I see.  I was thinking not of using '*' as a duration, but of omitting the 
duration part of r4*1.

  r4       quarter rest
  r        rest of default duration
  r4*2/3   quarter rest compressed to 2/3 of its duration
  r*2/3    rest of the default duration, compressed to 2/3 of it

So r*1 would use the unscaled default duration.
