Ciao fioj, I have 3 patches. I need to use the first... then close it; to use the second... then close it; and finally to use the third! BUT every patch has its own MIDI-setting. So I need manually to change the MIDI preferences every time! Is there the possibility to save the MIDI-setting of a patch in the patch it-self?

Pd-extended comes with an abstraction called [get-midi-dialog] that's used for this. It's in the hcs library.

WOW! Excellent!
