Then it should only work once, when activated and default to HW normal the next time things are booted.
The problem would still exist, for 1, the organ computer runs 24/7. And while one hymn may be an organ solo where the organist chooses to "bump" the pitch up a couple semi tones. Immediately followed by an organ/piano duet where the organ pitch should have been reset to the standard A 440 pitch.
While maybe not a very sophisticated solution, I'm thinking in terms of
the switch controlling (remote) small Double pole relays, one per switch position. One pole of each relay controlling transposer ckt, while other pole would operate an indicator. The relay relating to the
home (no transposition) switch position would
not turn on the indicator. A little klutzy "solution ?" sort of.
Another non standard control function - each manual has the related pistons for the c/a etc, under the manual. But in addition there are 8ft intermanual lighted coupler pistons. So any coupler piston from the Swell manual is lit with a green LED (in the piston). Any coupler piston from the Choir manual is lit with a blue LED. Any manual to pedal coupler is lit with a yellow LED. This kinda solves the problem of which manual is coupled as these coupler piston are next to each other. Their function is duplicated in the coupler rail above the Swell manual using the same *"color code" arrangement. Only for the 8 ft couplers. The other couplers 4 ft, 16 ft,etc have white LEDs.
The next addition will be a crescendo position indicator using a 20 segment tri-color LED bargraph such as
