In the 100126 MMD Larry Schuette asks about what the pallets on the
Duo-Art soft pedal are connected to.  In some Duo-Arts there is only
one pallet.  If so, it usually goes to A-2, but sometimes to A-1.  If
there are two pallets, sometimes one goes to A-1 and T-2, sometimes to
A-2 and T-2, depending on the piano and its needs and its environment.
Many were not hooked up at all.
