problem with GrandOrgue

  • Hi, can you able to help me? I have a problem with GrandOrgue.
    I tried to install GrandOrgue on a notebook. This is very powerful computer HP EliteBook8460 Intel i7 GB hard drive SSD250 8GB RAM.
    I have a strange effect. Pedalboard plays normally, but manuals playing like a piano - as tight as it affects the sound is, as it is gently pressed key does not match the sound.
    To the situation was even more complicated, because the same goes If you start with the GO system - CD with Linux.
    Unfortunately, I ran out of ideas.
    Hauptwerk demo is functioning normally.
    Best Regards Jan Fecko
