Mike, if I understand your last post, you are trying to reduce the volume of a specific instrument that starts somewhere after the sequence has started. If the instrument has already been assigned to a part at the beginning of the sequence, panel write will help. If the instrument assignment for a part is changed from something else mid sequence (without using a panel memory change) and it is too loud at that point, you need to determine what measure the change takes place and do your editing at that point. See page 71 of your manual for that change. It is easiest though, if you can just use panel memory selection as the way of controling volume of each part.
