I am in the middle of creating "Somewhere Over The Rainbow" for my grandparents birthday (wish they just liked socks). I have copied the sheet music into my sequencer (Cakewalk Music Creator Pro V2). I know there are a few steps that should be taken to humanize a MIDI map, for example, Altering Velocity, Altering Note On Time and Altering Note Off Time. But the problem is I have no idea how the numbers 0 to 127 relate the real life playing has anyone get any pointers. Its a piano part if that helps anyone. Thanks. Peter.
