[PD] Using dual processor to manage 2 Pd at the same time

You can achieve that by starting one instance of pd in the usual way (for
audio process by example) and the other one using the terminal app , writing
there the adress to the app and starting it with the ./Pd-extended command
by example....it is recommended that you start the pd instace for video
(gem) with -noaudio flag or, alternatively desctivating the audio in the
menu of the app.
I have used that approach with success for audio and video processing in
real-time like this:
hope it helps
