Hi Mike,

I'm getting an error with this on my machine with this. 'Csound tidy
up: Illegal instruction'.
Reading here, I think it must be built to support some operations my
cpu can't use:
http://csound.1045644.n5.nabble.com/Csound-tidy-up-Illegal-instruction-td1101110.html
I've a pentium 4 so its old, but not ancient. Does that sound like it
might be whats causing the problem?
I'm really looking forward to exploring cs6. Its certainly an exciting
time for csound!

Thanks,
 Joel

This is a Pentium 4 'Northwood' which supports only MMX and SSE1/2.
Csound crashes before doing anything, one line after loading rtmidi.
I've since found an AMD machine which runs cs6 fine but I'm probably
not the only person with such an old machine.

Regards,
 Joel

It appears that that facility only appears in Vista and later. I do not 
have it in XP, it simply shows "Pentium 4". I suspect however mine is 
probably an early model, just supporting up to SSE2, which suggests it 
will not run Csound6. An end of an era!
