Hi Uncle Dave,
Another approach to long sustain (or hold) is to use the Sostenuto setting on the foot switch pedal. Unfortunately this appears to work on only one of the right hand parts at a time so if you wish to hold piano and strings you have to use one of the combination voices or edit your own.
Cheers
Len C.
