[PD] midifile

[oliver]

hi, martin

on Pd version 0.38.3 (XP) i can't load your compiled "midifile.dll" although it's in the 
search path.

i downloaded it from here:

http://puredata.info/Members/martinrp

and the .dll version seems to be the latest.


am i missing something. do i need another version of PD for this to work under XP ?

any help appreciated

ciao

oliver
