Thank you most sincerely for your replies, gentlemen, which were enormously helpful. My apologies for the delay in responding, but I have been carefully working through your comments.
@DerekA
Enormous thanks for demystifying some of the tacit (or perhaps, tacet) features of the manual, which now make much more sense to me. Also, your comment about the rotary switch having an alias in the VARI button gave me a real facepalm moment....
@andyg
Thank you for all your helpful information. In spite of being a pipe organist for decades (sadly, the arthritis in my fingers has finally meant that I have had to give up the pipe organ and piano, which is why I now have to use a keyboard with a lighter touch so have taken up the S970) I have never played a Hammond organ. But the footages and the associated numbers make perfect sense to me, of course, although when you said "plus 4' percussion" I wasn't sure what you meant?
But your treats keep on coming. Thank you for the magic numbers (68 8600 000 and 00 7654 321), and also for the invaluable information about Dual Rotor Bright. Rather than stabbing at buttons at the relevant points in the music, I had already standardised on always using registrations with a dedicated foot switch for changing them, so your suggestion is a perfect fit. Your comment about Organ Ballad being intended for WSOP gave me yet another facepalm moment: I suppose it's obvious when you listen to it, but <sigh> with so much to discover about the S970 I hadn't made the connection yet. Mind you, it was only last week that I finally worked out what MOR means, so obviously I have a lot of catching up to do....
So I'm left with just two questions, and would be grateful for any further advice that you might be kind enough to offer:
- What did you mean by "plus 4' percussion"?
- Is there, by any chance, some information available anywhere on typical uses for Hammond's "magic numbers" (68 8600 000 and so on)? Other than in your head, that is....
When I started working on WSOP I had no idea just how much I would be able to learn — with your help.
With thanks and every good wish,
Brian
