Script “MyOrgan-Hauptwerk” that I propose allows two things:

• If you have not open yet a score for your music with a virtual organ, it creates the special score for you.
  The score created, will be like the model “MyOrgan-Hauptwerk”, i.e. it will include the three standard staves of the organ (right hand, left hand and pedals), the rules to be able playing indifferently these staves with all the manuals of the organ (Great, Positive or Swell), the new "registration staff" with its rules  “Previous” and “Next” and 3 Midi curves pre-configured for the control of the boxes of expression.
  The staves instruments are especially selected and  preset on the right Midi channels. Do not click on  “remove useless instruments” nor “Solve the conflicts of the Midi channels ” you would cancel all the effects brought by this script.
  
• If a score is already opened and includes one, two or 3 staves for organ, from any soundbank, it modifies them to make them compatible with the virtual organ.
  As for the staves automatically created, the script replaces the instruments of the  organ staves, adds rules to these staves and inserts the famous registration  staff.
  There still, do not click on  “remove useless instruments” nor “resolve  conflicts of the Midi channels ” or do it before running the script.
