Thanks to the Sonar Tutorial on this site I was finally able to understand how to get GPO Midi going. Below is one verse of Immortal, Invisible, Only Wise God.
What I did was to import an old Midi track where I used my old Roland JV1080 and then changed it to GPO. It is choppy - no "life" but a small success in that I was able to load it, change some parts, and add the GPO Ambience Reverb.
This simple import helped me to better understand how GPO works. Still having trouble using GPO as a VST - below is DXI.
A long way to go but thanks to all who helped me get off to a "snail's pace" start!
Trumpet, French Horn, Trombone, Tuba
Thanks again and God bless
