I'm sorry but how would I go about getting a midi input into a PD patch and outputting it onto a workstation like logic? thank you

Midi notes or control changes?

For the latter use [notein] and [noteout]

For the former use [ctlin] and [ctlout]

Then use a midi loopback system like maple midi

or if you are on a mac the IAC bus usually works fine for me but sometimes i have to use midi pipe
what kind of things are you going to try and do with this midinformation
my experience has always been when you take a note and do some fun number mangling you will have to restructure it as a proper midi note (note,vel,channel)

like how would i go about using http://puredata.hurleur.com/sujet-2102-know-know-stutter-patch this patch, using a midi controller and feeding it to logic pro? and yes i'm on a mac and using the IAC bus
