The version on Aminet says it's 2.0 but comes up as 37.14 when you open Midi Preferences, so I'm guessing we have the same version.
Changed the Serial Prefs to match yours with no change.
I think there may be a problem with my Midi interface (Datel Midi Master). I might have to get a different one
Got it working! I had 'True Roland MT-32' enabled in the global settings as I also have an MT32 connected.
Disabled that option in the 'Edit Game' settings and it's fine :-)
