Hi Robin,
     Thanks for the reply.  That clears up some things, but I'm still a little 
confused: let's say I open up the IR, start in the Voice context, 
and click the layout object TieColumn.  Now at the bottom of the TieColumn 
page, it says, "This object supports the following interface(s)..." and 
there's the grob-interface.

I previously thought that everything listed under the grob-interface 
would be common to all grobs, so that if you know something is a grob, you 
also know definitively that you can make it invisible with 'transparent, 
for example.

But since that's not the case, why does it say "This object supports..." 
at the bottom of the page for the object?  Does that mean they are 
available but not necessarily implemented?

Ah, I'll keep this file in mind for future problems.

Thanks.  I finally found a solution by just using a sextuplet in the 
right hand as well, and hiding the notes but leaving the ties. 
tieWaitForNote is very handy.
