[PD] Pd-X update confusion

Your best bet is to use the default preferences, i.e. remove  
~/.pdextended.  For example, you need to first load the 'libdir'  
library in order to load the rest.  If you want to maintain a custom  
~/.pdextended, then use the included preferences in /usr/lib/pd- 

I think the best way to manage preferences is to embed them into the  
patch itself, i.e. using [import], [declare].  For audio and midi  
settings see these help patches in the Help Browser:

hcs -> get-audio-dialog-help.pd
hcs -> get-midi-dialog-help.pd

But I must confess, I almost always use the built-in audio on my  
laptop, so my setup is quite simple.

glad of an opportunity to serve others by any invention of ours; and  
this we should do freely and generously.         - Benjamin Franklin
