Hello John
I envy those lucky people having GPO,but using my default soundfont I couldn´t stop listening ( volume almost to 10, the plaster almost coming down the walls )to a impressing piece of organ music.
Like Sherry,I love organ music ,organs also being one of the Kings of the Low regions.That is why bass players are always in awe watching and listening to good organists,I gues.
Keep them coming those organ concerto´s please.
Regards
Djim
