Im using trilogy on sonar 8 with a bass midi track from gp5 and it sounds absolutely retarded it only does one note and it plays random notes in between, everyone says trilogy is really good so i think im doing something wrong, i read somewhere that sometimes you needa change the notes an octave or two higher sometimes or something like that but I don't know how

can somebody tell me how to fix this thanks in advance
