Re: increasing min. distance between staves in a PianoStaff

Hi Tao,

Sorry… rereading your post, I see that your question was pretty clear  
(and I am, apparently, pretty dense this morning).
The following should give you a hint on how to keep a minimum  
distance in a PianoStaff — I don't think there's a "simpler" method  
(this one's pretty easy, IMO).

HTH!
