Except for the piano and a few other percussion instruments the volume is controlled by the mod wheel. Metro's Graphic editor allows you to manipulate the velocity of the notes which controlls the volume. With GPO the velocity and the volume are controled by two different midi controlers (I guess)so you can't change note volume with the velocity tool except for the percussion instruments. Has GPO thrown a monkee wrench into standard midi sequencing by doing this. There is a option to reset to STD. CC#7/CC#10 for volume and pan but it didn't seem to make a difference. I can't post on their forum site for some reason and I have emailed as to why but I have not gotten a reply.
Any Ideas?
