Why am I getting no sound output when I try to use Halion 4.5 (all current updates installed) as a standalone app with my Oxygen88 midi keyboard as the input? This setup works fine using the keyboard through Cubase 7 (again all updates installed).
Audio outputs are set the same in both cases and I can see that the keyboard input is being recognised but there is no output. Am I missing something obvious? I confess that I find midi a bit of a black art at the best of times.
Any help/advice welcome
