Just loaded up new StudioLogic SL881 Studio midi controller. My Reason software isn't picking up correct midi signals, it only picks up short midi notes and isn't recognizing the length of the note. It sounds ok when being played but isn't recording properly. I am on windows 7. Done Reason software updates, all good. Other old cheap midi controller works fine. Been on loads of forums, most suggest hacking into operating system and changing registry keys which sounds dodgy to me. Any ideas?.
