Hi
One reason (aside from history) for larger church & theatre organs having 3 or 4 (or occasionally more) manuals is to allow different sounds to be set up & used without having to manipulate the stops. It's very useful - even on organs that have lots of pistons to bring on pre-set combinations.
There are also a handful of pieces that just aren't playable as the composer intended on less than 3 manuals.
I've yet to play anything larger than a 5 manual.
Every Blessing
Tony
