So I set up a new song using Finale 2007b and GPO JABB, ya know? And I loaded up a set of instruments for a JAZZ type song. Only thing is, before I start, all the instruments sound just fine, but when I start playing back notes for a Jazz Fretted Bass line I lose the bottom octave of the available notes. When I go back to GPO and see what's up I find that the bottom octave is silent, and the rest of the notes have lost their tone. Instead of a nice full sounding bass I get a twangy type sound instead. I reload the instrument again and it sounds fine in GPO until I go back to Finale and try to play the line again. No sound in the bottom octave range again. Yes, I've tried fiddling with the velocity and modulation but to no avail. Same problem. Anyone run across this problem before? The electric guitar has the same problem. I have all the latest patches on for GPO and JABB and also for Finale 2007.
