Eddie...

It's easier if you save another copy of your SGU to remove the shots and holds. (Do a "Save As..." and call it {old song title}-NoHolds.SGU.. or something similar).

You can use "Search/Replace Chords" under the Edit menu to change most of them at once.... using
*... change to *

you have to also do
*m... to *m (to do all the minors... and so on...)

Generate what you need for mixing in a DAW.. and you still have your original...
