I am so happy for you that you did acquire the PAB Pro, despite your previous sonic concerns and admissions of doubt about the set and its developer's intentions. Bravo to you for taking the rather expensive plunge!
The words in your quotation show that you are in the process of learning a great lesson that one has to use his ears as well as his eyes to register a piece on the PAB. A lesser organist might slavishly register a piece only one way and miss the vast tonal resources this instrument has to offer.
In a different posting, someone asked about the registration used in a YouTube video of Bach's Wachet Auf. I was immediately able to identify the 1-1/3' mutation stop (by ear) in combination with an 8' and 4' flute-type stop because of many years' worth of experimenting/listening to stop combinations on several important instruments.
The good news is that your experimentation with the PAB in the privacy of your own home will add to your ability to register current and future pieces on this instrument as well as others.
Cheers,
Joe
