[PD] midi pd and logic

[Julian Peterson]

I have had much luck with this.  There are a couple of things you  
will need:

The first is jack, which is an audio server that can be used to route  
audio data between applications.  It can be found here:
www.jackosx.com

Secondly, you need a version of PD that is compiled with Jack  
support.  Miller's official version does not include jack support for  
the Mac (at least, I don't believe it does), so I use the HCS  
version, which can be found here:

OSX has a built in midi routing bus called the IAC bus (inter- 
application connect) that can be used to send midi between Logic and  
PD.  You'll need to be careful when using this with Logic because you  
can easily cause MIDI loops that will lock up your computer.  I got  
it working by using the channel splitter in Logic's environment setup  
to allow logic to only receive midi on a few specific channels and  
then not using those channels with the IAC bus.  Setting up the logic  
environment is the most difficult part of this whole operation  
(beyond learning how to use PD, of course).  If you need help with  
setting up Logic, email me off list and I can be more specific.

Once I got everything setup properly, it was easy to integrate the  
two.  My studio these days is Logic, Pure Data, and Csound (with the  
blessed csoundapi~ object).

Hope that helps.
