NP, thanks :)

Yes...  The problem here is that they've implemented a interpolation
resampling algorithm in MMX without a "pure code" equivalent. 
So, when I turn off MMX, I lose the interpolation.

The SID is so "gritty" anyway that it hardly makes any difference
but it is a shame.

Oh and yes, there is no difference for the MIDI output.  Its just the WAV
output and play-back that's affected.  The MMX code is in the ReSID
library, not in the applications.

BTW, I'm in the process of a code clean-up.  Ian didn't get back to me
"today" so no further progress on the MacOS port.  Hopefully
he'll be able to work on it "tomorrow" (we're in different time
zones).
