That looks right actually,
Just to check, I think you need the external ‘mrpeach’ to run this - have you got that already?. ORAC is great, but the documentation is a bit… ‘distributed’ I found 
@thetechnobear has added just the externals it needs to github. Or you can use the ‘help/find externals’ function in Pd.
