Halion Sonic 3 SE GM program change problem

HI All

I am trying to tell Halion Sonic 3 SE to use different sounds for particular program change numbers rather than the stock GM sounds. In the manual it says it can be done using the media bay by changing the pgm change in GMSound results column (with the “allow editing” tickbox enabled). I have tried it every which way but can’t get it to work. Any ideas out there as to what I might be doing wrong

Best Regards

Dave

PS. I’m putting it in this group as it concerns media bay as much as the plugin itself
