ALTERABLE ORGAN STOPS MAY BE COMBINED FOR UP TO 21 SIMULTANEOUS ORGANS SOLO STOPS ARE TAB TYPE IN CENTER SECTION.
Each organ selector drawknob enables an overlay rank to each of the listed stops.
For example the organ selector stop #1 for the Pedal/ Solo/Swell divisions is the original Allen 1800 ranks engraved on each drawknob. If you pull the Alterable organ #2 stop drawknob it will add midi enabled ranks to the same stops with the voicing determined by the stop program. A flute 8' stop should have midi 8' Flute(s) midi program for that stop. Any number of flutes can be assigned to that same stop. With this unique configuration, any number of combinations are possible yet keeping the number of stops reasonable. Literally thousands of ranks and millions of combinations are possible.
