You can reduce the volume of the default piano in the same way, by setting 
midiMinimumVolume and midiMaximumVolume in the piano staff.  Note, though, 
that these controls only take effect on encountering a dynamic mark, so be 
sure you have a mark at the beginning of the piano notes.

BTW, an easier way may be to simply use quieter dynamic marks on the music 
of the instruments you want to reduce - these also affect the MIDI volume.

Sorry, apart from using separate versions I don't know how to do this other 
than by writing a Scheme procedure to add the staccato marks in the midi 
\score block.
