now "get and save" seems ok but when I want to send it to Kpa, I can see the midi out activity led lightning on the fireface, which is ok, (it last a few seconds though while when I click "get and save" it's instantaneous), but my KEMPER doesn't react.
I'm gonna try to disable midi in and out in my DAW !
Thank you for the tip. I hope my explanations are not too confusing.
