Nope, I increased the RAM on perf.ppc and it still choked on the 25  
MB score file.

You may or will get a similar looking memory error if the density of
events (number of instruments allocated) is too high.  This sometimes
happens with matt's score generator, e.g.  I think the only way to
adjust for this is for the programmer to make a fixed pool larger. If
you make the instruments smaller and the program behaves differently,
that may be the case.  The memory allocation scheme for instantiations
of instruments, if I remember right, is not quite so forgiving or smart
as that for score files.  Something to put on the list, I guess.

as i recall, you are not getting a "memory allocation error" message, is
that correct?  it sorts the score fine, then starts cruching along, then
just stops the generation at some point?
