Hi!!
I m wishing to start to approach raspberry pi, with Purr Data.
Do you know if there is any difference with the normal PD??

@gidigi The simplest way of getting started on the rpi / pd is to use this product: https://blokas.io/ (pisound). You will be able to make music very quickly.

But to answer your question, there's no difference between pd on rpi or pd on win, mac, linux. The only difference is the hardware / software architecture (and processing power).

Cheers~
