while this will work with Pd>=0.54, i would advice everybody to use the 
old-style extensions for the Pd32 externals:

old-style extensions will not be used by Pd64 (so there's no danger in 
accidentally loading the wrong binary), but they *can* be loaded by 
older versions of Pd (which are Pd32 only).

of course, if you are using newer features that require Pd>=0.54 anyhow 
(e.g. multichannel), then by all means use the new-style extensions for 
Pd32 as well.
