OK, probably a good reason to use doubles for internal math

Stuff to read, thanks!

Agreed.

Hm. Yes. it depends on the type of operations done, and there are (many)
cases where fixed point math actually is inferior.
I mainly assumed the PT guys do all this "faffing about" to make sure
those shortcomings don't degrade audio quality, but maybe they cannot
guarantee this for any plugin.
Wha'ever. I'm not into PT and this will most likely never change.

Thanks Erik,
