Greetings. I have been a user of garageband for 2 years and have recently upgraded to Logic 9 express. While the program has some obvious advantages, it seems to have a problem that no music program should EVER have. My problem is controlling the volume levels of a single instrument without having it glitch or conflict with whatever it seems it "wants" to do. I'm new to this program and I've only been using the hyper editor for my volume changes, but I find Logic Express 9 unusable if I say, set the volume on a whole note at 4 db, then while it's holding the note, it will shift to 6 db and then back to 4 db and continue this unpleasant cycle until the note ends. Even after that's done, it might gradually decrease from 4 to 0 without receiving any instruction to do so. Is there any way to get rid of this glitch, or even better, another way to edit volume?
