Oh, ok then! I'll just imagine I turned up at the last minute to play for something and found the pistons all blank and had to set up something in a hurry.
Sw 1: Echo Gamba, Voix Celeste
Sw 2: Flutes 8 & 4
Sw 3: Diapasons 8 & 4
Sw 4: Diapasons chorus to Mixture
Sw 5: As 4 plus Cornopean
Sw 6: Full Swell
Gt 1: Stopt Diapason
Gt 2: Open Diapason
Gt 3: Diapasons 8 & 4
Gt 4: Diapasons 8, 4, 2
Gt 5: Diapasons 8, 4, 2 plus Mixture and Double
Gt 6: As 5 plus Trumpet
As I tend to use "Gt and Pedal pistons combined" I would set the Pedal pistons to match the Great pistons. I would probably not put a crescendo on the General pistons, but reserve those for different "effects".
